.4 multi-layer topological router for generating rubberband sketches is described. The router uses hierarchical top-down partitioning to perform global routing for all nets simultaneously. It combines this with successive refinement to help correct mistakes made before more detailed local info rmation is discovered. Layer assignment is performed during the(More)
abstract Current PCB-based routing tools are rapidly running out of steam when it comes to meeting the performance and cost challenges presented by today's packaging technologies, including thin-lm multichip modules. This paper describes SURF|a new routing system designed speciically to meet these challenges. The strength of the SURF system is derived from(More)
A multi-layer, topological detailed-router is described. This is the first router ever reported that uses a rubber-band sketch (RBS) to represent the interconnect. The detailed-router is part of SURF, a routing system for multi-chip modules and VLSI that was designed to handle efficiently large multi-layer problems. The detailed-router supports various(More)
