I don't see any issue. you mean the netlist file not generated? If you mean that code is not visible, it's because code instead of code_shown is used.

Yes Arman, I am not seeing netlist generated from schematic. How to do that ? Is any thing need to be updated in xschemrc file ?

The netlist is generated in the folder that is set by netlist dir. So did you check that folder?

Xschem, by default uses vim text editor for viewing netlists. Do you have vim installed ?

I am able to simulate now but getting error as seen in this screenshot. Please help in understanding and resolving this issue.
