Hi guys, does anybody know how to setup the GDS3D project from University of Twente (https://github.com/trilomix/GDS3D) for a proprietary PDK? Do I have to manually specify the techfile (the ones described here : https://github.com/trilomix/GDS3D/tree/master/techfiles) or do foundries provide a techfile specifying the layers as is needed by the program ? As in, will I have to go through the PDK documentation and write a techfile in the format needed by the program or is there a file PDKs generally include which I can substitute here?
