Using calcVal() in Monte-Carlo simulations

Yannis79

Hello,

I am trying to use calcVal for creating a spec condition from a simulated parameter and although this works perfectly fine in corner simulations, I am having some difficulties in Monte-Carlo (and I will explain).

(I have also read "Using calcVal() and its arguments with ADE Assembler" in Resources > Rapid Adoption Kits but couldn't find any relevant information that would help me address the "issue").

In the above example I am performing a MC simulation which has 2 corners of 10 runs each. I would like to get the minimum value of variable "OC_limit_thres" out of those 10 runs and pass it as my upper limit to a range argument for variable "OC_flag_thres", so the CPK can be calculated.

So the range statement should in reality be like this:

range 32m 44.34m (for corner 0)

range 32m 43.14m (for corner 1)

If I open the Detail - Transpose view in the Results tab, the calcVal("OC_limit_thres" "Currlim_TurnOn_C11") is calculated perfectly fine for each run but here I need one single value out of those 10 runs - in this case the minimum - in order for calcVal to evalute on multiple runs of 1 corner.

How can this be done please?

Thank you in advance for your time.

    Well, speaking for myself I'm not going to have time to investigate this - it would probably need me to put together an example to try this out to ensure that I've understood everything and can find a solution (hopefully). Somebody else may be able to help, but the best thing would be to contact customer support - that's precisely the kind of question that should be handled there.

    Andrew.

    I have now opened a case with customer support.

    You can clearly see that the range spec is not validated under the Yield view because there is no CPK being calculated, so something is clearly wrong there.

    Thanks!
