@User: I finally have the netlist-to-layout function integrated into magic with the SkyWater PDK, so that now I can generate a netlist from xschem, then go directly to magic and do "File->Import SPICE" and get an initial (unfloorplanned) layout. It would be nice if there were a simple and intuitive way in xschem to export a circuit with the subcircuit wrapper but no top level; would it be possible to make it so that you can push into a symbol and then do "Netlist" and get such a netlist? Or is there another method that I don't know about?
