Rubber band routing and dynamic data representation
W.W.-M. Dai, R. Kong, Jason P. Jue, Masao Sato · 2002
A novel methodology and efficient algorithms are presented for performance driven routing based on computational geometry. A dynamic data representation using constrained triangulation is the key to achieving the efficient routability testing and incremental updating of topological routing. Variable width, variable spacing, evenly distributed spacing and thermal via insertion are used to handle crosstalk, switching noise, and thermal resistance problems.>
