Hi everyone, so I was trying to run the test examples that come with the GF180MCU after the installation (

test_nfet_03v3.sch

), which brought up this error to me when I was trying to run ngspice. Any thoughts on this? Thanks!

If you look at the original .sch file in the test directory, it should have an include line with a (Tcl) variable name in it---that gets substituted by xschem when it writes the netlist. If the variable is not defined, then you'll end up with an include statement that's missing a file location, which is what your screenshot is showing. The "xschemrc" file should be defining that variable, which suggests to me that you did not start xschem in a way that would pick up the xschemrc file (like copying the xschemrc file into the directory where you are running xschem).

Hi @Tim Edwards thanks for the reply. I have the

xschemrc

located in the same directory where I am running xschem. I was also following this tutorial video () to have my GF180MCU PDK set up, especially the environment variables as well as

xschemrc

file.

Ensure you have a

.spiceinit

file in the directory where the .spice file is generated (default:

~/.xschem/simulations

), with following content:

set ngbehavior=hsa
set ng_nomodcheck 
# set filetype=ascii
set num_threads=4

This is necessary to correctly understand lib model files. I see also you are using

.inc

, this is wrong, use

.lib  blablabla typical

Thanks, @Stefan Schippers for the message. I actually solved it by doing exactly what you suggested (I missed the

.spiceinit

) which is why I deleted the thread that was asking for advice. Thanks anyway!
