+     otherwise restricted by copyright and certain other rights. Our licenses are
+     irrevocable. Licensors should read and understand the terms and conditions

+:xlarge:`Creative Commons Attribution 4.0 International Public License`
+
+By exercising the Licensed Rights (defined below), You accept and agree to be
+bound by the terms and conditions of this Creative Commons Attribution 4.0
+International Public License ("Public License"). To the extent this Public
+License may be interpreted as a contract, You are granted the Licensed Rights
+in consideration of Your acceptance of these terms and conditions, and the
+Licensor grants You such rights in consideration of benefits the Licensor
+receives from making the Licensed Material available under these terms and
+conditions.
+
+Section 1 – Definitions.
+========================
+
+a. **Adapted Material** means material subject to Copyright and Similar
+   Rights that is derived from or based upon the Licensed Material and in
+   which the Licensed Material is translated, altered, arranged, transformed, or
+   otherwise modified in a manner requiring permission under the Copyright and
+   Similar Rights held by the Licensor. For purposes of this Public License,
+   where the Licensed Material is a musical work, performance, or sound
+   recording, Adapted Material is always produced where the Licensed Material
+   is synched in timed relation with a moving image.
+
+b. **Adapter's License** means the license You apply to Your Copyright and
+   Similar Rights in Your contributions to Adapted Material in accordance with
+   the terms and conditions of this Public License.
+
+c. **Copyright and Similar Rights** means copyright and/or similar rights
+   closely related to copyright including, without limitation, performance,
+   broadcast, sound recording, and Sui Generis Database Rights, without regard
+   to how the rights are labeled or categorized. For purposes of this Public
+   License, the rights specified in Section 2(b)(1)-(2) are not Copyright and
+   Similar Rights.
+
+d. **Effective Technological Measures** means those measures that, in the
+   absence of proper authority, may not be circumvented under laws fulfilling
+   obligations under Article 11 of the WIPO Copyright Treaty adopted on
+   December 20, 1996, and/or similar international agreements.
+
+e. **Exceptions and Limitations** means fair use, fair dealing, and/or any
+   other exception or limitation to Copyright and Similar Rights that applies to
+   Your use of the Licensed Material.
+
+f. **Licensed Material** means the artistic or literary work, database, or
+   other material to which the Licensor applied this Public License.
+
+g. **Licensed Rights** means the rights granted to You subject to the terms
+   and conditions of this Public License, which are limited to all Copyright and
+   Similar Rights that apply to Your use of the Licensed Material and that the
+   Licensor has authority to license.
+
+h. **Licensor** means the individual(s) or entity(ies) granting rights under
+   this Public License.
+
+i. **Share** means to provide material to the public by any means or process
+   that requires permission under the Licensed Rights, such as reproduction,
+   public display, public performance, distribution, dissemination,
+   communication, or importation, and to make material available to the public
+   including in ways that members of the public may access the material from a
+   place and at a time individually chosen by them.
+
+j. **Sui Generis Database Rights** means rights other than copyright
+   resulting from Directive 96/9/EC of the European Parliament and of the
+   Council of 11 March 1996 on the legal protection of databases, as amended
+   and/or succeeded, as well as other essentially equivalent rights anywhere
+   in the world.
+
+k. **You** means the individual or entity exercising the Licensed Rights
+   under this Public License. **Your** has a corresponding meaning.
+
+Section 2 – Scope.
+==================
+
+a. **License grant.**
+
+   1. Subject to the terms and conditions of this Public License, the Licensor
+      hereby grants You a worldwide, royalty-free, non-sublicensable,
+      non-exclusive, irrevocable license to exercise the Licensed Rights in the
+      Licensed Material to:
+
+       A. reproduce and Share the Licensed Material, in whole or in part; and
+
+       B. produce, reproduce, and Share Adapted Material.
+
+   2. :underline:`Exceptions and Limitations.` For the avoidance of doubt, where
+      Exceptions and Limitations apply to Your use, this Public License does not
+      apply, and You do not need to comply with its terms and conditions.
+
+   3. :underline:`Term.` The term of this Public License is specified in Section 6(a).
+
+   4. :underline:`Media and formats`; :underline:`technical modifications allowed.` The Licensor
+      authorizes You to exercise the Licensed Rights in all media and formats
+      whether now known or hereafter created, and to make technical
+      modifications necessary to do so. The Licensor waives and/or agrees not to
+      assert any right or authority to forbid You from making technical
+      modifications necessary to exercise the Licensed Rights, including
+      technical modifications necessary to circumvent Effective Technological
+      Measures. For purposes of this Public License, simply making modifications
+      authorized by this Section 2(a)(4) never produces Adapted Material.
+
+   5. :underline:`Downstream recipients.`
+
+       A. :underline:`Offer from the Licensor – Licensed Material.` Every recipient of
+          the Licensed Material automatically receives an offer from the
+          Licensor to exercise the Licensed Rights under the terms and
+          conditions of this Public License.
+
+       B. :underline:`No downstream restrictions.` You may not offer or impose any
+          additional or different terms or conditions on, or apply any Effective
+          Technological Measures to, the Licensed Material if doing so restricts
+          exercise of the Licensed Rights by any recipient of the Licensed
+          Material.
+
+   6. :underline:`No endorsement.` Nothing in this Public License constitutes or may
+      be construed as permission to assert or imply that You are, or that Your
+      use of the Licensed Material is, connected with, or sponsored, endorsed,
+      or granted official status by, the Licensor or others designated to
+      receive attribution as provided in Section 3(a)(1)(A)(i).
+
+b. **Other rights.**
+
+   1. Moral rights, such as the right of integrity, are not licensed under this
+      Public License, nor are publicity, privacy, and/or other similar
+      personality rights; however, to the extent possible, the Licensor waives
+      and/or agrees not to assert any such rights held by the Licensor to the
+      limited extent necessary to allow You to exercise the Licensed Rights, but
+      not otherwise.
+
+   2. Patent and trademark rights are not licensed under this Public License.
+
+   3. To the extent possible, the Licensor waives any right to collect royalties
+      from You for the exercise of the Licensed Rights, whether directly or
