Access design parameter in Monte Carlo export statement

Octavian

 

I have the following:

parameters vdd=1

mc1 montecarlo .....{

..... 

export tflip=oceanEval("cross(v(\"outn\" ?result 'tran) 0.5 1 \"falling\" nil nil  )")

 }

 

This works but I would like to access the vdd design parameter in the oceanEval expression like this:

 export tflip=oceanEval("cross(v(\"outn\" ?result 'tran) vdd/2 1 \"falling\" nil nil  )")

 

I tried the VAR(\"vdd\")/2 but spectre complains that it cannot evaluate the ocean expression. 

Any help is appreciated.

    So that would be VAR(\"vdd\") of course. You also need to ensure that you have:

       designParamVals info what=parameters where=rawfile

    within the montecarlo analysis because otherwise it won't be saving the parameter values for the VAR() function to look up.
