["Dima Smolyansky" <Dima.Smolyansky@xxxxxxxxxxxxxx>]

Hello,

I think one key issue here is the time it takes to generate the eye. In our
IConnect software, an CJTPAT eye can be generated based on S21 or TDT (time
domain transmission data) in a manner of seconds. Effects of crosstalk can
be easily measured and added to the eye, and the eye opening/jitter 
information can be measured as well. How long does it take to do this in 
simulator? Hours?

Thanks,
