@User what's the naming scheme for the spice models? I'm seeing sky130_fd_pr_f_nfet_01v8_bM02W1p65L0p15 The first bit I get, through the voltage. I see W#p## and L#p## for the width and height. The bM02, aM02, bM04, etc. seem to be different device layouts from the svg and netlist files. Is there more information on those identifiers anywhere? Or just what's in those files?
