Plotting Phase Noise for Injection Locked Ring Oscillator

Hi, I am using spectre -W( subversion 15.0.1.257) virtuoso -W(subversion IC6.1.7-64b.500.10). And I am trying to plot the Phase Noise for the Injection Locked Ring Oscillator for the Schematic shown.

But when I try to do the PSS(Shooting Engine) and PNOISE Analysis, it gives an error that PSS did not converge.

This is the Setup I have done for doing the PSS analysis.

And from the options I selected gear2.

Is this setup correct for doing the PSS Analysis for Injection Locked Ring Oscillator?

I really appreciate any help you can provide.
