How does one obtain a Nyquist plot in Spectre from an stb simulation?

Go to the results browser (assuming you're using wavescan or ViVA), and click on the stb-stb results. Select the loopGain signal and either change the plot type in the results browser from Default or Rectangular to "Polar", or do Settings->Graph Type->Polar - then hit the plot icon or do right-mouse-button->Plot
