Hi Tom and Muranyi,

Do you mean there is no difference for input receiver when generating ibis model? No matter it has or not terminator resistor on chip, I always can use the same model type like input?
Thanks for your guidance!

> If you use terminator you do not have an input model but a model of a resistor. An input model is what you want with the characteristic of the on die resistor embedded in one of the clamp 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?
