cadence ic613 with assura32: warning about environment variable

iamlearning

Hello all,

I installed cadence ic613 and assura32 for the first time. When I open the Layout Editor Window from the CIW, a warning pops up in my CDS.log file informing that, it could not find the ...../ic613/tools.lnx86/dfII/etc/tools/assura directory to load environment variables. Anyone please write me what does it mean. How could I fix it ?

Thank you ...

    Seems no one faced this warning like me. However, my product versions are:

    virtuoso -V

    @(#)$CDS: virtuoso version 6.1.3 09/08/2008 02:56 (cic612lnx) $              and

    assura -V

    @(#)$CDS: assura version av3.2:Production:dfII6.1.3:IC6.1.3.500.4 12/21/08 16:47 (sfrh327) $

    Is there any possibility of version mismatching issue ?

    Hi iamlearning

    Would you please upload your CDS.log file? Please do not cut and paste. Use the file upload function. Actually the outputs of "virtuoso -W" and "assura -W" would in general be more helpful as they provide the specific versions which you are using.

    Best regards

    Thank you Quek for your reply. I uploaded my log file to  http://www.4shared.com/get/291516911/6a20458e/CDS.html . And other information are:

    virtuoso -W

    sub-version IC6.1.3.1    and

    assura -W

    sub-version 3.2 USR2

    Please, check for the warning regarding the assura environment variables. Thank you,

    Regards

     \w *WARNING* Cannot find /usr/local2/cadence/ic613/tools.lnx86/dfII/etc/tools/assura directory to load environment variables

    In CIW type getShellEnvVar("ASSURAHOME"), make sure it is set to the correct path, which seems to be /usr/local/cadence/assura32/tools.lnx86/assura/.

    Thank you tkan for your suggestion. I added the following lines in my .cshrc file for assura:

    setenv ASSURAHOME /usr/local/cadence/assura32
    set path = ($path $ASSURAHOME/tools/bin $ASSURAHOME/tools/dfII/bin $ASSURAHOME/tools/assura/bin)
    set LD_LIBRARY_PATH = ($ASSURAHOME/tools/lib)
    setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:$ASSURAHOME/tools/assura/lib

    Would you please tell me whether I have to modify anything in the .cshrc file?

    Thank You,

    Regards

     he means all you need to add to your .cshrc is

    setenv ASSURAHOME /usr/local/cadence/assura32

    set path = ($path $ASSURAHOME/tools/assura/bin)

    Hi iamlearning

    Thank you for the file. : )

    To upload a file, please follow the steps below:
    a. Press "Reply" button
    b. Select "Options" tab
    c. Use "Add/Update" button under "File attachment"

    It is not really a good idea to use "$ASSURAHOME/tools/assura/bin" in the cshrc file as some wrappers might be bypassed. Please use the following instead:

    set assuraPath=($ASSURAHOME/bin)
    set path = ($assuraPath $path)

    The warning is actually quite harmless and can be safely ignored. It is most likely due to the pdk initialization scripts. My guess is that there is a "envSetVal" cmd in the libInit.il file (or a related file) which is attempting to load a non-existent settting. We can of course trace through the files to find out the cause of the problem but I guess that might be quite unnecessary since the warning is quite harmless anyway. You can go to the pdk technology directory and start from the libInit.il file. Check all the envSetVal cmd and see if you can any anything suspicious.

    Best regards
    Quek
