Tim,

You should be able to use the wave port.  Check out their tutorial
"Getting Started: A full-wave SPICE problem" where their model is even a 
little more complicated than yours.

How do you know that you have negative inductance since hfss outputs 
s-parameters?

If you have more problems then talk to your local apps engineer.  That's why 
the software costs so much.

Good luck,

Mike