+      through a collecting society under any voluntary or waivable statutory or
+      compulsory licensing scheme. In all other cases the Licensor expressly
+      reserves any right to collect such royalties.
+
+Section 3 – License Conditions.
+===============================
+
+Your exercise of the Licensed Rights is expressly made subject to the following conditions.
+
+a. **Attribution.**
+
+   1. If You Share the Licensed Material (including in modified form), You must:
+
+       A. retain the following if it is supplied by the Licensor with the
+          Licensed Material:
+
+         i. identification of the creator(s) of the Licensed Material and any
+            others designated to receive attribution, in any reasonable manner
+            requested by the Licensor (including by pseudonym if designated);
+
+         ii. a copyright notice;
+
+         iii. a notice that refers to this Public License;
+
+         iv. a notice that refers to the disclaimer of warranties;
+
+         v. a URI or hyperlink to the Licensed Material to the extent reasonably
+            practicable;
+
+       B. indicate if You modified the Licensed Material and retain an
+          indication of any previous modifications; and
+
+       C. indicate the Licensed Material is licensed under this Public License,
+          and include the text of, or the URI or hyperlink to, this Public
+          License.
+
+   2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner
+      based on the medium, means, and context in which You Share the Licensed
+      Material. For example, it may be reasonable to satisfy the conditions by
+      providing a URI or hyperlink to a resource that includes the required
+      information.
+
+   3. If requested by the Licensor, You must remove any of the information
+      required by Section 3(a)(1)(A) to the extent reasonably practicable.
+
+   4. If You Share Adapted Material You produce, the Adapter's License You apply
+      must not prevent recipients of the Adapted Material from complying with
+      this Public License.
+
+Section 4 – Sui Generis Database Rights.
+========================================
+
+Where the Licensed Rights include Sui Generis Database Rights that apply to Your
+use of the Licensed Material:
+
+a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract,
+   reuse, reproduce, and Share all or a substantial portion of the contents of
+   the database;
+
+b. if You include all or a substantial portion of the database contents in a
+   database in which You have Sui Generis Database Rights, then the database
+   in which You have Sui Generis Database Rights (but not its individual
+   contents) is Adapted Material; and
+
+c. You must comply with the conditions in Section 3(a) if You Share all or a
+   substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not replace
+Your obligations under this Public License where the Licensed Rights include
+other Copyright and Similar Rights.
+
+Section 5 – Disclaimer of Warranties and Limitation of Liability.
+=================================================================
+
+a. **Unless otherwise separately undertaken by the Licensor, to the extent
+   possible, the Licensor offers the Licensed Material as-is and as-available,
+   and makes no representations or warranties of any kind concerning the
+   Licensed Material, whether express, implied, statutory, or other. This
+   includes, without limitation, warranties of title, merchantability,
+   fitness for a particular purpose, non-infringement, absence of latent or
+   other defects, accuracy, or the presence or absence of errors, whether or
+   not known or discoverable. Where disclaimers of warranties are not allowed
+   in full or in part, this disclaimer may not apply to You.**
+
+b. **To the extent possible, in no event will the Licensor be liable to You
+   on any legal theory (including, without limitation, negligence) or
+   otherwise for any direct, special, indirect, incidental, consequential,
+   punitive, exemplary, or other losses, costs, expenses, or damages arising
+   out of this Public License or use of the Licensed Material, even if the
+   Licensor has been advised of the possibility of such losses, costs, expenses,
+   or damages. Where a limitation of liability is not allowed in full or in
+   part, this limitation may not apply to You.**
+
+c. The disclaimer of warranties and limitation of liability provided above
+   shall be interpreted in a manner that, to the extent possible, most
+   closely approximates an absolute disclaimer and waiver of all liability.
+
+Section 6 – Term and Termination.
+=================================
+
+a. This Public License applies for the term of the Copyright and Similar Rights
+   licensed here. However, if You fail to comply with this Public License, then
+   Your rights under this Public License terminate automatically.
+
+b. Where Your right to use the Licensed Material has terminated under
+   Section 6(a), it reinstates:
+
+   1. automatically as of the date the violation is cured, provided it is cured
+      within 30 days of Your discovery of the violation; or
+
+   2. upon express reinstatement by the Licensor.
+
+   For the avoidance of doubt, this Section 6(b) does not affect any right the
+   Licensor may have to seek remedies for Your violations of this Public License.
+
+c. For the avoidance of doubt, the Licensor may also offer the Licensed Material
+   under separate terms or conditions or stop distributing the Licensed Material
+   at any time; however, doing so will not terminate this Public License.
+
+d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.
+
+Section 7 – Other Terms and Conditions.
+=======================================
+
+a. The Licensor shall not be bound by any additional or different terms or
+   conditions communicated by You unless expressly agreed.
+
+b. Any arrangements, understandings, or agreements regarding the Licensed
+   Material not stated herein are separate from and independent of the terms
+   and conditions of this Public License.
+
+Section 8 – Interpretation.
+===========================
+
+a. For the avoidance of doubt, this Public License does not, and shall not be
+   interpreted to, reduce, limit, restrict, or impose conditions on any use of
+   the Licensed Material that could lawfully be made without permission under
+   this Public License.
+
+b. To the extent possible, if any provision of this Public License is deemed
+   unenforceable, it shall be automatically reformed to the minimum extent
+   necessary to make it enforceable. If the provision cannot be reformed, it
+   shall be severed from this Public License without affecting the
+   enforceability of the remaining terms and conditions.
+
+c. No term or condition of this Public License will be waived and no failure to
+   comply consented to unless expressly agreed to by the Licensor.
+
+d. Nothing in this Public License constitutes or may be interpreted as a
+   limitation upon, or waiver of, any privileges and immunities that apply to
+   the Licensor or You, including from the legal processes of any jurisdiction
+   or authority.

