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
