Hi,
I am designing an injection-locked VCO, which requires a PLL to work properly. so I want to put my VCO in an Ideal PLL. I use PLLMMlib and PLL macro model wizard available in virtuoso, according to "VCO spectreRF workshop". at very first step, I chose VCO bench in PLL macro model wizard to run pss & pnoise to create a noise model of my VCO to replace it in the Ideal PLL. According to the existence of periodic source in VCO, I must not to check the oscillator box in PSS analysis.
However, when I do the simulation, the PSS is ok but for PNOISE, there is an error: "error (sfe-51): name conflict: value `vco_vout' of type `scalar string' encountered. expected value is of type `scalar instance'."
According to the "VCO spectreRF workshop", there are two Idc components at output nodes with the dc value of 0 and instance name "vco_vout" and "vco_vout1", "vco_vout" is chosen as the output probe in PNOISE analysis.
First, I am not sure if that is the correct way to analysis my VCO's phase noise response.
Next, I dont know if the error is because of the injected vco and the pss setups and how to fix the error.
