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:
*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 !!
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
