Models & EDA Vendors

I've recently seen a demo for MGC's ICX tools (Including Tau for timing
verification). There software uses native IBIS models for timing and
signal integrity estimations on the fly, and simulation.

ICX mentions a library of 10K parts, as a first tier, afterwards there
are two-tiers which cost the end-user progressively more for ICX to develop
ibis models.

ICX mentions that they are working with ic vendors providing them with
tools which would allow them to develop accurate ibis models themselves.
I'd like some feedback from anyone (ICX users, IC Vendors, etc..) who
have worked with ICX on developing IBIS models.

Secondly, we've found that many of the parts we'd like to simulate with
don't exist in their library. While it's expected that newer components/
technologies might not have models, some of the models that are lacking
are typical everyday parts/technologies. What's the preferred approach
to obtaining and verifying accuracy of these parts?

Lastly, IBIS is a great idea, and the people behind the scenes really
deserve a round of applause. However, I'm interested in people's opinions
on how widely available _accurate_ models are from component vendors.

Thanks for your feedback,

Chuck
