The same can also be true for SPICE models.

Well, not necessarily when the vendor's IBIS model is flawed.
This can occur in such a way that the error doesn't turn up
until a board is routed and timed, or even until a prototype
is built and tested. Better no model at all (which causes
one sig int engineer to work on building one) than one which
causes a dozen designers to propagate an error.
Perhaps vendors should be prohibited from using the IBIS name
unless they certify the accuracy of their model or attest
to it with measurements. Until then, Caveat Emptor.
