FreeLists / si-list / [SI-LIST] about ibis model validation

[zheng qi <qzheng.hb@xxxxxxxxx>]

I am doing idtfct3807 ibis model validation in Hspice .  This ibis
model works well in sq and quite fit to it's hspice result. but when
using this ibis model in hspice. the result was totally wrong. for example
the output voltage reaches 100v. by tuning the options such as timestep
fwf_tune etc. I found the problem maybe occures in the process of
interacting
of VI and VT data . Because of not knowing the exactly data interaction
process.  How to fix this . Adjust IBIS model itself or others???
Below is part of the spice deck
b_output nd_pu nd_pd output in1
+ file='43807.ibs'
+ model='outbuf'
+ type = xxx
+ xv_pu=nd_state_pu  xv_pd=nd_state_pd
*+ interpol=1
*+ fwf_tune=xxx  rwf_tune=xxx
*+ pu_scal=1.0
*+ pd_scal=1.0
