layerset(2) issues

rdohanyos99

I have several layersets setup. They are stored in .cadence/dfII/layerSets/techo/ . When i load up virtuoso (ic 616) it loads them automatically. The issue I'm having is that they get loaded 2x and I don't understand why. I get 2 of each, one with the proper name and a second with (2) following it.

How can I stop it from loading the 2nd time.

Thanks!

Rob

  • Rob,

    I expect you have an environment variable that means that the directory containing the .cadence directory is appearing more than once in the setup.loc. For example, in my working directory, I have:

    UNIX> ls .cadence/dfII/layerSets/gpdk090/
    Blah.layerSet      implants.layerSet  newAll.layerSet
    M1only.layerSet    metals.layerSet

    and normally if I do "cdswhich -all .cadence/dfII/layerSets" I get:

    Info (cdswhich): '.cadence/dfII/layerSets' found at:
            ./.cadence/dfII/layerSets

    If I do:

    UNIX> setenv CDS_PROJECT $PWD
    UNIX> cdswhich -all .cadence/dfII/layerSets
    Info (cdswhich): '.cadence/dfII/layerSets' found at:
            ./.cadence/dfII/layerSets
            /export/home/myusername/demos/IC612_Whatsnew/design/.cadence/dfII/layerSets

    I then get the duplicates showing up in the palette. It could be that if you start from your home directory this would happen anyway (because both $HOME and "." are in the setup.loc), or if you have (say) $CDS_WORKAREA, $CDS_SEARCHDIR, $CDS_SITE set - use "cdswhich -all" as shown above to see where it is looking - and check the contents of the setup.loc that Virtuoso is using - best way is to do:

    `cds_root virtuoso`/tools/bin/cdswhich setup.loc

    (the cds_root bit is to ensure that you are finding the setup.loc that Virtuoso would find - because otherwise if you just run "cdswhich" it might find the setup.loc from the MMSIM installation - which should be the same anyway by default, but it's more a case of if it has been customized).

    Regards,

    Andrew.
