13.4.3. Power/ground network synthesis

The synthesis of a P/G network involves the determination of its topology, the placement of power pads, the appropriate sizing of power lines, and the insertion of decoupling capacitances. When designing a power distribution network, it is important that both the maximum allowable current density for each wire and the maximum voltage drop at each node are within specifications. The maximum current density constraints must be satisfied to avoid the wearing out of metal wires, whereas the voltage drop criteria are required for maintaining correct functioning of the IC. Meanwhile, it is important that the wiring resource consumption of a P/G network is minimized.
