PSS/Pnoise analysis for divider circuit, input is pulse waveform from vsource with noise profile

I am simulating a frequency divide by 4 circuit which is flipflop/latch based and I am running pss at divider output frequency and pnoise (simulating the sampled noise analysis, multiple pnoise enabled: sample ratio for divider_in_net =4, divider_out_net=1). The vsource noise profile I input does not match to the edge phase noise plot of the vsource net.  vsource is pulse with 30-45 ps riseTime, and edgePhaseNoise is define as lets say -98 dBc at 100kHz offset
I use the standard expression: rfEdgePhaseNoise() to check input phase noise but I see -131dBc/Hz at the vsource node at 100kHz offset.

I have read many posts and tutorials about pss/pnoise analysis as well as setting up vsource but so far none of them discussed this issue. I cannot upload any images to this post
