Simulation(AMS simulator) stop when results are appended or reloaded in results browser.

Pooohang1995 over 3 years ago

Hi,

After using IC 6.1.7 version, simulation(tran) is usually stopped when the output waveform is appended or re-loaded while the virtuoso is using the MMSIM license.

(simulations run using ADE-L and AMS simulator)

The simulation stopping just means the irun log is stopped and the CPU is not processing the simulation.

When I use IC 6.1.5, this issue doesn't occur.

What can I do for fixing the problem?

Thanks.

PS. IC sub-version: IC6.1.7-64b.500.12

The symptoms sound the same as an issue that was fixed in IC6.1.8 ISR18 (IC6.1.8-64b.500.18) - AMS or Spectre simulations in Virtuoso stop progressing after plotting waveforms in ViVA while the simulation is running. I didn't spot any reports of this in the 4.5 year old version you're using, but maybe it was there too. I can't really see a good reason to be using IC6.1.7 (especially if you've just moved from the really ancient IC6.1.5), so I would suggest you move to a recent hotfix of IC6.1.8 instead (make sure you update to a recent XCELIUM version too for the AMS simulator, together with a recent SPECTRE release).
