  • Methods for physical layout estimation
    Patent number: 8954905
    Abstract: In one embodiment of the invention, a physical layout wire-load algorithm is used to generate a wire-load model based on physical data including aspect ratio and wire definitions defined in a physical library. The physical layout estimator is utilized to dynamically produce the physical layout wire-load model and to calculate net length and delay for each optimization iteration.
    Type: Grant
