I was going through Substrate Coupling Analysis User Guide.
it has been recommended as :-
Note: If you want to use SCA in your RF design ﬂow you are advised to take the CadenceSpectreRF/SCA training class. The training materials contain an RF demo circuit and a Divarule deck that contains special rules for SCA and illustrates a simulation with SpectreRF.
Can I get this training material or is there any other material which can help in this regard.
The EXT streams are obsolete now. In the past there were separate
streams for QRC (EXT), QuickView (KQV) and PVS (PVS), but these have
been combined into a newer stream, the PVE stream. So the PVE versions
are all newer than the EXT stream.
If doing Substrate Analysis, you should be able to do that with QRC (from the EXT or PVE stream, but ideally from the PVE stream). First you have to do the extraction. On the QRC form, you'd have to enable "Substrate Extract" from the Setup tab, and then this will open up the Substrate tab. Having done the extraction, you can open the Extracted form, and do QRC->QRC SND Analysis (which is the equivalent of the old Assura->Substrate AC Analysis).
