simulating jitter

Hi gmagistra  and esabard38V2 ,

As an academic exercise I attempted to produce white-noise based jitter using a pulsed source, a phase-shifted version of the source (set earlier than ideal by some set quantity) and a "white noise time" addition to the pre-pulse using absdelay(). Essentially, the solution that esabard38V2  proposes but the noise is in "time". I also added measurable readout of the jitter using state machines. You could play around with integrating the jitter, etc. Here are the files, and a screenshot showing how the white noise lines up with the measured jitter:

Hi MStokowski, Good job.

Another example from /groups.io/g/LTspice : But the jitter acts only from the falling edge : 

Jittered Clock.asc

Hiesabard38V2 ,

Wait, that's my version. :-)

I did find the group.io version noisy_wav.asc. Very similar solution in concept, but clever use of A devices instead of B sources. You could probably modify noisy_wav to do leading and trailing edges using a prehistory duplicate of the wave, as I've done.
