How do run Spectre on Multiple CPU?

[Juvezio]

We are planning to do the AMS simulation in the full-chip
verification. However it's very slow to run on sigle CPU.

Can anyone provide me the infomation about SPectre with multiple CPU?

Thanks in advance

If you're talking about spectre, then in IC5033 there is an option
(on the Simulation->Options form) multithread=on and nthreads=4
(for example) which sets the number of threads to use.

When using this, the evaluation of bsim3v3 and bsim4 model equations
are split into multiple threads (as long as there are more than 512 of these
devices in the circuit). It doesn't completely run everything in parallel, just
the model equation evaluation.
