Hi S Shankar—
I would suggest you contact your local Mentor customer support representative
who can help you work through the process.
Thanks.

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?
Thank You,
S Shankar

Hi S Shankar--
If you want to predict an accurate BER at these levels it is recommended that
you simulate using the worst-case bit stream specific to a channel. That bit
sequence will vary based on the characteristics of the channel, and of course
should include the appropriate encoding (like 8b10b).

Hi,
Could some one guide me what should be the PRBS pattern for achieving BER <
1e-16 ?
Also how to calculate the required no. of bits for the PRBS pattern as per the
require BER?
Thank You
S Shankar
