I can get a MOSFET_NMOS (or any other MOS) to work in the Transient simulator.
ADS version 2003C.
I have a MOSFET_NMOS biased by a 3.3 volt V_DC and a 100 ohm resistor on the Drain, using the LEVEL1_Model (default model values). The gate is being driven by a VtStep source with a 3.3 volt step. The output is being taken at the drain.
The MOSFET won't turn on.

IDS=0.5*Kp*(W/L)*(VGS-VTH)^2 for VGS>VTH
Note: no channel modulation since Lambda=0.
default values are:
Kp=2e-5
VTO=0 and if bulk and source are shorted then VTH=0
W=L=10 um
under these conditions when VGS=3.3V
IDS=108.9 uA and
VD=3.3-(108.9u)*100=3.289 V
which is the result ADS is providing.
If you are getting different results then I missed something in the circuit.
