I’d like to request support for S-parameters in Qspice, if necessary limited to AC analysis.
In the past I wrote and used a S → Y → freq tables parser to get S-parameters into LTspice, but there are issues with finding the correct DC operating point (even when it is included and correct as it is in the S-parameter files, I’m using. I have not yet tested this approach with Qspice but native support would be better.
In my case the DC point is necessary since I use non linear capacitance models connected to the S-parameter ports.
The use case is professional PDN analysis.
