I've got Monte-Carlo simulations working on very basic circuits, let's say an NMOS FET with its Gate/Drain shorted and an ideal current source pumping current into that node. My models support Monte-Carlo and I can see a gaussian distribution for Vgs across 200 samples (DC Analysis). As soon as I create a current mirror, adding a second transistor's gate to this node, the monte-carlo runs fail to complete.
Actually, the monte-carlo completes several runs successfully, then fails about 50 in a row, then completes several successfully again, and so on..
The Simulation Error Message for each of the failures reads:
ERROR (Spectre-20093): disk I/O error (error code is '10')
I can't find any additional information on what this error means. My machine has plenty of disk space and routinely handles lengthy transient sims or more difficult DC operating points.
I've tried this in both ADEXL and ADE Explorer, same error.
