Abstract:
1. A method of routing connections between a plurality of top side conductors on a top conductor layer of an integrated circuit package with a plurality of bottom side conductors on a bottom conductor layer of the integrated circuit package, the method comprising: reading a file specifying a set of logical connections between a plurality of top side conductors and bottom side conductors; defining at least two redistribution layers within the package, wherein a first redistribution layer is provided to route a first set of top side conductors and a second redistribution layer is provided to route a second set of top side conductors; for said first set of top side conductors, connecting one or more upper vias from said top side conductors of said top conductor layer with said first redistribution layer, and connecting one or more lower vias from said bottom side conductors of said bottom conductor layer with said first redistribution layer; and routing on said first redistribution layer one or more connections between the upper vias and the lower vias for the first set of top side conductors, thereby connecting the first set of top side conductors with their respective bottom side conductors.
