Hi folks So we need to approach the folks from CERN who design the KiCAD tool. What I would like to ask them is, whether they could take the code base of their PCB editor and hack it a bit, so that it can place and route VLSI designs as well. As far as I know KiCAD, it's actually already possible, by constraining the angles of the wires to 90 degrees and adding a grid lock for placement of components. What is missing though, is the ability to load gds libraries and to export it into GDS/Magic/DEF. It would be cool to have KiCAD for drawing analog circuits and then generating a VLSI layout from it, where you can drag and drop your components accordingly and connect it like in a PCB.
Cheers David
