PLZ help with introducing a pulse with jitter in cadence

[farid82xxx]

Hi all,

I need a jittery clock signal( jittery pulse) to test a vernier delay line circuit, any one know how to produce such a jittery pulse and by jittery I mean random variation of only rising edge of a pulse ,I appreciate for any hint or paper

regards

In the past I've made these using a triangle timing wave, and superimposing
a number of sinusoidal (vsin) sources on it, and then running it through an
inverter chain. The sine sources all have different frequencies so the jitter
appears random (though it is not).

However this will make both edges jittery. Which is a realistic outcome, while
having only one edge jitter and one perfect, is not.