+Register Map
+************
+
+All registers are read-only. Version Register should always start with offset ``0x80000000`` (First PL Address).
+
+.. tip::
+
+   The version register should be the first address in the address space (e.g., ``0x8000_0000``), thus a software can
+   check what PL firmware is active and if this firmware is compatible to the currently running software version.

+
+The :comp:`axi4lite_Register` is a generic implementation of :term:`memory-mapped-registers (MMR) <MMR>` providing an
+:term:`AXI4-Lite` communication interface. The register layout is describe by a generic constant called
+:ref:`IP/axi4lite_Register/gen/CONFIG`. This constant is :ref:`constructed <IP/axi4lite_Register/configuration>` by
+various helper functions as described in the following sections.
+
+
+.. _IP/axi4lite_Register/goals:
+
+.. topic:: Design Goals
+
+   * The register is described completely within VHDL.
+
+     * Pure VHDL code offers the single-source of truth.
+     * VHDL language constructs (function, loop, if-then-else, ...) can be utilized to describe register layouts.
+     * A register description in YAML format is exported at :term:`elaboration time` (synthesis or simulation).
+
+   * The register supports 32/64-bit AXI4-Lite buses.
+   * Support optimized registers within the same register structure:
+
+     * Support constant read-only registers for fixed values like generic parameters.
+     * Support fall-through registers to provide access e.g. to transmit and receive :term:`FIFOs <FIFO>`.
+
+   * The register can generate interrupts
+
+.. _IP/axi4lite_Register/features:
+
+.. topic:: Features
+
+   * Supports 32-bit (4-byte aligned) and 64-bit registers (8-byte aligned).
+   * Supports 32-bit and 64-bit AXI4-Lite interface.
+   * Indicate register access from AXI4-Lite as a *hit* signal.
+   * Sparse register address support (address range can have unaccessible addresses).
+   * Generate interrupt requests depending on register configurations.
+
+     * Configurable IRQ pattern: :term:`strobe` vs. :term:`flag`.
+     * Provide interrupt reason and interrupt enable registers if interrupt causing registers are configured.
+     * Configurable interrupt reason register address.
+     * Configurable interrupt enable register address.
+
+   * AXI4 error handling and response codes:
+
+     * Generate negative AXI4 response on permission errors (e.g. writing on a readonly register)
+     * Generate negative AXI4 response on addressing errors (e.g. access to non-existing address)
+     * Configurable AXI4 response code in case of access errors.
+
+   * Configurable reset behavior:
+
+     * Reload initial register values on reset.
+
+   * If in debug mode, mark important signals as ``debug`` and write register configuration and internal calculations
+     into synthesis log.

+
+Instantiation
+*************
+
+Depending on the complexity of the register (number of registers, register modes, repeated groups), various VHDL coding
+styles (also with vary complexity) can be used to configure the axi4lite_Register completely in VHDL. No external
+scripting or code generation is needed to describe and use the AXI4-Lite register.

+Simple Register
+===============
+
+.. grid:: 2
+
+   .. grid-item::
+      :columns: 5
+
+      The example code on the right side demonstrates a simple 32-bit AXI4-Lite register offering two registers at
+      addresses :vhdlcode:`0x00` and :vhdlcode:`0x04`. The first register is configured in read-write mode, the second
+      one is in read-only mode. The register description array is provided directly in the *generic map* to the
+      :ref:`IP/axi4lite_Register/gen/CONFIG` parameter within the register instantiation.
+
+      The *port map* connect the system signals :ref:`IP/axi4lite_Register/port/Clock` and
+      :ref:`IP/axi4lite_Register/port/Reset` as well as the AXI4-Lite interface consisting of
+      :ref:`IP/axi4lite_Register/port/AXI4Lite_m2s`, :ref:`IP/axi4lite_Register/port/AXI4Lite_s2m` and
+      :ref:`IP/axi4lite_Register/port/AXI4Lite_irq` to the AXI4-Lite infrastructure.
+
+      For this simple read and write use-model, only ports :ref:`IP/axi4lite_Register/port/RegisterFile_ReadPort` and
+      :ref:`IP/axi4lite_Register/port/RegisterFile_WritePort` are required.
+
+      .. hint::
+
+         The naming is chosen from **fabric view**, thus writing is from fabric to register and reading is from register
+         to fabric.
+
+      The following code accesses a single register by it's configuration index according to the configuration generic
+      (this is not the register offset).
+
+      .. code-block:: vhdl

+
+         my_Value32Bit <= ReadPort(0);      -- register 'Value'
+
+      A register value can be provided from VHDL code as follows:
+
+      .. code-block:: vhdl
+
+         signal my_Status32Bit : std_logic_vector(31 downto 0);

+Register Description from Generator Function
+============================================
+
+.. grid:: 2
+
+   .. grid-item::
+      :columns: 5
+
+      A register description is an array of type :type:`T_AXI4_Register_Vector`. Such an array can be constructed by an
+      aggregate expression (see :ref:`IP/axi4lite_Register/inst/Simple`), by calling a user-defined helper function or
+      by concatenating results from multiple user-defined helper functions.
+
+      The example code on the right side demonstrates how local signals can be sized based on a :vhdlcode:`CONFIG`
+      constant.The constant itself is computed by a user-defined function. See section
+      :ref:`IP/axi4lite_Register/configuration` for details.
+
+      When a register is access from AXI4-Lite side, a hit event (:term:`strobe`) is generated. In case an AXI4-Lite
+      read operation was executed and a matching register offset was decoded, a corresponding bit is active for one
+      clock cycle in :ref:`IP/axi4lite_Register/port/RegisterFile_WritePort_hit`. Similarly, in case an AXI4-Lite write
+      operation was executed and a matching register offset was decoded, a corresponding bit within
+      :ref:`IP/axi4lite_Register/port/RegisterFile_ReadPort_hit` is asserted for one clock cycle.
+
+      .. admonition:: Advantages of a generator function
+
+         Employing a user-defined helper function offer multiple advantages:
+
+         * Encapsulate register description generation in a local or global VHDL function.
+         * Use VHDL language constructs like concatenation, loops, if-then-else or other subprogram to construct a
+           description.
+         * Automate register names and register offset incrementation.
+         * Generate registers based on function parameters (e.g. from generics).
+         * Store the register description in a constant.
+         * Lookup register indices by name.

+The IP core offers a system interface (clock, reset), the AXI4-Lite interface and access to the internal registers from
+fabric.

