Abstract
A method of routing an integrated circuit package includes receiving as input a placement and routing of at least a portion of an integrated circuit package design, selecting a set of at least three trace segments from the placement and routing that includes at least one inner trace segment routed between two outer trace segments, calculating an inner line function for the inner trace segment that is equally spaced from one of an adjacent line function, an adjacent outer line function, and an adjacent outer trace segment on each side of the inner line function, calculating a pair of end points for the inner line function, and generating as output a new routing that reroutes the inner trace segment collinearly with the inner line function and terminates the inner trace segment by the pair of end points.
