@Stefan Schippers As seen in attached screenshot I am trying to annotate

vth

gm

vgs

of M3 NFET in testbench schematic. But after annotation only

gm

value is getting annotated on M3 symbol in schematic. Please suggest what could be issue here that

vth

and

vgs

are not getting annotated.

The save lines are correct. Transistors show only Id and gm, otherwisw they will be cluttererd with too much texts. However you can add a

devices/ngspice_get_value.sym

add add these attributes:

name=r14 node=v(@m.xm3.msky130_fd_pr__nfet_01v8[vth])
descr="vth="

1. Sorry, but could not understand what is implied in this solution. Do I need to use new NFET and PFET symbols as shown above ? 2. My objective is just to check operating point condition of NFET from

.OP

analysis by checking values of

vgs vth

gm

. How can I get them printed in ngspice output if not annotated with device symbols used in exsiting schematic?

In the ngspice repl you can type

display

to print off all available values. You can

print

a device to see detailed info. You can also

print

a single value. I have not been able to get ngspice_get_value.sym to work on my system. You can put those print commands in your script though.

Thanks @Luke Harold Miles, it was really helpful.

A short video is probably better than many words. Hope it helps!

@Stefan Schippers Thanks a lot for video!! Its' working fine.
