Title: ic615 MonteCarlo Error
Post by wave on Sep 11^th, 2012, 10:39am

Hello Running Spectre/ADE-XL, MonteCarlo gives intermittent and incomplete results.

Some run points are Ok, and have both plots and data points (min-max variation).

Other Data points have plots (so the simulation ran fine), but the min-max results do not compute or become part of a histogram.

Also, the Results ---> "Detail" graph of a certain net is labelled "error", but when you click on it, it still has a transient waveform.

The simulation logs seems like all the MC points finish simulation (though you'd never know it from the GUI)

Cadence online has a number of FAQ's describing this situation. I've tried three envSetVal("adexl.monte" .... 'boolean t) suggestions, with no improvement.
615 is slightly better in error handling than 614.

XL seems to bury the logs and troubleshooting techniques.

Suggestions?
Thanks,
Wave
