Hi All

I have IBIS model for a device operating at 3.3v , The model of
the same device for 5V is not
availible .My quection is , Since the technology remains same by
extending the Pull up .pulldn
pwrclamp and Gnd clamp Curves AND by Changing the Voltage range
(also threshold) Can we make IBIS models ??

Does the change in device voltage will have Large Variation in C_comp
??

Instead of Going for Equivalent 5v device , this should be the better
choice .
please Correct me If I my approach is Wrong

Thank you

SUDHEER
