PLL VCO characterization

Hi all,
Could someone tell me if it is possible to plot characteristics of a VCO and a PLL using HSPICE ?
 

Re: PLL VCO characterization

Dear AdvaRes:

If you want to simulate VCO Gain, please use
1. ".alter" to change the control voltage of VCO.
2. ".meas" to get frequency.
3. use excel to plot control voltage vs frequency.

If you have any problem, please discuss here.
