Is it possible to run xschem from a command line (with a specified configuration) in order to generate netlist out of schematic? I would like to elaborate some CI solution starting from xschem. @Stefan Schippers

Using

-n

will generate a netlist for the given schematic file. You can use

-o

also to control the location of the output netlist. Example:

Xschem -n -o .  schematic.sch

The result will be the netlist of the given schematic at the same location.

@Mohamed Monem thank you, I also found

xschem -sxq -n sg13g2_tests/dc_ptap1.sch

useful and it does what it is supposed to do perfectly.
