Hi Patrick,

Thank you for the clear answer. Makes total sense to skip the post-synthesis simulation then for my purpose. I am in fact using the OSVVM AXI Stream components which have tpd. I have a design with mainly several axi streams, so I am following the testcase OsvvmLibraries/AXI4/AxiStream/TestCases/TbStream_SendGetDemo1.vhd.

I need to play around with tready (for a receiver), when to assert it (before or after tvalid). I played with RECEIVE_READY_DELAY_CYCLES and RECEIVE_READY_BEFORE_VALID but I noticed tready is asserted at the beginning of the simulation no matter what. I found this post . Can that behavior be changed?

Thanks for the help.
