How to set ADE assembler expressions using the same output waveform resulting from different design variables?

NewScreenName

Hi,

I have test across different corners where a waveform is defined as a DC sweep, say VS("/vout"). 

In this test there is a design variable, say "case_var" with multiple different values (e.g. 1, 2, 3).

I would like to have an output which is the sum of the 3 resulting VS("/vout") waveforms (thus VS("/vout") @case_ver=1  + VS("/vout") @case_var=2  + VS("/vout") @case_var=3) separately for all the defined corners in the test.

How can I achieve this? I tried to pass something like (leafValue(VS("/vout") "case_var" 1) + leafValue(VS("/vout") "case_var" 2) + leafValue(VS("/vout") "case_var" 3)) but apparently this is only working when computed from the calculator, if defined as an output in ADE assembler it won't work.

Also getData does not seem helpful when the path of the psf directory and the number of corners is not known a priori.

An ocean script would be also fine as a solution

Thank you

Best regards
