Does the ADE L simulation run with multi-core? When the simulation running I just saw 1 core usage 100% and the others around 10% usage. How can I run the simulation with multi-core so that can reduce simulation time?
Thanks!
 

I use Cadence 6.1.7 spectre circuit simulator, is that what you mean? Library is TSMC180nm
