Re: Modeling question

Jerry,
I think the problem is that the "pullup" part of the model is always
turned on. (IBIS simulators expect it to turn off during the falling
edge and this is probably happening by default in your model)

I have two ideas to try:

1) Remove the pullup, make the model, and then put the pullup in by hand
as a part of the shunt curve.

2) Make the model as regular but do not make a "pull-up" measurement (or
set it all to zero) and once again let the pull-up curve reside in the
shunt part of the model.
