Subject: [IBIS-Users] IBIS Model generation of I/O buffer with over voltate protection

Hi,
We would like to know how to generate the IBIS model when the output
driver has an over voltage protection circuit; means when the pad
voltage rises above VCC, then the PMOS pull-up will be turned-off by
tracking the pad voltage . How to control or specify the sweep voltage
for the pull-up curve, or do we need to turn -off the over voltage
protection circuit for IBIS generation.
Thanks in advance,
Ranjan
