Method and apparatus for providing feedback from a compactor to a router to facilitate layout of an integrated circuit

摘要: One embodiment of the invention provides a system that communicates feedback from compactor to router facilitate layout an integrated circuit. The operates by first receiving routing for cell in circuit at compactor. then attempts compact routing. If compaction fails, identifies infeasibility path and rips up traces on while leaving other undisturbed. adjusts parameters associated with process reroutes using adjusted parameters. this rerouting.
