Question about a runtime option for magic's

ext2spice

command. For the -B flag is the area & perimeter information referring to the parameters ad, pd, as, ps in the extracted netlist?

Xwhatever net1 net2 net3 net4 sky130_fd_pr__pfet_01v8_lvt ad=2.23792e+12p pd=1.56048e+07u as=3.741e+12p ps=2.638e+07u w=1.29e+07u l=2e+06u

I believe the option only applies to some very outdated and unused methods for tagging terminals of a device. These can cause commented output in the netlist, which possibly at one time was recognized by some tool.
