Abstract
Disclosed are methods and systems for specifying an analytical wirelength formulation that is continuous along with its derivative. One approach performs a wirelength estimate in which a continuous formulation is employed to identify and use a bounding box to enclose circuit elements of a net, and in which an attribute of the bounding box may be completely or partially diagonal. Such formulations are used for optimizing the wirelength using numerical approaches.
