There is an IBIS Support page at http://www.eia.org/EIG/IBIS/support.htm
announcing the FREE Model Review Service:
IBIS Model Review: If you are developing an IBIS model and would like to
have your model reviewed, you may send your model to this address. This is a
confidential and FREE service provided by the IBIS Model Review committee
comprised of a number of EDA vendors. Feedback about the model will only
be passed to the requestor of this service. Model Review Service is intended
for use by IC MANUFACTURERS ONLY !(large or small).
The page has a hotlink for the email address. Hopefully IC vendors are using
repeatable processes to develop IBIS models, so only a small sampling submitted
for review could really pay off.
