William,
If you can get SPICE models from the vendor then you can probably use
s2ibis3 (or similar tool) to make an IBIS file. If you can get parts of
(preferably) known process corner then you can pay someone like Tom
Dagostino to measure the part and make an IBIS file from that.=20
Beyond that, it might be sufficient to take a good guess at the
characteristics of the part and grab pin models from other parts of the
same or similar technology. For example, if you know that the part has
DDR interface, you can get a DDR I/O buffer model from a variety of
other IBIS files. You can make a pin list from the datasheet of the part
to be modeled.
Good luck,
Weston

Hello all,
=20
When a chip vendor doesn't supply an ibis model, what resources have
been the most
successful/efficient for creating/supplying the missing models?
=20
Thanks.
