Hi Jim,

Are there any updates on this?

I am also looking to not having tready asserted by the receiver at the beginning, but instead using RECEIVE_READY_BEFORE_VALID=FALSE and RECEIVE_READY_DELAY_CYCLES to assert tready after tvalid is asserted. See here https://ibb.co/jZVyy9ZH
Thank you.

ps: Do you have a new and updated documentation for the…[Read more]

What about running the simulation in vivado? I’m mostly interested in post synthesis functional simulation as I have a vhdl module currently that works fine in behavioral simulation and works…[Read more]

What platform do you use?
Linux, macOS, Windows, MSYS2, …?

Unfortunately, the made there own GHW reader as far as I know. So it could be failing as well.
