Hi Patrick, Thanks for the valuable inputs. I have few more doubts as, i am using Hyperlynx 8.2.1, as you suggested i can only select PRBS pattern or the 8B/10B pattern in the Hyperlynx. So could you clarify me that, do i have to simulate the net only with 8B/10B or how should i include the 8B/10B coding in the simulation?
