Spectre: +multithread Does it work for sweeps?

by hamidrezah@[EMAIL PROTECTED] Mar 14, 2008 at 08:51 AM

Greetings all:

I am simulating (DC analysis) a simple digital circuit that has many
inputs (~20): there are 2^20 (~1000,000) DC runs using a data sweep.

DC runs are independent of each other. So +mt seems promissing to
speedup the simulation. What I observe though is that a 4 processor
machine and a single processor machine have very similar CPU times in
Spectre report.

Can Spectre +mt handle this? Is there a trick in netlisting to tell it
the DC runs are independent? Any way in general to exceute many DC
runs in parallel in a single Spectre call (provided a multiprocessor
host)?

Thanks for any hint in advance

Regards,

Hrh.
