Occasional ContributorHello,
I tried simulating (in ModelSim 10.6d) using the native PHY PCS direct with the same parameter as in ug-20211 and the same prbs_top, prbs_gen, prbs_ver_pipelined from the hssi_prbs example.
I tried simulating the same steps as in hssi_prbs.c (reset, serial loopback, and unpause tx & rx). But in the simulator itself, the data received is not the same. (comparing prbs_din with prbs_dout). Is there any special instructions or configurations or technique that I need to implement in order to use PCS direct? Can someone help me with this?
