question on acmatch sim in spectre

[yvk]

Hi,

I have used 'acmatch' analysis to get stddev of AC voltage magnitude.

Here I have a special case where I need to find stddev of difference in AC magnitudes like:

mag(V1) -mag(V2)

using a vcvs in the schematic makes it mag(V1-V2) and thats not what I need.

Is there any other alternative to extract magnitude only for an AC signal using ideal elements or verilogAMS. (goal is to use ACMATCH on a mag(v1)-mag(v2) )


Thanks,
yvk
