Abstract

A new routing algorithm is presented. It is based on a multiple star net model, force-directed placement and maze searching techniques. The algorithm inherits the power of maze routing in that it is able to route complex layouts with various obstructions. The large memory requirement of the conventional maze algorithm is alleviated through successive net refinement, which constrains the maze searching to small regions. The algorithm shows advantages in routing designs with complicated layout obstructions.
