Scott,
I will go along with scary...but I'm not sure I would agree with the
accurate part. I have seen problems in Sigrity's software when using both
the Hspice and Generic outputs. If you have measured data in the time
domain that agrees to the results you get from a .tran run I would like to
see it. I will say, however, that the frequency domain results look pretty
good, but I'm not as impressed with the time domain results.
Nspice did a much better job in the time domain, and also was able to handle
the .ac run well too.
Regards,
Craig

Mick,
There are two solutions which I use:
1) Apache Nspice is an Hspice compatabible simulator that can
co-simulate with Touchstone S-parameter files.
http://www.apache-da.com/
2) Sigrity BroadBand Spice can convert Touchstone s-parameter files into
spice black boxes.
http://www.sigrity.com/
Both are scary accurate in both the frequency and time domain.
regards,
scott
