AMS rolling back to the older version of ultrasim

01farhad10

I am seeing some strange behavior from the AMS simulator. I have changed the MMSIM version to 11.10 to use the most updated ultrasim simulator for multithread simulation. All the environment variables have been updated accordingly. However, when I try to simulate something the log files show that the older version of ultrasim (Version 7.1) is being used!

The interesting point is that when I am still in the same cadence session, if I use ADE for simulation it uses the newer version of ultrasim (Version 11.10). I am a little confused why the ADE can see the newer ultrasim but AMS doesn't? I appreciate any help in this respect.

Here is how my environment is set up:

$ echo $CDSHOME
/mscad/apps/Linux/cadence/IC61

$ echo $AMSHOME
/mscad/apps/Linux/cadence/IUS82

$ echo $IUSHOME
/mscad/apps/Linux/cadence/IUS82

$ echo $MMSIMHOME
/mscad/apps/Linux/cadence/MMSIM11.10

$ echo $LD_LIBRARY_PATH
/mscad/apps/Linux/cadence/MMSIM11.10/tools/lib:/mscad/apps/Linux/cadence/IUS82/tools/lib:/mscad/apps/Linux/cadence/IC61/tools/lib

$ echo $PATH
/mscad/apps/Linux/cadence/MMSIM11.10/tools/dfII/bin:/mscad/apps/Linux/cadence/MMSIM11.10/tools/bin:/mscad/apps/Linux/cadence/ASSURA410_FOR_614/tools/assura/bin:/mscad/apps/Linux/cadence/IUS82/tools/dfII/bin:/mscad/apps/Linux/cadence/IUS82/tools/bin:/mscad/apps/Linux/cadence/IC61/tools/dfII/bin:/mscad/apps/Linux/cadence/IC61/tools/bin  .....

     Multithreading of the ultrasim solver is supported in AMS - it's just the manual that's not caught up yet. There's a CCR (1016804) to get the documentation fixed.
