Problem with LVS, DRC

archive
I am using Cadence 5.141 and I have licenses for LVS, DRC (Assura_LVS, Assura_DRC). However LVS and DRC checks dont seem to work - (LVS and DRC options are not greyed out in the menu options); they start working but then complain of a license failure (no feature for Assura_DV_Design_rule_checker). Can anyone suggest what is going on here? Attached is the license.log file. Best regards and thanks in advance, -Vijay

  • Vijay,

    It sounds as if you're trying to run Diva LVS (the license feature is the one you're mentioning as it failing to find), rather than Assura LVS. Diva LVS is under Verify->LVS (Diva DRC is Verify->DRC). For Assura, it would be under an Assura menu.

    To get the Assura menu, you need to have the appropriate ASSURA stream installed, $ASSURAHOME set to the root of the Assura installation, and $ASSURAHOME/tools/bin in the path (I think that's it, from memory).

    Regards,

    Andrew.

  • Hi Andrew, Thanks for the clarification and that worked. I was wondering if you could provide the location of any tutorial or a user manual that comes with the installation for Assura. Thank you, -Vijay

  • Vijay,

    All Cadence releases come with documentation - use cdnshelp if a newer release, or cdsdoc if an older release to find it. With both you can open documentation from another stream - the documentation is in <streamInstallationDir>/doc - and even if you can't run the documentation system for whatever reason, you should find PDF files too you can look at. For example $ASSURAHOME/doc/assurauser/assurauser.pdf

    Regards,

    Andrew.

  •  Hi,

    I want to run DRC using DIVA.

    I am getting the following error when I attempt a Verify->DRC in Virtuoso 6.1.4:

    *WARNING* No DRC (Assura_DV_design_rule_checker) or DRC (312) license is available

    *WARNING* Verification program terminated

     

     

     Please provide inputs.

  • Please check if you have valid licenses for DIVA or file a service request and get it checked with Customer Support.
