This was also very helpful: raw file syntax: https://spicelib.readthedocs.io/en/latest/varia/raw_file.html

Thanks so much!!

Thanks for the info. I understand the broad strokes of raw files, but I couldn't find an example with the type of analysis specified I was trying to avoid compiling and installing ngspice, but I guess I can't escape it.

I'm wondering if example *.raw files exist on the internet or someone has one or more very basic ones they could share. I really just need to know the format and syntax of these files. I'm especially interested in any *.raw file that is usable in xschem for backannotating the OP voltages, currents (?), operating point info, etc. I have a non-ngspice simulator, and I need to figure out how to take its results and backannotate into xschem. thanks!

Got it working. Thanks for all your help.

I just tried to compile and run the version of xschem with your commit. I can see your new code inside of src/token.c Do I need to change any options or modes for this to work? Unfortunately I don't see any difference in my netlist. The instances still look like this: XM1 net1 net3 VDD VDD sky130_fd_pr__pfet_01v8_lvt L=0.35 W=1 nf=1 ad='int((nf+1) /2) * W/nf * 0.29' as='int((nf+2)/2) * W/nf * 0.29' + pd='2*int((nf+1)/2) * (W/nf + 0.29)' ps='2*int((nf+2)/2) * (W/nf + 0.29)' nrd= '0.29 / W' nrs='0.29...

Hi Stefan, Wow this is amazing! Thanks so much for this addition to the code! If it's buildable right now I'll try it out. thanks! Matt

Thanks for all the investigation and explanation. I've had the benefit in the past of having other people set up my CAD tools, so I must admit some ignorance with all the different variants of SPICE and what is possible/impossible. :) For a while I was just wondering why the models don't just use these equations to find ad,as,..etc, but I realize now that you want to be able to set these if you want, and otherwise settle on reasonable defaults (these equations). For the helper functions, is there...
