Completely wrong.
Agilent RFDE(ADSsim) use "ads" view.
But Agilent GoldenGate does not use "ads" view.
Agilent GoldenGate use "spectre" view, so we can use standard "analogLib" which is shipped as Cadence DFII.
Actually, "ads" view is not needed even for RFDE(ADSsim) since RFDE2004.
Except for Envelope analysis, "goldenGateLib" is not required at all.
So you can use components in "analogLib".
P.S. Some components in "goldenGateLib" have same functionalities as components in "analogLib".
"goldenGateLib" exists for keeping compatibility with very old Xpedion GoldenGate and Envelope Analysis.
But "DCFEED" and "DCBLOCK" are available only in "goldenGateLib".
For LSSP, you can use any of "goldenGateLib/PSIN" or "analogLib/psin", "analogLib/port.
About LSSP of GoldenGate, see "Lab2" of "goldenGateTraining".
