  • Method and apparatus for performing parallel routing using a multi-threaded routing procedure
    Publication number: 20100169858
    Abstract: A method for designing a system to be implemented on a target device includes generating bounding boxes on the target device for nets in the system where a bounding box identifies routing resources available for routing its corresponding net. The nets in the system are assigned to a plurality of threads to be routed. The threads are executed so that a plurality of the nets are routed in parallel within their corresponding bounding box.

  • Methods for designing integrated circuits
    Patent number: 7441208
    Abstract: The process of designing an integrated circuit (“IC”) to implement a generalized circuit design includes a signoff between a front-end part of the process and a back-end part of the process. This signoff preferably takes place after at least some global routing has been done for the IC implementation, but before all final detailed routing is done for that implementation.

  • Method and apparatus for performing integrated global routing and buffer insertion
    Patent number: 7412680
    Abstract: A method for designing a system on an integrated circuit includes synthesizing the system. The system is placed on the integrated circuit. Buffer insertion is performed while selecting new branch points during routing of the system.

  • Method and apparatus for providing feedback from a compactor to a router to facilitate layout of an integrated circuit
    Patent number: 6915493
    Abstract: One embodiment of the invention provides a system that communicates feedback from a compactor to a router to facilitate layout of an integrated circuit. The system operates by first receiving a routing for a cell in an integrated circuit layout at the compactor. The system then attempts to compact the routing. If compaction of the routing fails, the system identifies an infeasibility path in the routing and rips up traces on the infeasibility path while leaving other traces undisturbed. The system then adjusts parameters associated with the routing process and reroutes the cell using the adjusted parameters. The system then attempts to compact this rerouting.
