Did get to this part finally on my local machine: The 2 main issues were • The .spiceinit missing in the .xschem folder. To do so link the same file in the .xscheme/simulations directory as in the project folder xschem directory • adding the save all line in the ngspice code ( the samples provided by xscheme were a great reference for these, and more about the ngspice-xschem setup can be found here: ◦ https://xschem.sourceforge.io/stefan/xschem_man/video_tutorials/install_xschem_sky130_and_ngspice.mp4 ◦ https://github.com/StefanSchippers/xschem_sky130
