Hi
I downloaded a Spice model from Avago Technologies http://www.avagotech.com/pages/en/rf_microwave/transistors/fet/atf-34143/ but the spice model seems to be not usable.
The error message given is:
ERROR(ORPSIM-15108): Subcircuit BATF34143 used by X_U8.XDIE is undefined
The Spice Model provided is:

Is there anything wrong with the Spice model?
