Help： ADS Harmonic Balance Simulation Warnings

Hi all,

I am using ADS HB simulating a VCO. It can work, but there are many warnings:

Warning detected by HPEESOFSIM during DC analysis `Osc1'
While evaluating `dcSourceLevel':
ln() changed return type during a simulation. Not supported..
Warning detected by HPEESOFSIM during HB analysis `HB1'
While evaluating `sourceLevel':
ln() changed return type during a simulation. Not supported..
Warning detected by HPEESOFSIM during spectral noise analysis `HB_NOISE'
While evaluating `time':
ln() changed return type during a simulation. Not supported..

I can not figure out why these warnings occur and I dont know how to solve it. And i am not sure if these warnings can be ignored without affacting the simulation results.

Thanks for the help.
