How to define port in GoldenGate momentum

Dear all,
I am designing a balun with GoldenGate momentum.
After the s-parameter created,I co-simulate the balun with other ciucuits.I found that there is a small DC current across the two balun inputs.So strange!
I am so confused about this problem.
I guess that there would be some mistakes while converting the cadence pin to momentum port.
So,I am asking for help about the port definition.
Thank you.

What type of analysis do you run, DC, SP, HB(CR), Tran(TR) ?
Most suspicious issue is your frequency range setting in Momentum.
Generally I set Start=0Hz and Stop=100GHz with AFS(Adaptive Frequency Sampling) as Simulation Frequency Plan in Agilent Momentum.
How do you set frequency range in Momentum ?
