How do you go about printing the dc parameters (gm, gds, etc) of transistors in ngspice?

for example saving gm for a 1.8 V rated lvt pfet would entail:

Copy code

save @m.xm1.msky130_fd_pr__pfet_01v8_lvt[id]
print @m.xm1.msky130_fd_pr__pfet_01v8_lvt[gm]

also check out the ngspice command

show

which prints out the model parameters for every device. to see just MOSFETs you can use

show m
