Variable Pnoise Stop Frequency

IC 6.1.8.090

ADE Explorer

I am running a shooting PSS analysis to determine the output frequency of an oscillator. I also run a PNOISE analysis to report a Jitter measurement based on this PSS.

However, the oscillator output frequency varies over PVT. I would like my PNOISE simulation to have a stop frequency of half the oscillation frequency over corners.

Is this possible (or even reasonable...)? (Taking the calculated oscillator frequency and passing that value to the PNOISE analysis setup.)

Many thanks,

Conor

Hi Conor,

Right now, this isn't possible. I filed an enhancement request a little while back asking for exactly this:

CCR 1869944 Provide mechanism to sweep sampled pnoise/hbnoise to half pss fundamental for autonomous circuits

It would be a good idea if you contact customer support referencing this CCR (and this post) and ask for a duplicate to be filed - that will help with prioritisation.

Regards,

Andrew.
