[SI-LIST] Basic IBIS I/V curve question

Hello list members,
Here's a rather basic question but I would appreciate your comments.
I've been simulating a CMOS buffer with different I/V curves =
(min,max,typ).
There can be easily seen that the buffer gets slower as the operating =
voltage is reduced.
In this design the operating voltage is never going to be as low as it =
is in the I/V min curve.
Actually the guaranteed minimum operating voltage is much closer to the =
typical I/V curve.
It is a bit unclear to me whether the operating voltage is the only =
thing that is changed as the three different I/V curves are =
generated/measured for the IBIS model.
Is there any reason, in this case, why should the min. I/V curve be =
included in this simulation?
Are IBIS only simulators capable of performing simulations with other =
operating voltages than what is available in the I/V curves? If so, how =
it is done?
Br,
Marko :-)
