Error about Environment Variable settings

wgtkan

Hello,

After doing an update to the new pdk I get the following error. I think It comes from my .csinit file. It is asking about the EV variable of GF_PDK_HOME not being set.

And many other errors that come from the .cdsinit.

Please see attached.

Thank you always.

    look at your .cdsinit above - you do not(!!) issue a setShellEnvVar(..) - you do

    if(gfPdkHome = getShellEnvVar("GF_PDK_HOME=/home/grps/ef-test/GLF8HP/130HPSIGE-8HP/") then...

    it is supposed to be:

    setShellEnvVar("GF_PDK_HOME=/home/grps/ef-test/GLF8HP/130HPSIGE-8HP/")
    if(gfPdkHome = getShellEnvVar("GF_PDK_HOME") then
    ...

    And better yet you set it in the bash ever before you launch virtuoso

    What is the alternative in .cdsenv? How do we write the same command in .cdsenv?

  • in reply to wgtkan

    There isn't an alternative to do this in the .cdsenv file, and there is no "command" you can use in the .cdsenv file. Mainly because it doesn't make sense because:

    • .cdsenv is a file containing the names and values of Cadence-specific variables. This is not "code" (it's not a programming language), and these variables are not UNIX environment variables - they are settings specifically for Cadence tools (in particular Virtuoso)
    • .cdsinit is a file containing SKILL code executed at startup. Because it's written using a programming language, you can perform a wide range of different operations, including interacting with UNIX environment variables as we've shown above.

    Regards,

    Andrew.

    I see. 

    So before launching a virtuso I have to give either of the following commands at the unix prompt?

    Type this at the working directory

    1. For bash
    export GF_PDK_HOME=/home/grps/ef-test/GLF8HP/130HPSIGE-8HP/V1.8_1.1HP

    2. For csh

    setenv GF_PDK_HOME /home/grps/ef-test/GLF8HP/130HPSIGE-8HP/V1.8_1.1HP

    Thank you so much Andrew.

    Of course, you could also set it wherever you're setting up the path for the software, the environment variables for the licensing and so on. That might be done in your ~/.cshrc, ~/.login or ~/.bashrc, or you might be using modules or something similar to configure your UNIX environment. You don't necessarily need to type it each time, and you could (as both Max and I have said) put a setShellEnvVar() call in your .cdsinit to set the environment variable there.

    Regards,

    Andrew.