+
+   The naming of fabric ports is from fabric point-of-view. However, the naming of register modes like ``ReadOnly`` is

+-----------------
+
+:Name:          :generic:`CONFIG`
+:Type:          :type:`AXI4Lite:T_AXI4_Register_Vector`
+:Default Value: — — — —
+:Description:   Register description as an array of :type:`AXI4Lite:T_AXI4_Register` values. Usually, these array
+                elements are constructed by the helper function :subprog:`to_AXI4_Register`.
+
+                See :ref:`IP/axi4lite_Register/configuration`
+
+
+.. _IP/axi4lite_Register/gen/INTERRUPT_IS_STROBE:
+
+:generic:`INTERRUPT_IS_STROBE`
+------------------------------
+
+:Name:          :generic:`INTERRUPT_IS_STROBE`
+:Type:          :type:`boolean`
+:Default Value: ``true``
+:Description:   Define the behavior of the interrupt request port :ref:`IP/axi4lite_Register/port/AXI4Lite_irq`.
+
+                If this generic is ``true``, a :term:`edge (strobe) <strobe>` interrupt is generated, otherwise a
+                :term:`level (flag) <flag>` interrupt.
+
+                .. todo::
+
+                   With this generic, it can be selected if the Interrupt-pin should through an interrupt as ``Strobe``
+                   or ``Value``. By selecting ``Strobe``, the module will block a new interrupt until the
+                   ``INTERRUPT_MATCH_REGISTER`` is read out.
+
+
+.. _IP/axi4lite_Register/gen/INTERRUPT_ENABLE_REGISTER_ADDRESS:
+

+--------------------------------------------
+
+:Name:          :generic:`INTERRUPT_ENABLE_REGISTER_ADDRESS`
+:Type:          :type:`unsigned`
+:Default Value: ``x"00"``
+:Description:   If Interrupts are used, this generic selects the address of the internal ``INTERRUPT_ENABLE_REGISTER``.
+
+
+.. _IP/axi4lite_Register/gen/INTERRUPT_MATCH_REGISTER_ADDRESS:
+
+:generic:`INTERRUPT_MATCH_REGISTER_ADDRESS`
+-------------------------------------------
+
+:Name:          :generic:`INTERRUPT_MATCH_REGISTER_ADDRESS`
+:Type:          :type:`unsigned`
+:Default Value: ``x"04"``
+:Description:   If Interrupts are used, this generic selects the address of the internal ``INTERRUPT_MATCH_REGISTER``.
+
+
+.. _IP/axi4lite_Register/gen/INIT_ON_RESET:
+
+:generic:`INIT_ON_RESET`
+------------------------
+
+:Name:          :generic:`INIT_ON_RESET`
+:Type:          :type:`boolean`
+:Default Value: ``true``
+:Description:   The Init-value of the registers, that is set by the ``Config``, is set by default with the Reset. This
+                can be disabled here. This helps with reducing control-sets and therefore helps by CLB utilization.
+
+
+.. _IP/axi4lite_Register/gen/IGNORE_HIGH_ADDRESS:
+
+:generic:`IGNORE_HIGH_ADDRESS`
+------------------------------
+
+:Name:          :generic:`IGNORE_HIGH_ADDRESS`
+:Type:          :type:`boolean`
+:Default Value: ``true``
+:Description:   The module will calculate based on the configuration how many bits are needed to address every specified
+                register. If this generic is set, it will ignore every bit which is coming after the needed address-bits.
+                These bits are considered as base address. By setting this value, you can pass the full 40/32bit from
+                Zynq, and it will filter out the base address for it.
+
+
+.. _IP/axi4lite_Register/gen/RESPONSE_ON_ERROR:

+----------------------------
+
+:Name:          :generic:`RESPONSE_ON_ERROR`

+:Default Value: ``C_AXI4_RESPONSE_DECODE_ERROR``
+:Possible Values: ``C_AXI4_RESPONSE_OKAY``, ``C_AXI4_RESPONSE_EX_OKAY``, ``C_AXI4_RESPONSE_SLAVE_ERROR`` or ``C_AXI4_RESPONSE_DECODE_ERROR``
+:Description:   With this generic can be selected which response code should be sent out if an address is accessed that
+                is not handled by ``Config``.
+
+
+.. _IP/axi4lite_Register/gen/DISABLE_ADDRESS_CHECK:
+
+:generic:`DISABLE_ADDRESS_CHECK`
+--------------------------------
+
+:Name:          :generic:`DISABLE_ADDRESS_CHECK`
+:Type:          :type:`boolean`

+.. _IP/axi4lite_Register/config/Registers:
+
+Register Description
+====================
+
+The configuration can be created in many different ways. If the register is small, it can be done like above by directly
+setting the register in the generic. This approach has the disadvantage that the index of the read and write port is
+changing if an register is added later. This can easily create errors inside the design, if not each and every index is
+checked and updated if needed. This is why this approach **is not commanded**.
+
+The next step is to save the Config inside a constant. If done like this, the register can also use the `Name`-field.
+If all register are named, the index of the register can be calculated by helper-functions with its specific name (See
+next section `Helper Functions`). This helps to prevent from errors and allows easily to extend the register because the
+index is calculated new and updated appropriate. This approach is only suitable for mid-complex registers.
+
+
+.. code-block:: vhdl
+
+   function genConfig return T_AXI4_Register_Vector is
+     variable temp : T_AXI4_Register_Vector(0 to 511);
+     variable addr : natural := 0;
+     variable pos  : natural := 0;
+   begin
+     temp(pos) := to_AXI4_Register(Name => "System.Version", Address => to_unsigned(addr, 32), Init_Value => std_logic_vector(to_unsigned(3, 32)), rw_config => constant_fromInit);
+     addr := addr +4; pos  := pos +1;
+     temp(pos) := to_AXI4_Register(Name => "System.Status",Address => to_unsigned(addr, 32), rw_config => readable);
+     addr := addr +4; pos  := pos +1;
+
+     addr := 256;
+     temp(pos) := to_AXI4_Register(Name => "System.Command",Address => to_unsigned(addr, 32), rw_config => readWriteable, Auto_Clear_Mask => x"FFFFFFFF");
+     addr := addr +4; pos  := pos +1;
+
+     return temp(0 to pos -1);
+   end function;
+
+   constant CONFIG : T_AXI4_Register_Vector := gen_config;
+
+
+This example configuration creates a total of three registers. After one register is created the index/position is
+incremented by one and the address by 4. The addresses are adapting automatically. As can be seen, the third register is
+shifted to address 0x100 by overwriting the addr variable. This creates an empty space between 0x4 and 0x100, which is
+creating a ``RESPONSE_ON_ERROR`` code while read or write access.
+
+In this function registers can be created also as a loop:
+
+.. code-block:: vhdl
+
+   for i in 0 to Num_RTT -1 loop
+     temp(pos) := to_AXI4_Register(Name => "Data_Value(" & integer'image(i) & ")", Address => to_unsigned(addr, 32), rw_config => readable);
+	  pos := pos +1; addr := addr +4;
+	end loop;
+
+By giving each loop-register a different name dependent on the constant `i`, it can be referenced separately.
+
+

