[sdiy] SPICE and Processors

[George Hearn]

I’ve been doing a lot of analogue spice recently and in particular feeding
audio into the simulation and generating .wav files from probes.  The
simulations are incredibly accurate but with a major drawback.. they take
ages.  10s of audio simulation might take 5 minutes!  
       So here’s the question, would a multi-core processor speed things
up?  Is a Core 2 Quad 2.8GHz going to run simulations faster than a Core 2
Duo 3.0GHz or is it clock rate which counts?  Do SPICE simulator engines
make use of multi-cores?  I use Proteus for simulation.  Thanks, George
