how to use hb simulation in cadence?

[fatcat1205]

Hi everybody

I am learning to design a vco right now.

In ADS, "harmonic balance" simulation is used to analyze the negative resistance in the circuit. (in ADS2009/example/RFIC/MOS_VCO_prj/NegativeR_test.dsn).

I'd like to do the same thing in cadence. but I got some problems with setup.

at the first place, I can not find V_1tone in the cadence. and then how to calculate the resistor with complex expression?

in $MMSIM_HOME//tools/spectre/examples/SpectreRF_workshop/SpectreRF_AN there is an app note about how to use spectreRF HB
