FFT to analyze an A/D converter

Hello, I've designed an A/D converter and now want to analyze it's frequency
domain performance (i.e. SNR). I don't know exactly how to do this, so if
there are any hints, that would be good!

I read something about taking an FFT of the digital output stream. Is this
even something that Cadence does? Or do you have to somehow port the
simulation results to something like Matlab.

I'm pretty lost here...

Is it a sigma-delta ?
