ELC : Simulation status : FAIL during db_spice

Hemal93

When I execute step 2 in ELC means spice simulation then find simulation status fail for all #ID as shown below.


Command : db_spice -s spectre -p typical -keep_log -keep_wave

I have checked both the directories. 
----->There is no any warning or error in encounterlc.log/.....

----->But in encounterlc.work/......./typical_D0005_tr.lis has some warnnings like,

Can you help to solve this problem?
Thanks in advance.....

    My guess is that you have $LD_LIBRARY_PATH set to include this directory from your "SPB" installation - probably not needed for SPB, and certainly not needed for spectre. Can you do "unsetenv LD_LIBRARY_PATH" (if using csh) or "unset LD_LIBRARY_PATH" (if using ksh/bash/sh) and see if that helps (before running ELC).

    Andrew.

  • Hemal93
    First of all thanks ..... I have removed $LD_LIBRARY_PATH by unset as you said. But it is also not working. Same result coming with same warnings.
  • Andrew Beckett

    OK, that doesn't make sense - I can't see how it can pick up a shared library from the SPB installation without knowing something about where to find it. 

    So, can you do the following (in the terminal where you've unset things) and post the results:

    echo $LD_LIBRARY_PATH
    echo $PATH
    which spectre

    (it's possible you have spectre as a wrapper script which is setting LD_LIBRARY_PATH).

    Regards,

    Andrew.

    Terminal gives these result.....

  • Andrew Beckett

    Hi Hemal,

    Can you check in your /home/Cadence_tools/MMSIM111ISR_lnx86 installation - is there a link called "tools" there? If not, the path to the MMSIM installation will not be working, and that would explain the problem. You either need to add a link from tools.lnx86 to tools in that directory, or make sure your path has:

    /home/Cadence_tools/MMSIM111ISR_lnx86/tools.lnx86/bin

    in it (at the beginning - before the SPB path). I'd forgotten that the SPB installations also have spectre included. You have it at the end of your UNIX path, but because the MMSIM installation isn't correct, it is not finding it.

    Regards,

    Andrew.

  • Hemal93

    Thanks Andrew,

    Its working . Actually there was not a link for tools at that path.
    Now it is working.

    Thanks again,
    Hemal
