  • Generating and using route fix guidance
    Patent number: 8527930
    Abstract: Some embodiments of the present invention provide systems for generating and using a route fix guidance for fixing design rule violations. A route fix guidance includes information that enables a router to locally modify a routing solution to fix one or more design rule violations. A route fix guidance can include a set of two or more metal avoidance areas, wherein avoiding any one of the set of two or more metal avoidance areas during routing fixes the design rule violation. Additionally, a route fix guidance can specify a set of rectangles to remove from a routing solution, and a set of rectangles to insert into or add to a routing solution. Further, the route fix guidance can include information for moving one or more vias to new locations in the routing solution. The route fix guidance can specify a sequence in which the local modifications are to be made.