+.. _IP/axi4lite_Register/config/Modes:
+
+Register Modes
+==============
+
+For each register, a mode can be selected with the field `rw_config`. This mode depends on the functionality that should
+be achieved. Possible modes are:
+
+
+:value:`ConstantValue`
+----------------------
+
+:Mode:        :value:`ConstantValue`
+:Behavior:    constant value
+:Description: This Mode connects the ``Init_Value`` directly to the read-mux. No Flip-Flop is created and the Read and
+              Write Port is unconnected.
+
+
+:value:`ReadOnly`
+-----------------
+
+:Mode:        :value:`ReadOnly`
+:Description: This Mode is used to provide a Status register.
+
+
+:value:`ReadOnly_NotRegistered`
+-------------------------------
+
+:Mode:        :value:`ReadOnly_NotRegistered`
+:Description: As ``readable`` but does not create flip-flops internally. The WritePort is directly connected to the
+              read-mux. Can be used if data is already driven by registers or if path is not time-critical.
+
+
+:value:`ReadWrite`
+------------------
+
+:Mode:        :value:`ReadWrite`
+:Description: This Mode can be used to configure or control the PL form SW. Software can write into this register, and
+              it will be visible through `RegisterFile_ReadPort`. The PL can also overwrite the Value by setting the
+              corresponding bit in port `RegisterFile_WritePort_strobe`. In this mode, the field ``Auto_Clear_Mask`` is
+              active. It can be used to control FSM's with a command, that is set only for one CC.
+
+
+:value:`ReadWrite_NotRegistered`
+--------------------------------
+
+:Mode:        :value:`ReadWrite_NotRegistered`
+:Description: This mode is used only for special use-cases. It provides the internal read- and write-mux connections
+              directly to the ports, so any external functionality can be implemented. **Data on the
+              ``RegisterFile_ReadPort`` is only valid if ``RegisterFile_WritePort_strobe`` is set!** See also chapter
+              `Special Functionality`.
+
+
+:value:`LatchValue_ClearOnRead`
+-------------------------------
+
+:Mode:        :value:`LatchValue_ClearOnRead`
+:Description: ``Interrupt Capable`` After Reset or boot-up, this latch is cleared and can accept new data. If Stobe is
+              then set, the data from ``RegisterFile_WritePort`` is saved. If this value is unequal to `Init_Value`, the
+              value can not be overwritten until the SW reads it out. If latching condition is met and register is set
+              as `Is_Interrupt_Register`, and interrupt is thrown.
+
+
+:value:`LatchValue_ClearOnWrite`
+--------------------------------
+
+:Mode:        :value:`LatchValue_ClearOnWrite`
+:Description: ``Interrupt Capable`` Same as `latchValue_clearOnRead`, but it is only cleared by actively writing into
+              this register. The written value is ignored.
+
+
+:value:`LatchHighBit_ClearOnRead`
+---------------------------------
+
+:Mode:        :value:`LatchHighBit_ClearOnRead`
+:Description: ``Interrupt Capable`` By setting `Strobe`, the value of ``RegisterFile_WritePort`` is logically or-red
+              together with the current register content. So a one-bit is always added to the value. By reading this
+              register out, the software gets the value and clears it as well.
+
+
+:value:`LatchHighBit_ClearOnWrite`
+----------------------------------
+
+:Mode:        :value:`LatchHighBit_ClearOnWrite`
+:Description: ``Interrupt Capable`` Same as `latchHighBit_clearOnRead `, but it is only cleared  by actively writing
+              into this register. The written value is ignored.
+
+
+:value:`LatchLowBit_ClearOnRead`
+--------------------------------
+
+:Mode:        :value:`LatchLowBit_ClearOnRead`
+:Description: ``Interrupt Capable`` For low-active signals. By setting `Strobe`, the value of ``RegisterFile_WritePort``
+              is logically and-ed together with the current register content. So a zero-bit is always added to the
+              value. By reading this register out, the software gets the value and sets all bits as well.
+
+
+:value:`LatchLowBit_ClearOnWrite`
+---------------------------------
+
+:Mode:        :value:`LatchLowBit_ClearOnWrite`
+:Description: ``Interrupt Capable`` Same as `latchLowBit_clearOnRead `, but it is only cleared  by actively writing into
+              this register. The written value is ignored.
+
+
+:value:`Reserved`

