  • Automatic routing system for circuit layout
    Publication number: 20010038612
    Abstract: A method is disclosed for automatically planning the routing of circuit paths on a routing surface by defining a topology of the circuit paths according to input data for connections to be routed and respective routing constraints associated with the connections to be routed; creating the circuit paths for connections to be routed having associated routing constraints iteratively according to the defined topology of the circuit paths within each unit zone; evaluating the circuit paths for compliance with the respective routing constraints during the step of creating the circuit paths; and saving data describing the circuit paths.
