Miscellaneous Chisel IP

Some very basic IP for everyday use, written in Chisel 3.0. Currently contains:

• DataWidthConverter
  Converts UInt of arbitrary bit width to UInt of different bit width. Zero delay, handshaked channels using Chisels Decoupled interface.

• DecoupledDataSource
  Generic data provider with fixed (compile-time) data; uses handshakes via Chisels Decoupled interface.

• SignalGenerator
  Primitive 1-bit signal generator: Specify via change list, can cycle.

These were basically warm-up exercises with Chisel, but can be useful now and then. For usage examples see the unit test suites.