+Helper Functions
+================
+
+For ease of use, functions are created to help for basic modifications of the configuration.
+
+filter_Register_Vector
+----------------------
+
+.. code-block:: vhdl
+
+   function filter_Register_Vector(str : string; description_vector : T_AXI4_Register_Vector) return T_AXI4_Register_Vector;
+
+Removes all elements of ``description_vector`` where `description_vector(i).name(str'range) /= str`.
+
+.. code-block:: vhdl
+
+   function filter_Register_Vector(char : character; description_vector : T_AXI4_Register_Vector) return T_AXI4_Register_Vector
+
+Removes all elements of ``description_vector`` where `description_vector(i).name(1) /= char`.
+
+add_Prefix
+----------
+
+.. code-block:: vhdl
+
+   function add_Prefix(prefix : string; Config : T_AXI4_Register_Vector; offset : unsigned(Address_Width -1 downto 0) := (others => '0')) return T_AXI4_Register_Vector;
+
+Adds the string prefix ``prefix`` to each Config(x).Name and adds the ``offset`` value to the Config(x).Address. This
+function can be used if multiple standardized (as constant) register need to be put with a prefix into the big register.
+Here is an example:
+
+.. code-block:: vhdl
+
+   constant Config_Packetizer : T_AXI4_Register_Vector := (
+     0 => to_AXI4_Register(Name => "CMD", Address => to_unsigned(0, 32), rw_config => readWriteable)
+     1 => to_AXI4_Register(Name => "CMD2", Address => to_unsigned(4, 32), rw_config => readWriteable)
+     2 => to_AXI4_Register(Name => "STATUS", Address => to_unsigned(8, 32), rw_config => readable));
+
+   function gen_config return T_AXI4_Register_Vector is
+     variable temp : T_AXI4_Register_Vector(0 to 511);
+     variable addr : natural := 0;
+     variable pos  : natural := 0;
+   begin
+     for i in 0 to 1 loop
+       temp(pos to pos + Config_Packetizer'length -1) := add_prefix("Packetizer(" & integer'image(i) & ").", Config_Packetizer, to_unsigned(addr, 32));
+       pos := pos   + Config_Packetizer'length;
+       addr := addr + Config_Packetizer'length *4;
+     end loop;
+     return temp(0 to pos -1);
+   end function;
+
+
+This will result in a config that looks like this:
+
+.. code-block:: vhdl
+
+   0 => (Name => "Packetizer(0).CMD",    Address => 32x"0",  rw_config => readWriteable),
+   1 => (Name => "Packetizer(0).CMD2",   Address => 32x"4",  rw_config => readWriteable),
+   2 => (Name => "Packetizer(0).STATUS", Address => 32x"8",  rw_config => readable),
+   3 => (Name => "Packetizer(1).CMD",    Address => 32x"C",  rw_config => readWriteable),
+   4 => (Name => "Packetizer(1).CMD2",   Address => 32x"10", rw_config => readWriteable),
+   5 => (Name => "Packetizer(1).STATUS", Address => 32x"14", rw_config => readable),

+.. _IP/axi4lite_Register/config/64BitRegister:
+
+64-bit Registers
+================
+
+The register has a 64-bit register mode. If the Data-Size of the AXI4Lite record is 64-bit wide, the AXI4Lite-Register
+will automatically put into 64-bit mode. The SW can then write 64-bit aligned into two 32-bit register at once.
+
+.. important::
+
+   The definition in the config is still done with 32-bit registers. Two 32-bit register are combined to one 64-bit
+   register. The read and write is done in the same CC and is consistent. Note that two Hits will be set for both 32-bit
+   register. If the software is making a read_32 it is not possible to know from PL which of these two registers was
+   actually read out (or written to).
+
+
+.. _IP/axi4lite_Register/config/Interrupts:
+
+Interrupts
+==========
+
+The :comp:`axi4lite_Register` is capable of creating interrupts. The ``rw_config`` needs to be a latch type to be interrupt
+capable (See section Register Mode (ReadWrite-Config)). In total, 32 registers can be set as interrupt register. This
+limitation is due to the ``interrupt match register`` width of 32 bits. If an interrupt register is latched, the
+interrupt is thrown. If the software registers an interrupt, it needs to read out the ``interrupt match register`` to
+figure out which interrupt occurred. The order of the  bits here is equal to the order of the interrupt registers in the
+config.
+
+Example:
+
+.. code-block::
+
+   Config(i) ; Name ; Address ; Init_Value ; Auto_Clear_Mask ; rw_config ; Is_Interrupt_Register
+   0 ; System.Version ; 0x00000000 ; 0x00000003 ; 0x00000000 ; constant_fromInit ; false
+   1 ; System.Test; 0x00000004 ; 0x00000000 ; 0x00000000 ; latchLowBit_clearOnRead ; true
+   2 ; System.Command ; 0x00000028 ; 0x00000000 ; 0xFFFFFFFF ; readWriteable ; false
+   3 ; System.Status ; 0x0000002C ; 0x00000000 ; 0x00000000 ; latchLowBit_clearOnRead ; true
+
+This configuration will create in total four registers of which two are interrupt registers. The
+``interrupt match register`` bit zero is mapped to `System.Test`, bit one is mapped to `System.Status`. If one of these
+bits is set, the SW needs to look into the correct address for the value. This means, if after an interrupt bit zero is
+set from in the `interrupt match register`, the SW needs to read address ``0x00000004`` afterwards to get the
+interrupt-causing-value and clear the interrupt reason.
+
+Beside the `interrupt match register`, there is also the `Interrupt enable register`. With this, you can switch on and
+off one specific register to through interrupts. The bit will still be set inside `interrupt match register`, but it
+will not create an interrupt.
+
+The addresses of both registers are set through generics. See section Interface.Generics.
+
+By using this feature, the internal configuration will add both registers in this configuration:
+
+.. code-block::
+

+Atomic Register
+===============
+
+An ``Atomic Register`` is an external wiring. This is used to avoid read-modify-write operations from software by
+introducing a `clear-bit-register`, ``set-bit-register`` and `toggle-bit-register`. A constant is prepared for this
+register inside ``AXI4Lite.pkg.vhdl`` called `Atomic_RegisterDescription_Vector`. It can be mapped/created inside of the
+``gen_config`` function like this:
+
+.. code-block:: vhdl
+
+   temp(pos to pos + Atomic_RegisterDescription_Vector'length -1) := add_prefix("My_Atomic_reg.", Atomic_RegisterDescription_Vector, to_unsigned(addr *4, 32));
+     pos := pos   + Atomic_RegisterDescription_Vector'length;
+     addr := addr + Atomic_RegisterDescription_Vector'length;
+
+.. note::
+
+   The Atomic Register should be at least 64bit aligned. If this is true, the set- and clear- mask can be written at
+   the same time.
+
+Afterwards, the wiring needs to be created in the pl like this:
+
+.. code-block:: vhdl
+
+   atomic_blk : block
+     constant low  : natural := get_index("My_Atomic_reg.ATOMIC_Value", config);
+     constant high : natural := get_index("My_Atomic_reg.ATOMIC_BitClr", config);
+
+     signal Atomic_Value     : std_logic_vector(31 downto 0) := (others => '0');
+     signal nextAtomic_Value : std_logic_vector(31 downto 0);
+   begin
+     procedure Make_AtomicRegister(
+       Reset                     => Reset,
+       RegisterFile_ReadPort     => RegisterFile_ReadPort(low to high),

