question on acmatch sim in spectre

Hi,

I use 'acmatch' analysis to get sigma of voltage in AC analysis.

Here I have a special case where I need to find it for a 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,
yvkrishna

I don't think this is possible (from a few quick experiments of an idea to workaround it). You should contact customer support - might need an enhancement to spectre.

Regards,

Andrew.
