Abstract
Aspects of the invention include systems and methods for implementing a sweepline triangulation technique to optimize spanning graphs for circuit routing. A non-limiting example computer-implemented method includes receiving an unrouted net having a plurality of elements. The elements can include pins, vias, and wires. A sweepline is passed across the unrouted net until the sweepline intersects an element of the plurality of elements. In response to the sweepline intersecting the element, the sweepline is stopped and one or more nodes on the sweepline and one or more previous nodes are identified. A connectivity graph is built from the one or more nodes and the one or more previous nodes. The connectivity graph includes one or more arcs and one or more guides. A minimum spanning tree is built by removing one or more guides from the connectivity graph and the unrouted net is routed based on the minimum spanning tree.
