How to do the phase noise analysis to a fractional frequency divider

i want to know the phase noise of my fractional frequency divider, but since the fundemental freq (the input) must be an integer multiple of beat freq, i can't set it up properly.also the reset signals of my divider seem to fail my pnoise analysis.
So i wonder if there is another way to deliver the phase noise simulation or how to make it?

Why don't you arrange the divider ratio which is closest number of actual dividing ratio being as integer multiple of fundamental frequency? It will give you an insight at least..
