Hello, I would like to characterize the impact of jitter on the pulse width (td) of the out signal shown below
I am using Spectre 17.1.0.270, and the new version of Pnoise provides a new feature called edge delay. So I set it up as it triggers at rising edge of out, and measure at the falling edge of out, such as
pnoise pnoise start=10k stop=1G maxsideband=30 noisetype=sampled \
measurement=[pm0] annotate=status
pm0 jitterevent measure=delay trigger=[late GNDA] triggerthresh=0.5 \
triggernum=1 triggerdir=rise target=[early GNDA] targetthresh=0.5 \
targetnum=1 targetdir=fall
Am I using this feature in the right way? Is it intended to do stuff like this? I am expect to see very little noise contributed from buf0, but in reality , it dominates my noise budget. Any help or explanation will be highly appreciated.
