we are required to use hspice in class but we aren't really being taught by the teacher ( just goes around giving lab exercises ), so i've just been trying to learn it myself.
In this simple netlist, i'm trying to get the graph of Ids - Vds. But it seems that the graph i'm getting is wrong.. can someone tell me what's wrong with my code. it's supposed to give a single curve that is increasing exponentially, not multiple decreasing curves. btw, i'm using the 2008 version of hspice..
nmos
.option post probe
M1 vdd vdd 0 0 nch l=0.6u w=0.18u
Vds vdd 0 1.8
.op
.dc Vds 0 2 0.1
.probe im1(M1)
.end
