Hi, Ambrish;
I am not sure if your suggestion of shorting redriver Rx ibis output pin to the
redriver Tx ibis input pin in spice simulations will work because in spice
simulations
1. legacy Tx ibis model is driven by input signal threshold crossing
events. That's not how a redriver Tx half is driven by input signal.
2. legacy Rx ibis model output is a digital signal of 1's and 0's
(hopefully I am correct here). That's not what redriver Rx half outputs.
Due to the uncertainties in redriver model behavior in non-AMI simulations, I
prefer to keep my redriver BIRD separate from Walter's repeater BIRD, at least
for now.
Regards,
Fangyi
