I haven't simulated Switch cap in a while but this basic question came up.

The feedback in SC is caps (albeit with switches). So there is no real DC feedback. Then how can you actually simulated a switch cap amplifier for stability.
 

To simulate periodically time varying circuits Cadence provides pss, pnoise, pac etc. simulations.
There is a pstab simulation that can be used to simulate stability of switched cap or chopper circuits.
Have a look in the documentation for it.
