Re: Aurora 8b10b UFC problem

tx_data is 128bits
ufc_tx_ms always 3'b111 means ufc_data is 16byte

Re: Aurora 8b10b UFC problem

Can you confirm if warn_cc is asserted when you are sending UFC message?

Thank you for your replay. I am sure the warn_cc is 1'b0.

If you can reproduce this in simulation, please share the simulation log (.wlf) by capturing all signals.
