"capgen" error in Assura QRC (RCX)

bjbit

Hi all,

I work with the technology of IBM CMOS7RF on Cadence 5.1 (IC5141). Currently I am trying to extract parameters for a self-customized inductor.  By setting "ind" model in schemetic as a blackbox and ignoring mismatches, I go through LVS. Now an error happens in QRC as below.

========================================================================= 

*WARNING* at "capgen": x-tile size is not floating point number

*ERROR* at "capgen": capgen job quit due to process file errors.

 

quitting.

I cannot figure out what's wrong with "process file". I have installed Assura QRC package exactly as the document states. Any advices are appreciated.

Thanks. 

  • Hi bjbit

    My guess is that you are using redhat enterprise 4.x. You will need redhat enterprise 5.5 and above in order to use PVE package. : )  If it is not possible to find a machine with RHEL5.5 and above, you can also also use the slightly older EXT10.1.2 package. It should also resolve your problem. The history of QRC is as follows:

    a. Named as "rcx" and comes from Assura package
    b. Combined with cell level extractor and renamed as "QRC". Comes from EXT package.
    c. Packaged together with PVS in PVE package.

  • Hi Quek,

    Thanks for the advices. I will ask the manager to have a check.

     Hello,

    Sorry for my English.

    I have the same problem. I Upgrade EXT91 to EXT101 and now The QRC menu only give me  "Loading QRC menu..." and I ha ve the same warning about RCX UI.

    Does anyone has an idea?

    Thanks in advance

     

  • Hi Johjohn,

    As Quek advised, I have fixed this problem on PVE11 by using the newer version of Linux system. I am not sure about the compatibility of EXT10, but did EXT9 work for you? If so, probably you are having the same Linux issue. I guess you may try on another machine with newer version OS, and see what's going on. Anyway, I believe Quek can provide further advices.

    Regards,

  •  Hi bjbit.

    I'm working on Fedora 15. With EXT9, it works. But not with EXT10. The two install have the same configuration...

    I don't know why.

  • Hi bjbit

    Thanks. : )


    Hi Jon

    Would you please try upgrading to the latest version of Assura (41USR2_HF14) and latest version of EXT10.1 (10.1.3)? I think the earlier versions of EXT10.1 has this problem.

    Best regards
    Quek

  • Hi Quek,

    Thanks for your reply.

    I already made all the update. I'm well running Assura  41USR2_HF14 and the latest version of EXT10.1.3. But the problem still exist.

    If I running virtuoso layout whithout ASSURAHOME environmental variable configured, and if I click the qrc menu I have this message:

      *WARNING* QRC_HOME environmental variable is set but UI can't locate correct QRC installation. p, li { white-space: pre-wra

    In order to run UI in QRC compatibility mode you need to have QRC executables in your $PATH and QRC version should be 8.1 or greater.

    Check your QRC installation and environmental settings.

     

    And my environmental is configure like this:

     

    setenv QRC_HOME /softs/cadence/EXT101
    setenv PATH $QRC_HOME/bin:$PATH
    setenv PATH $QRC_HOME/tools/bin:$QRC_HOME/tools/extraction/bin:$PATH

     

    If I run  $QRC_HOME/tools/bin/qrc , it return nothing. But whith EXT9 it works with the same configuration.

     

     Best regards

  • Hi Jonjohn

    Would you get the path to the qrc executable if you enter the following in a terminal window?

    terminal>which qrc

    How about this?

    terminal>qrc -version

    Best regards
    Quek

  • Hi Quek,

     which qrc return: /softs/cadence/EXT101/tools/bin/qrc

    In fact I solved a part of the problem if I set OA_HOME to "/softs/cadence/IC614/share/oa", qrc don't work : the command "qrc -version" return nothing.

    But if I don't set the OA_HOME variable, it works...

    If I set OA_HOME to  "$QRC_HOME/share/oa, I can't run virtuoso. I have this error:

     /softs/cadence/IC614/tools/dfII/bin/64bit/virtuoso: /softs/cadence/IC614/tools/lib/64bit/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by /softs/cadence/EXT101/share/oa/lib/linux_rhel40_gcc44x_64/opt/liboaPlugIn.so)
    /softs/cadence/IC614/tools/dfII/bin/64bit/virtuoso: /softs/cadence/IC614/tools/lib/64bit/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by /softs/cadence/EXT101/share/oa/lib/linux_rhel40_gcc44x_64/opt/liboaCommon.so)

    Any idea?

     Best regards

     

  • Don't set OA_HOME. You should not have to - and if you do, you end up with these kind of potential compatibility headaches.

    If you don't set OA_HOME, each build can use the OA version it was shipped with, which is the right thing to do since that's what has been tested...

    Regards,

    Andrew.
