A method of assigning pins to corresponding connection points in the design of computer modules where connection points on one layer need to be electrically connected through the pins to a wiring layer so as to minimize the length of the wiring between the points. A best area for selecting a pin is identified for each point that needs to use a pin, and pins are preferentially assigned to the points from their respective best areas. The method introduces a consideration of the direction of the destination point into the assignment solution and allows previous assignment methods to be used which incorrectly assumed that the direction to the destination point could be ignored.
