KVCO simulation PSS (Periodic Steady State) Analysis Any Verilog-A models are not allowed in the simulation bench, PSS does not support Verilog-A. Do .tran analysis first to estimate the VCO frequency at the fixed Vctrl as the Beat frequency. Make sure the VCO works by setting the “Initial Condition”, “tstab” should be longer than the time the VCO needs to stable. If the VCO frequency is off the beat frequency by too much over sweeping Vctrl, PSS may fail. So confine the Vctrl to a reasonable range. After finishing simulation, go to ADE Results->Direct Plot>Main Form…open the Direct Plot Form, see later
Frequency Pushing To test the VCO frequency changing with power supply voltage variations, in the same manner as before, just change the sweeping variable to “vdd”. Notice here beat frequency is defined as a variable for easy change at the ADE.