+.. _IP/axi4lite_Register/Use/IO:
+
+I/O Register
+============
+
+The ``IO Register`` is used to connect a tri-state buffer directly to the register. It consists of two
+`atomic registers`. The first one for ``IO`` (Input/Output) and the second one for ``T`` (Tristate).
+
+To add it into config:
+
+.. code-block:: vhdl
+
+   temp(pos to pos + IO_RegisterDescription_Vector'length -1) := add_prefix("My_IO_reg.", IO_RegisterDescription_Vector, to_unsigned(addr *4, 32));
+     pos := pos   + IO_RegisterDescription_Vector'length;
+     addr := addr + IO_RegisterDescription_Vector'length;
+
+
+Afterwards, the wiring needs to be created in the pl like this:
+
+.. code-block:: vhdl
+
+   io_reg_blk : block
+     constant low  : natural := get_index("My_IO_reg.IO.ATOMIC_Value", config);
+     constant high : natural := get_index("My_IO_reg.T.ATOMIC_BitClr", config);
+
+     signal IO_Value     : std_logic_vector(31 downto 0) := (others => '0');
+     signal nextIO_Value : std_logic_vector(31 downto 0);
+     signal T_Value      : std_logic_vector(31 downto 0) := (others => '0');
+     signal nextT_Value  : std_logic_vector(31 downto 0);

+
+.. _IP/axi4lite_Register/Export/Naming:
+
+Naming Convention of Registers
+==============================
+
+The Name field of the configuration is limited to 64-characters. This needs to be a constant and was defined like this.
+The conversion to the C-Header file needs some properties to work. These properties are therefore defined globally.
+
+#. Each register needs to be named.
+#. Each register needs to have a unique name.
+#. The Addresses should monotonically increasing (Only for C-Header File).
+#. Multiple Registers can be grouped together with a prefix. The prefix is separated by a dot.
+#. :strike:`Multiple Prefixes can be made` :red:`This is currently not possible with the script.`
+#. A array of registers can be defined with parenthesis `(i)`. This will create and array in C-Header file.
+#. :strike:`An array can be done as well on prefixes` :red:`This is currently not possible with the script.`

+Export as YAML
+==============
+
+
+
+.. _IP/axi4lite_Register/Export/CSV:
+
+Write Register CSV File (deprecated)
+====================================
+
+A csv file can be written out of the configuration with the function `write_csv_file`. It is commanded to use it with an
+enabled ``assert`` statement or writing it into a constant. With assert, you can also see in the synthesis log if
+everything was successfully. ``PROJECT_DIR`` is a constant inside ``my_project.vhdl`` normally located at `src/PoC/`.
+
+.. code-block:: vhdl
+
+   constant success : boolean := write_csv_file(PROJECT_DIR & "gen/Sampling_Register.csv", config);
+   --or--
+   assert write_csv_file(PROJECT_DIR & "gen/Sampling_Register.csv", config) report "Error in writing csv-File!" severity warning;
+
+
+.. _IP/axi4lite_Register/Export/Convert:
+
+Create C-Header File from CSV
+=============================
+
+A big advantage of this register is the automatic register handover to the Software. This is done by converting the
+freshly generated csv file and converting it into a C-Header file. The registers specified in the config are combined
+into struct's. The final struct can than be layed over the AXI4Lite-Register Address.
+
+The conversion is done by a python-script from *************************. This python script works but has currently a
+lot of limitations.
+**It is planed to extend this script and make it accessible to the CI-Runners for automatic conversions.**
+
+
+
+
+
+
+
+
+
+
+.. #
+   AXI4Lite Register Split
+   =======================
+
+   The moduel ``axi4lite_Register_split`` is an addition to the normal register. It splits up a big register into multiple smaller ones, that can then better acheave timing. This is done by the Address-Demultiplexer `AXI4Lite_DeMux`.
+
+   This module adds the following generics:
+   | Name | Type | Default | Description |
+   |------|-------|---------|-------------|
+   | SPLIT_ON_ADDRESSBIT | natural | 0 | Split the register on this address-bit. If default (zero), it will split it up on address bit 6. This means every 0x40 will be split up. |
+   | PIPELINE_IN| natural | 0 | Adds N many pipeline-stages before the De-Mux |
+   | PIPELINE_OUT| natural | 0 | Adds N many pipeline-stages between De-Mux and all registers. |
+
+   {-Interrupts are currently not working for this module fully! It is only working if all interrupt-registers are in one sub-register and the Interrupt match and enable register addresses are located in the same sub-register.-}
+
+
+   ## AXI4Lite Register Single-Access (BRAM AXI4Lite Register)
+   {-Experimental Module-}
+   This module is a variant with singel access from PL instead parallel. With this restriction, it is possible to put the register completally into Lut-Ram or BRAM and save a lot of ressources. 1 BRAM can store in total 1k registers without timing problems.
+
+   Because it uses a dual-port-ram it has a shared access with the PL-read/write and AXI4L-read/write. To simplify the access for an potential FSM out of the PL, the access for PL is prioritized. The first port is fully reservated for the read access out of PL. The Port ``RegisterFile_ReadData`` shows always the value of address `RegisterFile_ReadAddress`. The second port is shared and has the following prioritization:
+
+   1. PL Write
+   1. AXI4L Write
+   1. AXI4L Read
+
+   Currently it is not selectable if Lut-RAM or BRAM should be used. If this is needed, ask @sunrein for this feature.

-Dependent clocks meens, that one clock must be a multiple of the other one.
-And your synthesis tool must check for setup- and hold-time violations.
-
-This implementation uses a small register-file for storing data. Your
-synthesis tool might infer memory. This memory must
-- either support asynchronous reads (as an register-file)
-- or a synchronous read with mixed-port read-during-write (write-first).
-
-First-word-fall-through (FWFT) mode is implemented, so data can be read out
-as soon as 'valid' goes high. After the data has been captured, then the
-signal 'got' must be asserted.
-
-The advantage of the register file is, that data is available at the read
-port after the rising edge of the write clock it has been written to.
-
-Because implementing register-files onto a FPGA might require a lot of LUT
-logic, use this implementation only for small FIFOs.
-
-Another disadvantage is, that the signals 'full' and
-'valid' are combinatorial and include an adress comparator in their path.
-
-The specified depth (MIN_DEPTH) is rounded up to the next suitable value.
-
-Synchronous reset is used. Both resets must overlap.

