Akhilesh,

Thanks for your question.  One leading idea you might find useful is
that the *design* may switch at one particular point, but one million
typical parts at the same fixed voltage and temperature conditions do
not all switch at exactly the same voltage point.  The expected range of
variation would likely come either from the silicon manufacturer or from
the relevant industry specification.

Subject: [IBIS-Users] Extraction of Vinh+ and vinh-

Hello Experts,

  I have one query regarding vinh+ and vih-. According to IBIS spec we
can
define it by following way.

                           TYP       MIN        MAX
Vinh+                     2.0        NA         NA  
Vinh-                     1.6        NA         NA 
Vinl+                     1.1        NA         NA 
Vinl-                     0.6        NA         NA 

  How we can extract vih+ and vinh- at one process, voltage and temp. In
my
view design switch at one point. How I can extract two values.

Regards
Akhilesh
