CIRCUIT ROUTING BASED ON TOTAL NEGATIVE SLACK

A method, executed by a computer, for routing a circuit includes partitioning a netlist for a circuit into a plurality of nets, determining, for each net of the plurality of nets, a corresponding net cone to provide a corresponding plurality of net cones, computing a total negative timing slack for each net cone of the corresponding plurality of net cones, assigning routing constraints for the plurality of nets according to the total negative timing slack for the corresponding plurality of net cones, and routing the netlist according to the routing constraints. Examples of routing constraints include a routing priority, a routing weight, a scenic ratio, a wire code assignment, and a layer assignment. A corresponding computer program product and computer system are also disclosed herein.
