From the standpoint of accuracy, SPICE models (if you can get them) are
nearly always to be preferred to IBIS models (if you can get them). I
frequently
try to get both so I can compare results; if the comparison shows small
differences, IBIS models usually run faster, so would be preferred once
you
are assured of their accuracy.
Let me suggest that you visit and read the FAQ found at:
www.eigroup.org/ibis/faq.htm
While your question is not addressed directly there, you will find a lot
of background info that will help you understand the difference. That
statement assumes you are a user of SPICE already, of course.
