Hi Jim,
there are a lot of parameters you can simulate, however, you must discriminate between the linear model (with phase inputs/outputs) and the nonlinear model (with signal voltages). a) linear: open loop response, closed loop BW, stability margin, loop damping b) nonlinear: lock-in time/range, pull-in time/range, hold range, aquisition time, step response, PM/FM/AM demodulation capabilities resp. limits.
For example, I use VISSIM (from visual solutions) for PLL simulation of all these parameters on a block system basis. If you vary the incoming frequency during simulation it is possible to see the complete pull-in process. Regards Lutz (Germany)
