Title: monte carlo/iip2/ocean
Post by salty on Jul 15^th, 2010, 2:15pm

Simulator: spectre/ocean

I have tried running qpss monte carlo sims. I would like to look at iip2 with mismatches. However, I can't quite figure out how to access the data in ocean. It is saving all the data from run to run, but how can I access the data from a specific run and calulate the iip2?

Use "openResults()" and "selectResult()".

You have to set "savefamilyplots=yes" in montecarlo analysis statement.
If you set this, data with "iteration" as independent variable are saved.

Using "Results Browser", show me your data structures.

It looks like I can select individual runs with

selectResult( "mc1_pac-montecarlo" "1.0" )
selectResult( "mc1_pac-montecarlo" "2.0" )
etc.

Is there a way to extract which process corner it was running?

Use "openResults()".
