Hspice program that no works!

I wrote a code for NMOS .35u but a problem is the mosfet don't work and Idrain=0 when I put Vgs=2
& Vds=1 also source=0.

I need help.


Vds 2 0 1
Vgs 1 0 2
M1 2 1 0 0 BSIM3v3 l=.35u w=10u;
.MODEL BSIM3v3 NMOS

I think the problem is u should also give drain area, source area, drain perimeter and source perimeter
if u don't provide those then it will not work
