Suresh:

1) I believe all SI tools run the IBIS Golden Parser
(I have yet to find an exception). The GP runs
many checks of the IBIS model that is being input.

2) I don't think that IBIS provides a way to model
    a resistor array, but certain tools (SpecctraQuest
is the one I'm most familiar with) provides a way to
do it. Sorry, I'm not able to provide an example.

3) Many vendors do not know how to make correct
IBIS models or even understand the importance of
doing so. Fortunately, I believe this is slowly getting
better. The IBIS Quality Committee is working to
provide a spec and framework to standardized IBIS
model quality, and you can view their work in progress at
http://www.sisoft.com/ibis-quality. The best way to deal
with incorrect IBIS models is to contact the vendor of
the model and request a fix.
