Subject: IBIS Voltage Sweep question
Hello,
I have a question about performing voltage sweeps for pullup, pulldown, etc,
when looking at minimum and maximum conditions. Below is an excerpt from the
IBIS Modeling Cookbook for IBIS version 4.0, page 16:
[A text on a page Description automatically generated]
While this 9.9V sweep range covers the minimum voltage, I don't think it would
cover the maximum voltage condition, which would range from -3.6V to 7.2V. Does
that mean that this range needs to be 10.8V for all sweeps, including the
typical and minimum condition? Otherwise I don't think you have all the data
you need, since the step size for the sweeps shouldn't change from voltage to
voltage, or at least that is my understanding of the IBIS standard.
Thanks!
Andrew