-Adapter between the :ref:`PoC.Mem <INT:PoC.Mem>`
-interface and the User Interface of the Xilinx MIG IP core for the
-Spartan-6 FPGA Memory Controller Block (MCB). The MCB can be configured to
-have multiple ports. One instance of this adapter is required for every
-port. The control signals for one port of the MIG IP core are prefixed by
-"cX_pY", meaning port Y on controller X.
-
-Simplifies the User Interface ("user") of the Xilinx MIG IP core (UG388).
-The PoC.Mem interface provides single-cycle fully pipelined read/write access
-to the memory. All accesses are word-aligned. Always all bytes of a word are
-written to the memory. More details can be found
-:ref:`here <INT:PoC.Mem>`.
-
-Generic parameters:
-
-* D_BITS: Data bus width of the PoC.Mem and MIG / MCBinterface. Also size of
-  one word in bits.
-
-* MEM_A_BITS: Address bus width of the PoC.Mem interface.
-
-* APP_A_BTIS: Address bus width of the MIG / MCB interface.
-
-Containts only combinational logic.

-Adapter between the :ref:`PoC.Mem <INT:PoC.Mem>` interface and the
-application interface ("app") of the Xilinx MIG IP core for 7-Series	FPGAs.
-
-Simplifies the application interface ("app") of the Xilinx MIG IP core.
-The PoC.Mem interface provides single-cycle fully pipelined read/write access
-to the memory. All accesses are word-aligned. Always all bytes of a word are
-written to the memory. More details can be found
-:ref:`here <INT:PoC.Mem>`.
-
-Generic parameters:
-
-* D_BITS: Data bus width of the PoC.Mem and "app" interface. Also size of one
-  word in bits.
-
-* DQ_BITS: Size of data bus between memory controller and external memory
-  (DIMM, SoDIMM).
-
-* MEM_A_BITS: Address bus width of the PoC.Mem interface.
-
-* APP_A_BTIS: Address bus width of the "app" interface.
-
-Containts only combinational logic.

-# Generated Netlists from PoC and IP Core Generators
-
-**The PoC-Library** supports the generation of netlists from pre-configured
-vendor IP cores (e.g. Xilinx Core Generator) or from bundled and pre-configured
-PoC entities. This can be done by invoking PoC's Service Tool through the wrapper
-script: `poc.[sh|ps1]`.
-
-PoC supports the following tools:
-
- -  Altera Quartus II / Quartus Prime
- -  Lattice Diamond LSE
- -  Xilinx Core Generator 14.7 (corgen)
- -  Xilinx Synthesis Tool 14.7 (xst)
-
-Planned tool support:
-
- -  Altera MegaFunction Wizard
- -  Xilinx Vivado Synth
- -  Xilinx Vivado IP Core Catalog
-
-> All Windows command line instructions are intended for **Windows PowerShell**,
-> if not marked otherwise. So executing the following instructions in Windows
-> Command Prompt (`cmd.exe`) won't function or result in errors! See the
-> [Requirements][wiki:requirements] wiki page on where to download or update
-> PowerShell.
-
-
-## 1 Common Explanations
-
-A netlist is always compiled for a specific platform. In case of an FPGA it's
-the exact device name. The name can be passed by `--device=<DEVICE>` command
-line option to the script. An alternative is the `--board=<BOARD>` option. For
-a list of well-known board names, PoC knows the soldered FPGA device.
-
-The service tool offers several common options:
-
-    Common Option           Description
-    ----------------------------------------------------------------------
-    -h   --help             Print a short help
-    -q                      Quiet-mode (print nothing)
-    -v                      Print more messages
-    -d                      Debug mode (print everything)
-    -D                      Debug wrapper script
-
-
-## 2 Compiling pre-configured Xilinx IP Cores (*.xco files) to Netlists
-
-**The PoC-Library** is shipped with some pre-configured IP cores from Xilinx.
-These IP cores are shipped as \*.xco files and need to be compiled to netlists
-(\*.ngc files) and there auxillary files (\*.ncf files; \*.vhdl files; ...). IP
-core configuration files (e.g. *.xco) are stored as regular source files in the
-`<PoCRoot>\src` directory.
-
-```PowerShell
-.\poc.ps1 [-q] [-v] [-d] coregen <PoC-Entity> [--device=<DEVICE>|--board=<BOARD>]
-```
-
-#### Use Case - Compiling all ChipScopeICON IP Cores
-
-PoC has an abstraction layer [`PoC.xil.ChipScopeICON`][xil_ChipScopeICON] to
-abstract all possible Chipscope Integrated Controller (ICON) cores
-configurations in one VHDL module. An ICON can be configured with 1 to 15
-ChipScope control ports. To use the abstraction layer it's required to
-pre-compile all 15 IP core variations.
-
-The following example compiles the first IP core with 1 port for a Kintex-7
-325T as soldered onto a KC705 board. The resulting netlist and auxillary files
-are copied to `<PoCRoot>/netlist/XC7K325T-2FFG900/xil/`. The Xilinx ISE tool
-flow requires an extension IP core search directory for *XST* and *Translate*
-(`-sd` option).
-
-```PowerShell
-cd <PoCRoot>
-.\poc.ps1 coregen PoC.xil.ChipScopeICON_1 --board=KC705
-```
-
-The compilation can be automated in a for-each loop for all IP cores:
-
-```PowerShell
-cd <PoCRoot>
-foreach ($i in 1..15)
-{	.\poc.ps1 coregen PoC.xil.ChipScopeICON_$_ --board=KC705
-}
-```
-
-
-## 3 Compiling pre-configured PoC IP Cores (bundle of VHDL files) to Netlists
-
-*Documentation is still incomplete*
-
-The IP core filelist file (*.files) and the XST option file (*.xst) are stored
-in the `<PoCRoot>\xst` directory.
-
-```PowerShell
-.\poc.ps1 [-q] [-v] [-d] xst <PoC-Entity> [--device=<DEVICE>|--board=<BOARD>]
-```
-
-#### Use Case - Compiling a Gigabit Ethernet UDP/IP Stack for a KC705 board
-
-`PoC.net.stack.UDPv4`
-
-*Documentation is still incomplete*
-
-The resulting netlist and auxillary files
-are copied to `<PoCRoot>/netlist/XC7K325T-2FFG900/net/stack`. The Xilinx ISE tool
-flow requires an extension IP core search directory for *XST* and *Translate*
-(`-sd` option).
