Abstract
A method, system, and computer storage device simultaneously compare the timing of conductive signal paths in a substrate and a printed circuit board to achieve a predetermined signal timing goal. Specifically, the method automatically calculates a substrate-based length of time it will take a signal to pass within each substrate conductor (within a conductor group) and automatically calculates a board-based length of time it will take a signal to pass within each of board conductors (within the conductor group). The method automatically adds the substrate-based length of time and the board-based length of time for each of the combined substrate-board conductors to produce a combined timing for each of the combined substrate-board conductors. The method automatically compares the combined timing of each the combined substrate-board conductors to determine whether the combined substrate-board conductors pass signals within a predetermined timing variance limit.
