RE: [IBIS-Users] Need clarification

Hi, Ambrish,

Did you mean to say:

Pullup = total_current - power_clamp - gnd_clamp
Pulldown = total_current - power_clamp - gnd_clamp

Hi,
Both the pull-up and pull-down VI curves subtract the power and ground
clamp curves respectively to obtain the VI table in s2ibis2 and s2ibis3.
This is done only for models with enable inputs.
Hope that helps.
