Hello. I'm using docker and wanna to run xschem with gf180mcu. I set environmental variables but, when I run xschem there is a message that Unable to open file: ,,,,,, how can I solve it? and I ignored that message and simulate gf180mucC's nfet but it didn't work.

In the xschemrc file there should be a section
###########################################################################
#### WINDOW TO OPEN ON STARTUP: XSCHEM_START_WINDOW
###########################################################################
#### Start without a design if no filename given on command line:
#### To avoid absolute paths, use a path that is relative to one of the
#### XSCHEM_LIBRARY_PATH directories. Default: empty 
set XSCHEM_START_WINDOW {sky130_tests/top.sch}
which specifies a design to open if none is specified on the command line. You can set your XSCHEM_LIBRARY_PATH variable to the path to the sample top.sch.

there was a command line. but it doesn't work. should I change the purple line?
Ah, actually I could't edit this file. is there any way to unlock read-only?
And I just open 0_top.sch and go to a test example. but there is missing symbol T.T I'm so confused

You are our first user of GF180. I‘ll look into it tomorrow, and report back.

By changing path of nfet_03v3.sym in test_nfet_03v3.sch to
/foss/pdk/gf180mcuC/libs.tech/xschem/symbols/nfet_03v3.sym
, nfet appears. I think path setting in xschem/tests/*.sch is something wrong.

@Akira Tsuchiya Sorry for the long delay getting back to this issue. There seems to be some setup issues in
open_pdks
for
gf180mcuC
which @Curtis Mayberry has debugged (thanks for this!). We have opened an issue for getting this fixed: https://github.com/RTimothyEdwards/open_pdks/issues/368 @Tim Edwards
