[SI-LIST] IBIS Model Quality (or lack thereof)

Hi all,

We have been doing a lot of comparisons between IBIS and HSpice models
lately, with a lot of less-than-satisfactory results.

I have an open question for the semiconductor suppliers among us:

What testing is performed after an IBIS model is created, to ensure that the
completed model behaves as expected?  I'm interested in responses from
vendors that actually SIMULATE the IBIS model before distributing it for
customer use.  It looks to me as though many of the models I've received
were never used in a simulation before being released ...  and, as a
potential customer, I find that quite disheartening.

So the question is - what processes are being used to test IBIS models and
ensure they function properly before their release to customers?

As always, replies both on and off the list are greatly appreciated.

Todd.
