M1 d g 0 0 NMODEL L=2u w=10u 
Vds d 0 
Vgs g 0 DC 5  *the DC can be implied or stated explicitly
 
* The analysis 
** sweep both Vds from 0 to 5 volts in increments of .2, and Vgs from 0 to 5 volts in increments of 1
.DC Vds 0 5 0.2  Vgs 0 5 1 
** Plot the current value through the transistor 
.plot DC I(M1)
** Need this to make right data for awaves
