  • Effective netlength calculation
    Patent number: 6316944
    Abstract: The invention accurately determines propagation delay for a sawtooth pattern. Through measurement, the actual delays added per bend in the sawtooth pattern are determined and the values are then used in a CAD tool. The invention can add a known amount of propagation delay to a wire length by routing net wires close together without using a large amount of board space.
