Hi Friends,
Can I please ask a question concerning simulation CPU cores usage.
When I was using ADS on a Windows PC for simulation, the software will automatically use all the cores and the CPU usage is close to 95%.
However, now I am using CADENCE IC 617 and MMSIM151 on a Linux machine with 10 cores CPU (20 threads). The simulation setup is like this:
ADE L --> Setup --> High-Performance Simulation Options. Then I click APS. choose Error Preset: DO not override; Use ++aps; Multi_Threading Manual #Threads: 20 (0-19)
But when I try to simulate, the CPU usage is about 40%. Though this is way better when I chose Spectre instead of APS to simulate(that's 5% CPU usage, due to only one thread is working.)
Can anyone help me? How can I setup the software to use all the CPU power to speed up the simulation?
Thanks
Allen.
