04/13/2022, 9:06 PM@User These messages indicate xschem is loading a corrupt schematic, or the xschem version is really old. Did you install xschem cloning the repository from git and compiling the executable from source files? please do not used pre-packaged xschem versions provided with debian/ubuntu/fedora, as these are way too old.
You can avoid xschem loading a schematic at startup by commenting the line
set XSCHEM_START_WINDOW ...p

04/14/2022, 6:32 AMUsually these error messages are shown if you try to open a file that is not a schematic (.sch) or a symbol (.sym).

04/14/2022, 6:34 AMIf you believe the file you are opening that is showing warning messages is a proper xschem file and if you can send that file to me i will investigate on my side.

04/14/2022, 9:35 AMMake sense, I am not opening any file. I wanted to see the attached screen so I just typed "xschem" in my command window at the place where xschemrc is there.

04/14/2022, 9:49 AMAnd what does hsa mean i think hs is hspice,
set ngbehavior = hs or hsa
Also, why do we need to intialize the below command too
set ng_nomodcheck

04/14/2022, 10:25 PMThese are options to put into a .spiceinit file, and are ngspice specific. They are documented in the manual. ng_nomodcheck will speed up loading of sky130 models. ngbehavior=hs sets hspice compatibility mode.
