@User: I have this tendency to forget, but I had put the code into magic to produce the AD/AS/PD/PS values in the netlist output for devices as subcircuits a long time ago. I just needed to update the tech file to make it happen. The most recent tech file in open_pdks (opencircuitdesign.com master branch

commit a7915eafb7da936dfca574c792a384db1b060989

will take care of it. The devices in the netlists in the libraries won't get the AD/AS/PD/PS values until the libraries are rebuilt, although I could potentially stop installing the SPICE netlists from the libraries, and have magic regenerate them by extraction as part of the PDK install.
