Important IBIS question to all

Text item: Text_1

Hi IBIS people,

In discussing the issue of non-monotonic curves, I realized that there is an
unspoken assumption present that needs clarification. I would like to ask
everyone to reply if possible to the following question:

How do you use the POWER/GND clamp and pullup/down curves in your simulations?

 a) summing method, or
 b) exclusive method

Explanation:

a) By the summing method I mean that the VI curve in the clamp section is added
to the VI curve in the pullup/down section for the ON condition. For the OFF
(3-stated) condition, only the clamp curves are used.

b) By the exclusive method I mean that the clamp curves are strictly used for
the 3-state condition, and the pullup/down curves are strictly used for the ON
condition without adding in the currents from the clamp sections.

I appreciate your responses,
