Eye diagram before + after rx equalisation

Question asked by pjs on Mar 2, 2018

I'm trying to examine the eye diagram of a signal before and after the rx equalisation. The main reason is to ensure that  we meet the minimum eye opening at the receive pins as specified in the datasheet. This is usually specified before the receiver equalisation is applied and so I'm trying to confirm that with our channel design that this will be possible.

 

I can't see how to do this in Hyperlynx as I'm finding that regardless of where I place the probes on the transmission line, the equalisation parameters in the receiver always affect the eye very substantially.

 

Is there a way in the AMI Channel tool to see what the eye diagram looks like before the Rx equalisation is applied?

 

Thanks
