Missing net and Cell Names-exporting gds2 from encounter , importing it in Caliber

asinghct
Hi, I am missing net as well as cell name information when I am exporting GDS2 from encounter and importing it into caliber (for RC+ coupling capacitance) extraction. Any suggestions on how to do it. Thanks Amit

  •  First of all, if this is a direct cut-n-paste of your script, you have the -phys parameter of saveNetlist spelled wrong.

    But, if all you want is RCs, You can get those right from Encounter.

    setExtractRCMode -coupled true
    extractRC
    rcOut -spf myDesign.spf

    The only part I'm not sure about is the last one - I don't know if that will give you dspf or not. (Most people use SPEF these days.)

    If you want sign-off quality extraction, you should run QRC, but that may require a bit more setup.
