spectre version error

sabertooth

Hi everyone.

My issue is as follows:

----------------------------------------

1. I set up the cadence environment.

2. Now I fire up the workbench and enter a schematic using Virtuoso composer.

3.  I open ADE and when I run the simulation, I see the following error in CIW.

 *Error* The 'spectre' executable that you are using is an older version.
        Use MMSIM60 or later version of Spectre with this release.
        To check the spectre version, run 'spectre -W'.

 ----------------------------------------

Here are some useful messages from CIW just before this:

*WARNING* (icLic-3) Could not get license Analog_Design_Environment_L

*Error*   Failed to launch ViVA. There is a problem with the DFII
          installation hierarchy (Exit Code = 1).
          For further assistance, contact Cadence Customer Support
          with the diagnostic information available in the log file.
*Info*    Dumping diagnostic information ....
/usr/licensed/cadence-20060508/IC610.sun4v/tools.sun4v/dfII/bin/checkwavescan: wavescan: not found

  ----------------------------------------

I tried to check the path variable and even typed "Spectre -W/-V" which showed version 6.2 being in the path.

I do not understand why is the tool trying to access the older version of spectre even though, the first occurence of the executable in ($PATH, which is written above) refers to the higher version of 6.2.

I have the following questions:

  ----------------------------------------

1. Is the error "cannot load ViVA" related to cadence not finding the new spectre executable ?

2. How can I set the path within the CIW (will using SkillSetPath, not affect the other tools ?)

3. Is there a problem with my $PATH ?

 

Thanks in anticipation for your assistance with this !!

  • Hi Shoaib

     I noticed from your error message that $CDS_INST_DIR/tools/dfII/bin does not appear to be in your $PATH. Not sure how you are able to launch virtuoso without this in your $PATH.... Your cadence environment setup requires the following 2 paths:
            $CDS_INST_DIR/tools/bin
            $CDS_INST_DIR/tools/dfII/bin

    This should solve the earlier VIVA warnings and perhaps answers question #3.

    After fixing the $PATH, run "which virtuoso" and " virtuoso -W" to make sure it is picking up the correct virtuoso executable. Try the same for the spectre executable.

     - I don't know what role the viva issue this is playing in your spetre issue.

    - For question #2 above, I you trying to set the SKILL path or the unix $PATH?

    Assuming UNIX path:

     setShellEnvVar("PATH=<X>" ) ;;;where <X> = desired PATH
