QRC Extraction issue

MadapusiSriniv

Hello colleagues,

I am trying to do an SSTA Timing extraction by encounter using tech files generated by ext132 .

So I perform "setExtractRCmode -effortLevel signoff -engine postRoute"

and I have the following issue

"QRC extraction failed because the executable 'qrc' could not be found. Correct your environment PATH setting and run again. "

Can someone please help me with this?

thanks

  • Hi Divya,

    The '-effortLevel signoff' option when used , invokes standalone Quantus QRC parasitic extractor software from Cadence. So you need to acquire the correct package licence for QuantusQRC  before you run extraction with signoff accuracy. Check your installation directory and source/set the correct env variables. May look like something like this:-

    source /pkg/cadence-ext-/13.20.451/i686-linux/env/cshrc
    setenv PATH /pkg/cadence-ext-/13.20.451/i686-linux/pkgbin:/pkg/cadence-ext-/13.20.451/i686-linux/bin:${PATH}.......

    Thanks,

    JK

  • Thankyou , do you know what is the name of the package I need for quantus? Is it an additional licence to Usual Iqrc/tqrc extraction ? If so , please can you tell me how to check it.

  • Yes. Quantus QRC is a separate package unlike the TQRC and IQRC engines which are invoked when you give -effortLevel medium or high.

    All cadence packages are installed in the root. So check your root directory for a pkg folder and inside that check for 'cadence-ext-' folder this is where the Quantus is installed. If it is not , then you may have contact your  admin.

    Try:  downloads.cadence.com

  • Thankyou,

    Are these packages suffice?

    Virtuoso® QRC Extraction - XL QRCX300 EXT141
    Virtuoso® Advanced Analysis GXL option QRCX310 EXT141
    Cadence® QRC Display Technology GXL Option QRCX330 EXT141
    Cadence® QRC Advanced Modeling20 GXL Option QRCX520 EXT141

    These are the ones I have currently.

    Thanks
