Hello,
Worst
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
considering:
the
same PVT points I will use for STA?
the
PVT point for worst IR drop and so run STA considering this PVT
point?
the
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
drop?
Regards,
Cristiano.
