Topological Rubberband Autorouter for Printed Circuit Boards
This is an autorouter for Printed Circuit Boards using a topological algorithm with rubberband traces. The code is written in Ruby and not too difficult, the basic ideas of this router are documented in the PHD thesis of Tal Dayan.
For pictures and some basic documentation you may visit my hompage at http://ssalewski.de/Router.html.en
There you also can find a tar archive of the code including some necessary Ruby glue code for CGAL and BOOST library.
The code works not bad already, but to make it really useful some work is still needed.
