To use the final operating points in a tran sim as the basis for an stb analysis, is it as simple as making sure the tran analysis is placed above the stb analysis in Explorer? Do I need to fiddle with any options in the stb options page like "prevoppoint"?
Incidentally, I'm simulating an adaptive bias crystal oscillator, hence the need for looking at the control loop once the final op point is reached rather than the startup op point.
And as a side note APS delivers a result I expect, that is, oscillating slightly below the parallel resonant frequency of the crystal, whereas SpectreX in AX or CX mode fails to oscillate. I have opened a ticket on this.
