Eric,
No. The reason is because the difference between a terminator and an input is
that the first one just terminates, and doesn't have Vinh and Vinl. If you
want to make an input model that also has an on-die terminator, you have to
put the terminator's characteristics into one or the other clamp IV curves.

> Can I choose "terminator" as my [model type] if I have an input receiver with on die terminator? If true, can I also use subparameters [Vinh] and [Vinl] to define input threshold voltage? If true, then what is the meaning of "...but has no digital logic thresholds..." for terminator model in IBIS spec. 3.2 version, page20?
