Optimization of Power/Ground network considering area, performance and power consumption

Due to the importance of power/ground network, lots of researches have been made on it. But they only focused on the minimal area of it. By discussion on the relation among Vdd, performance and power consumption, this paper proposes an optimal algorithm using GA and SLP method where area, performance and power consumption can be simultaneously evaluated. As a result, the power/ground network is designed by adjusting the wire width to supply the proper Vdds. The convergence of the algorithm is proved. Experimental results and simulations also show that the proposed algorithm can produce a good power/ground network.
