case average IR drop is generated considering a PVT point which is
different from both worst and best case PVT points for timing
analysis (I use both corners to check hold and setup violations).
Should I run IR drop analysis
same PVT points I will use for STA?
PVT point for worst IR drop and so run STA considering this PVT
PVT point for worst IR drop but using the PVT point for worst/best
case timing when running STA?
If I consider the PVT point for
worst case voltage drop I won't check the worst/best case for STA,
and checking worst/best case for STA I won't check for worst case for
voltage drop. At the same time, if I use worst case for IR drop and
worst/best case for STA I"m considering an invalid PVT point.
So, what is the recommended
methodology to run a safe timing analysis considering IR
