PLLs in PSpice
How do you simulate a PLL in Pspice? I can get the right parts for an XOR, a filter and an amp, but i can't find a VCO part.

The VCO is just an integrator, as far as SPICE is concerned. If you model the VCO as an oscillator, you have to run in transient mode which takes up a lot of computer resource. I write the model so it runs in AC analysis. The output is a Bode plot of the PLL response.
