Multiple simulation for a particular Monte carlo corner.

[chava]

I want to be able to test the accuracy of my trim algorithm for
various monte carlo corners. To achieve this, I need to run two
simulations for a particular monte carlo corner as follows:

generate input.scs.
run montecarlo(simulation1) for a particular corner.
extract some parameters from simulation1 that tell us the desired
trim settings for this corner.
Use these parameters from simulation1 as input design variables and
regenerate input.scs.
run montecarlo again(simulation2) for the same corner as simulation1
to verify that trims settings have corrected for process variations/
mismatches for that particular corner.

I want to do the above procedure in a loop for each of the monte carlo
corners. This procedure would be very useful to test process or
mismatch trims. Is there a way I can do this using ocean script?

Thanks,
Chaitanya.

Please contact Cadence Customer Support on this. There's some work going on to
support this in IC61X, but maybe we can also help you out with an OCEAN-based
approach in the meantime.

Andrew.
