Tools for VLSI Design - LibreSilicon flavored Live-DVD
by Hagen SANKOWSKI 02 Feb '19

Hello Ludwig, Hello List. Thanks Ludwig for your Effort to compile some tools! I came across the fact, that the Debian family of Distributions has already compiled packages for qflow, which also includes yosys and magic.. IMHO we should have a working tool flow, which allows us to work on our project and others to follow us. Ludwig, do you like to setup and maintain a (Debian/Mint clone) Live-DVD with all tools already installed tools? I would vote (at least) for - qflow - yosys - magic - klayout - electric - (lua)latex (while with easier UTF-8 usage!) all in the latest and greatest version. Plus all stuff we are developing here, like - lsc - popcorn - melmac - ... etc. Additional (in later versions) I can think about distributing nice documentations not only about the process, but also how-to, cookery books of how to make chips. A Linux Live-System is obviously the best way to let rubbernecks try out LibreSilicon without the need to struggle through a large installation process. Someone like to take the task?? Or who has great contacts to package manager for keeping the packages actual? Best regards, Hagen. P.S.: the Fedora Spin with Electronic Lab is quite old, was for Fedora 13 I guess..

KiCAD VLSI design
by David Lanzendörfer 01 Feb '19

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
