bi,

Use the "Polarity" sub-parameter of the [Model] keyword.

I have an inver output PAD( crystal oscillator), the polarity of input
and output is invert, Could IBIS model can describe this kind of buffer?
And if it can, how to do it? The output waveforms will be different with
normal.(such as pull down curve shoud look like pull up curve)?

Thanks a lot!!
