Systems and methods for reserving IC design spacing for power net routing

Abstract:

Various embodiments are directed to a mechanism for reserving power resources to address non-uniform and complex routings on a redistribution layer of a flip-chip. Reserving power resources may be performed by rerouting RDL nets by, for example, identifying an initial RDL net route for a RDL net; defining an outer boundary relative to the initial RDL net route, wherein a perimeter of the outer boundary is defined at a defined distance away from the initial RDL net route; defining one or more blockages extending from bumps to intersect the outer boundary; subdividing the initial RDL net route into a plurality of net portions, wherein each net portion is bounded by a portion of the outer boundary and one or more of the blockages; and rerouting at least one of the plurality of net portions to be adjacent at least one blockage bounding the circuit net portion.
