I am playing with the first mosfet example in Silvaco MOS1 it gives out a log file with drain current vs gate voltage by default and I am trying to get the drain current vs drain voltage IV curve and it is not working it gives me a straight vertical line. I am wondering if there is something missing in the code of that example? I have snapshots attached that describe this situation. Thank you

 

If you are referring to the example mos1ex01.in, this simulation is only for a constant Vds - 0.1V so there is no data for any other drain voltage except 100mV.
mos1ex02.in runs a simulation sweeping Vds for 3 gate voltages. I think this is what you are wanting.
 

Attention at your Id-Vd plot, the X axis is "Gate Voltage" not "Drain Voltage". :roll:

Change the X axis into "Drain Voltage" axis.
