Routing a Multi-Terminal Critical Net: Steiner Tree Construction in the Presence of Obstacles

  title={Routing a Multi-Terminal Critical Net: Steiner Tree Construction in the Presence of Obstacles},
  author={Joseph L. Ganley and James P. Cohoon},
This paper presents a new model for VLSI routing in the presence of obstacles, that transforms any routing instance from a geometric problem into a graph problem. It is the first model that allows computation of optimal obstacle-avoiding rectilinear Steiner trees in time corresponding to the instance size (the number of terminals and obstacle border segments) rather than the size of the routing area. For the most common multi-terminal critical nets-those with three or four terminals-we observe… CONTINUE READING
