Integrity support ?

Dear Team,

are there any plans to support integrity signals ?

Thank you !

Currently, there is no plan to support the integrity signals from the OBI specification. Their definitions are available in the interface and the structure, but they are not handled in the IPs in this repository. While the specification outlines the signals to be used (reqpar, gntpar, rvalidpar, rreadypar, achk, rchk), the values of these signals are left to be specified at the platform level. Further, the behavior of the bus in an error state is not specified.

If you are interested in a fault-tolerant OBI implementation, feel free to look at relOBI:
