摘要:
Systems, methods, media, and other such embodiments are described for routing track assignment in a circuit design. One embodiment involves accessing routing data for a circuit design, and a first wire of a plurality of wires in the routing data. A second wire is identified that is related to the first wire as a parent wire along a shared routing direction. A misalignment value is calculated for the first wire and the second wire, and a new routing placement is selected for the first wire based at least in part on the misalignment value. In some embodiments, all wires in various routings of a circuit design are checked for possible misalignment in order to improve slew performance via reduction of unnecessary vias.
