Title: How to use multi CPU with ams
Post by Kamal on Oct 11^th, 2011, 1:34am

Hi all,

I would like to know how to use multi cpu with ams-ade.
I use UltraSim as solver.

Thanks,
K.

Kamal,
Versions?
There is a HIgh Performance options sub menu in the ADE setup menu, where you should be able to change the multi-threading settings (IC 5.1.41).

The only way I found to have a faster simulation is to decrease the accuracy of the simulation (Simulation->Options->FastSPICE(UltraSim)->Speed Option->Accuracy).

Kamal,

Version?

Select Setup --> High-Performance Simulation and a form pops up. Then select Turbo or APS, both having Multithreading options.

Hi Kamal,

What is your IC.5.1.41 version? And beside IC5.1.41, you need mmsim to enable High-performance simulation, otherwise that item is grey in Setup menu.

Hi Ywgo,

my IC version is 514USR5 & mmsim seems loaded:
*MMSIM (71) loaded*

IC5.1.41usr5 is far too old. Update to a recent version. And MMSIM7.x is quite old, too. Also a candidate for an update.

I was using IC5.1.41 on my system but now I want to upgrade the 6.1.3 version.
Please,can you give me some help about how to set the environment for doing so..
