Abstract:
1. A computer program product comprising a non-transitory computer readable storage media encoding program instructions for execution on a workstation computer, said program instructions for determining a shape of one or more metal layers of a printed wiring board (PWB), wherein said program instructions are adapted for controlling a current distribution among a plurality of connector terminals of a connector mounted on the printed wiring board that commonly connect a power plane of at least one of the metal layers to a power supply wherein the program instructions comprise program instructions for: placing a connector mounting layout for connecting terminals of the connector including the plurality of connector terminals on the printed wiring board; introducing at least two slots in said at least one metal layer and proximate said plurality of connector terminals for altering the current distribution among the connector terminals; determining a profile of said current distribution among said terminals by simulating circuit conditions expected on the connector terminals; and adjusting a length of said at least one slot to equalize said current distribution among said terminals; and wherein the program instructions for introducing introduce two slots, one disposed at a first end of a connector mounting area bearing said plurality of connector terminals and one disposed at a second end of said connector mounting area and wherein said program instructions for adjusting adjust a length of each of said two slots to attain a substantially equal current distribution among said plurality of connector terminals.
