I have a question,
I am having a lot of trouble with this error when doing signal integrity
simulations of some I/O buffers with package models and T models for
tranmission lines as well as some loading. I am using HSPICE2000 version. I
will change to U and then W models for more accuracy.
I would like to get a fresh look at what are the best options to use when
having this problem.
In the past, I have had the same problem with TSMC 0.18um models due to some
negative-mos conductances?
Is there anyone out there experiencing the same problem and if so any ideas
on how to find the right set of options so that I don't get these erros?
Once again this is what I am simulating:
I/O buffer + Package model + Tmodel + capacitive loading
I appreciate any comments.
Regards
Elias
