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.
SCA (Substrate Coupling Analysis) was end-of-lifed many years ago. The last update to it was in 2002 I believe (from the Product Notes in the IC5141 installation). In IC5141 it was end-of-lifed but still present as part of the end of life process. It's no longer there in IC61.
Instead you should investigate the Substrate extraction/analysis capabilities of QRC, which is the current Cadence product for analyzing substrate issues (and this is considerably more advanced than SCA was).
