Unable to run Monte-Carlo simulation on ADE-XL

rtyuy
rtyuy 1 month ago

Dear Friends,

I am using cadence virtuoso  (SUB VERSION: IC6.1.7-64b.500.19 (64-bit addresses)). Earlier Monte Carlo was running fine. but now when i run MC on ADEXL, it is showing following  error :

ADEXL-1921: failed to start new job after 3 attempts . Possible reasons could be

1. The machine selected in the current job set up policy is not reachable 

2. The cadence hierarchy is not detected, not installed properly, or not compatible on the machine selected in the current job set up policy.

3. Job start script /home/vlsi2/laxman/.temp_vlsi2/.cmddir0/runICRP17 is not found in the remote machine.

          Do you want to retry with the current set up? Selecting no will abort the current session.

Please  help me in finding the solution  of this problem.

i have  also  tried to change the license but it is still not working.

    I merged your posts (please read the forum guidelines - the pinned post at the top of each forum - as this tells you not to post duplicate posts in different forums; this will increase the chance of your post being ignored, not reduce it!)

    Anyway, what does your job policy look like? Can you run "virtuoso -nograph" on the machine it is launching to (the current machine if local)?

    Andrew Beckett , thanks for the response i am unable to get it .It will be very kind of you if you can help me to solve this issue with more details.

    in job policy setup distribution method is local and it was run fine with it ealier from last 2 years.

    do you mean  run  a command  "virtuoso -nograph " on the terminal ???

    In the terminal before you start Virtuoso (where you are trying to run cdsXvnc) either type:

    setenv LD_LIBRARY_PATH /home/install/IC617/tools.lnx86/lib/vnclibs:$LD_LIBRARY_PATH

    or:

    export LD_LIBRARY_PATH=/home/install/IC617/tools.lnx86/lib/vnclibs:$LD_LIBRARY_PATH

    depending on which shell you're using. If it complains about LD_LIBRARY_PATH not being defined, try the command with the part from the colon (:) onwards missing (e.g. setenv LD_LIBRARY_PATH /home/install/IC617/tools.lnx86/lib/vnclibs )

    Then in the same terminal, run cdsXvnc (and if that works - it will probably complain about the display not being set), then try "virtuoso -nograph" and see whether that starts (you'll need to type exit() to quit that).

    Ultimately you'd put the setenv/export in whatever startup script you use to set up your environment.

    cdsXvnc: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

    still the error occurs!

    My guess is that the /home/install/cshrc is resetting LD_LIBRARY_PATH - so perhaps you should set it after sourcing that file.

    Note, the right thing is to install the 32-bit compat package, but this may give you a workaround. Also, the really right thing is not to be using such an old and unsupported version of Virtuoso...

    Since you were starting csh earlier, you will need to use the "setenv" approach instead. export is for bash/ksh type shells.

    That's expected - as I said earlier:

    Andrew Beckett said:

    Then in the same terminal, run cdsXvnc (and if that works - it will probably complain about the display not being set), then try "virtuoso -nograph" and see whether that starts (you'll need to type exit() to quit that).

    Hopefully if that is all successful, then you'll be able to run simulations in ADE XL or Assembler.

    Since it is telling you that there's a problem and it created a log file, can you share the log file?
