Abstract
Various embodiments described herein provide for track assignment of wires of a network of a circuit design by dynamic programming. In particular, various embodiments use a dynamic programming process to determine a set of breaking points for a routing wire of a global-routed and layer-assigned circuit design, and to determine track assignments for each of the sub-wires (sub-routes) formed by applying the set of selected breaking points to the routing wire. This results in a set of track-assigned sub-wires (or track-assigned sub-routes), which various embodiments can connect together to generate a connected set of track-assigned sub-wires that can be used in place of the routing wire.
