monte-carlo simulation running one seed

frogconsultant

Hi All,

I am using 6.1.5 environment and I have ran a monte-carlo simulation over 100 runs yesterday and I load back my results. Some runs have failed and I wish to see more data on these particulars seeds. I went to the monte-carlo options and choose the specific seed number and re-run only this one with monte-carlo.

As a result, I do not have the correct seed environment and so the same results.

How could I re-run a specific seed number from a monte-carlo run with all data such dc voltage, dc operating point, waveforms specified, ...?

Thanks in advance for your help,

Fabian

  • I'm not sure I'd agree that it severely limits the usefulness, since it's still fine provided that you are not making topological changes to the design, but your point is understood. It's actually spectre that is doing this because a statistical corner just runs a single point monte carlo, but that's an implementation detail - ideally we can come up with something that is a bit more general whilst still retaining the performance benefit of doing the random number generation in the simulator rather than having to impose it from outside.

    Regards,
