I have a few questions regarding the setup of the skywater-pdk, xschem, ngspice and magic. I have followed the instructions in open_pdks (http://opencircuitdesign.com/open_pdks/install.html). There it is stated in that xschem-sky130 should be also taken care by the installation process, if the --enable-xschem-sky130 is enabled. Is that correct? In the video in the xschem page (https://xschem.sourceforge.io/stefan/xschem_man/video_tutorials/install_xschem_sky130_and_ngspice.mp4) a few additional steps are mentioned (the more important being making a copy of the basic devices library and patching it). Aren't both instructions contradicting a bit, or at least stepping into each other? Which would be the correct procedure to follow?
