  • Hi Eng,

    By GPS I meant, Only Placing the data and Not the routing part.

    You are correct that RC factors should be calculated with QX spef but that is to corelate before and after route.

    My question was, That I have a database which is timing clean in RTL compiler (Cadence Logical synthesis tool) but has violations when I place it using GPS(Cadence encounter), so can I use some RC scaling factors in Rtl compiler PLE flow so as to correlate my Timing results before placement and after placement.

    Regards,
    Vikas
