I just saw it from a book, but not detailed. anyone have more?

it use a monte carlo generator to compare with input voltage, and count times of the high level ...

dose it can replace with an analog noise generator ?

btw, I just done a A/D's simulation, it employ a built-in comparator of AVR chip (AT90S2313, i have about 20 pcs),  a capacitor and a CCS. it have not too bad liner.. error rate between 0.005V~0.05V,  I will wire it and test on my breadboard.

May be I expressed the wrong meaning, sorry for my bad english. Please correct it for me if you can.

I am familiar with the concept of Monte Carlo simulation.

In short, Noise analysis and monte carlo are two different things.

Monte Carlo uses distributions to randomly change values in your circuit to see the effect of things like part tolerance.
In large numbers of runs and including worst "corner" cases, you can gain confidence that your circuit will remain working properly
despite part tolerances. It is a statistical analysis and measurement technique.

Noise analysis will replace each component with an equivalent noise model and find for you the output noise due to the noise of the particular component.
For total uncorrelated noise sources, you may vector add the individual results (RSS) for a total output noise answer.

These are very *Brief* descriptions.

I can explain this to you. I can't comprehend it for you.
