how to speed up transient analysis?

minci

 hi,there

i have designed a large circuit and running with transient analysis,but i find that it will take a very long time, e.g. hundreds of hours, to finish the simulation. Then i read the manuals

"Virtuoso® Analog Design Environment User Guide"

"Virtuoso® Spectre® Circuit Simulator Reference"

but only to find few information about the explanation of transient setup option.

whether it is no use to change the step option? or how can i reduce the analysis time by setup some options with lower but adequate accuracy ?

Best regards

minci

  • Hi minci

    The easiest solution would be to use "turbo" or "aps" mode during spectre simulation. This would require the appropriate licenses. To enable these modes, please go to "ADE: Setup->High Performance Simulation". You will need spectre ver7.0 and above.
