How can I obtain the setting time of a PLL using AWR (VSS)?

Hello:

I would like to find the setting time of a PLL using Virtual System Simulator (VSS)of AWR.

I know find the setting time using a real setup. You must modulate the signal reference (40 MHz) using a Phase Modulation (modulator signal and modulation characteristics (square pulses, 1 Vpp, 1 rad, frequency: 10 Hz or a bit more) ). You can view in a oscilloscope this curve (view upload image).

But I don"t know use this method in VSS.
Do you know other method in VSS?

Thank you. See you soon.
