    STA considering IR drop Reply

    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.
