Hi Clinton,
Thank you for your reply.
Unfortunately the customer does not have the equipment to probe the eye diagram or the clock signal. There are only the SRIO switches that have the PRBS test patterns generation and detection capability.
The SRIO SERDES configuration registers have never been checked after the tests are running. I am going to ask them whether they can provide it.
They want to consume time and labor only for the tests with correct configuration and procedure, hence have not tried Gunter's test procedure. Can you predicate that Gunter's procedure is reliable?
Best regards,
Daisuke
