Hello all. I noticed that whenever I try to access device parameters like

@m.xm1.m0[gm]

through the use of

.print

or

.save

commands, all the

.control

directives disappear and get replaced with

blabla

. Please, what may be the cause of this? The two screenshots show the content of the

codeshown

and the content of the generated netlist. The

.control

directives is missing in the generated netlist. Second, I'm also trying to use the op annotation feature of Xschem to view the transconductance of the devices, but even after adding the

devices/ngspice_get_value.sym

and editing it, I'm not still able to view the value of the parameters. @Stefan Schippers @Tim Edwards

@Emmanuel Innocent Oh, nice, good it is now working. 👍

Hello, how did you solve the problem? I updated Xschem and I still have the same problem.

Hello @Mohamed Amr. I'm sorry for the late reply. Is the issue now resolved on your end? I just updated and then restarted Xschem, and all started working well.

Hello @Emmanuel Innocent, it's very ok. I reinstalled Xschem but I still get the "?" mark when annotating a transistor The get value works fine, but the gm and id that are next to the transistor are not showing

Oh. I think I know what the problem is. Did you save the current and gm values? You need to explicitly same those parameters to be able to annotate them. You need to do say, the

.save m.XM1.m0[gm]

in the

codeshown

object to save the transconductance of transistors M1 ( syntax for accessing the device parameters for globalfoundries). You have to do this for all the devices you want to annotate, while changing the argument of the square bracket depending on the parameter you want to annotate. E.g threshold voltage, drain current, etc
