Does Assura version affect QRC

Jsierra
Jsierra over 15 years ago

 Hi,
I'm trying to setup QRC and I've followed the manual by adding the following:

In the csh file:

setpath = ($EXT_8_1_4/tools/bin $path)

In the cds file:

setenv QRC_HOME usr/cds/ext-8.1.4

 

However QRC is not showing up in the menu on the virtuoso layout editor.


I'm using IC 5.1.41 latest subversion, Assura 3.1.5

Could this be due to the version of assura I am using?



Thanks,
Jon

     Hi Jsierra

    Here are the requirements:
    a. "Assura" menu only needs "ASSURAHOME" variable to be defined in cshrc file

    b. "QRC" menu needs the following:
    - "QRC_HOME" variable to be defined in cshrc file
    - EXT81 and above
    - Path should include $QRC_HOME/tools/bin
    - Min version of Assura needed for QRC menu is 3.2. If not, ASSURAHOME variable should not be set
    - IC5141.500.6.10 and above

    The only workaround for your situation is to include the following line in your cshrc file and access QRC form through "Assura->Run RCX".

    setenv QRC_ENABLE_EXTRACTION
    (No value is needed for the above variable)

    The form title should now read "QRC Parasitic Extraction Run Form" instead of "Assura Parasitic Extraction Form". You can also find more info on QRC menu setup in Appendix F of QRC user guide located at $QRC_HOME/doc/qrcxUser/qrcxUser.pdf.

    AV317 is really too outdated. If possible, please upgrade to AV41HF3.

    Best regards
    Quek
