Unable to run Monte-Carlo simulation on ADE-XL

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

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 ???

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...

Andrew

Andrew Beckett if do source /home/install/cshrc

i move to 

Welcome to Cadence Tools Suite

[user@eeiitj123 ~/parm_65phd]$ export LD_LIBRARY_PATH=/home/install/IC617/tools.lnx86/lib/vnclibs:$LD_LIBRARY_PATH
export: Command not found.

(I understand that i am using older version but i have no  other option as i told earlier  :(  )
 

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

Andrew

 Andrew Beckett ,  i have done

[user@eeiitj123 ~/parm_65phd]$ setenv LD_LIBRARY_PATH /home/install/IC617/tools.lnx86/lib/vnclibs:$LD_LIBRARY_PATH
[user@eeiitj123 ~/parm_65phd]$ setenv LD_LIBRARY_PATH /home/install/IC617/tools.lnx86/lib/vnclibs

Fatal server error:

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.

 Andrew Beckett  again same problem

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

it is written as :

But when i checked the font tried to install  xorg-x11-fonts-75dpi xorg-x11-fonts-100dpi xorg-x11-fonts-misc, following output is achieved

Package xorg-x11-fonts-75dpi-7.5-9.el7.noarch already installed and latest version
Package xorg-x11-fonts-100dpi-7.5-9.el7.noarch already installed and latest version
Package xorg-x11-fonts-misc-7.5-9.el7.noarch already installed and latest version

Can you try this:

df -kT /usr/share
ls -li /usr/share/X11/fonts/

I'm particularly interested in the inode number - there's a possibility (we've seen this elsewhere) that it's using large inode numbers, higher than can be read with a 32-bit executable. If it's this, there's little that can be done other than moving to IC6.1.8 (recent ISR).

At this stage I'm clutching at straws - and I cannot realistically spend more time trying to debug (over the forums) an issue with an unsupported release when the solution is to move to a newer version.

See also this article (check the directories to see what is installed).

i have also installed 32 bit compat package now

I have no idea in that case. All looks OK to me. Yes, it's an xfs file system, but the inodes appear to be not too large.

Andrew

thank you ,

i have also installed 32 bit compat package

Is anything can be done  with e 32-bit compat package, if possible ?

i  just want to tell one thing that there is another machine in our college  in which same cadence version is installed , however Monte carlo runs fine there, i dont know what caused in my machine :(
