Deembedding by Cadence Spectre and ViVA

Assume we do deembedding of two port network.
However there is no option except for Cadence Spectre and Cadence post processing environment, how can we do this task ?

Sounds like screwing with a hammer. Why not use proper tools?

I haven't tried this, but it might be what you are looking for, and it's free:

Very powerful, but overwhelming for beginners, no license required when used with file-based S-params:

Due to lack of license.

Usually I use Keysight ADS for this task.

It seems fine.
However it requires many libraries in addition to LabView Run Time Engine.

It requires registration which results in contacting from local sales.

Deembedding is no more than linear algebraic manipulation of matrix.

I can convert S-Parameters to T-Parameters, vice versa by Cadence Skill Language in DFII.
Here Cadence Spectre is not needed at all.

Yes, I think that is the way to go, if you want to use no other tools. I would also avoid Spectre here.
