| By print the DC operationg point of MOS, you can obtain Vdsat, Vth and Vds. Then compare these two parameters. 
 If Vdsat>Vds and Vgs>Vth, MOS works at saturation region;
 If Vdsat<Vds and Vgs>Vth, MOS works at linear region;
 If Vgs<Vth and Ids<0.5nA, MOS cuts off;
 If Vgs<Vth and Ids>0.5nA, MOS works at subthreshold region.
