The University of Waterloo 200 University Avenue Waterloo, Ontario The Institute of Computer Research (ICR) Presents a Colloquium on Channel Routing Under the Knock-Knee Model by Dr. Teofilo F. Gonzalez of Dept. of Computer Science, University of California, Santa Barbara ABSTRACT Channel routing problems under the knock-knee model have been approached by constructing a planar layout and then wiring it in two, three or four layers. The wiring is normally generated by partitioning the diagonal diagram corresponding to the planar layout. We discuss our new layer assignment strategy for wiring in three layers a class planar layouts. This class of planar layouts includes the planar layouts generated by the currently best three-layer two-shore channel routing algorithms. Our algorithm is faster and conceptually simpler than previous algorithms. We also discuss our new upper and lower bounds for the additional area required to wire in three layers different types of planar layouts. Wednesday, August 9, 1989 3:30 p.m. William G.
