Run plan and Monte-Carlo for a calibrated circuit

Hi Stephan,

This certainly should work - but I would have to do some detailed tests to see whether any of the special arguments are needed for calcVal (such as matchParams or ignoreParams) to make it work. I suggest you read the documentation, try it, and if you have problems, contact customer support.

Dear Stephan,

However, not Run plan in combination with MC. Is this possible too? Can we e.g. define one run plan entry as MC at room temp and Vdd=Vddnom (for doing the calibration), and a 2nd entry for MC vs T and Vdd (for verification vs environmental corners)? Is calcVal clever enough to match the MC interations? And to share the mismatch in the DUT instances?

I believe Andrew's comment is correct if I understand your question properly Stephan!

Perhaps this Troubleshooting article was one that you initiated, but there is a recent document that details how to run a calibration procedure on a Monte-carlo based netlist at one temperature, and then take the calibrated value(s) from that calibration process and pass it to the following test runwhihc may be, for example, a temperature sweep, using the same Monte-Carlo based netlist. With multiple Monte-carlo runs (and unique calibration value(s) for each), the article indicates the appropriate set of calibration values for a given Monte-Carlo netlist are correctly passed to the sweep using that Monte-Carlo netlist. The article is at the Cadence On-lne support site URL:

The Troubleshooting article indicates:

"Starting IC6.1.8/ICADVM18.1 ISR12, the ?getFirstSweepPoint argument of CalcVal is supported for a setup involving MC with sweeps."

I hope I correctly understood your question!

Hi Shawn, I managed using getFirstSweepPoint, but I still wonder about run plan and MC and calibration. For my understanding each run plan part is its own MC run, like 1st cal test, then run in calibrated condition. However, how to pass the cal data to the next run plan entry?
