Mistakes in IBIS models are now a dime a dozen? When did the price go up?

Hi Louis:
The spec and your initial example are correct. Mistakes in IBIS models are
a dime a dozen, unfortunately. As a recent thread discussed, many models do
not appear to be validated in simulators before they're released, and a lot
of models have obvious syntactical errors.
Best Regards,
Bill Hargin
