Abstract
A method and system for auto-routing wiring within a PCB. In some embodiment, a first broad region within a first layer and a counterpart first broad region within a second layer are defined. The counterpart regions define a first broad via location. In some embodiments, the first and second broad via locations of the first and second layers can then be subdivided into a plurality of triangular regions. The triangular regions on the first and second layers can then be compared to more accurately locate an appropriate via location.
