This paper presents an efficient method for optimizing the design of power/ground (P/G) networks by using locally regular, globally irregular grids. The procedure divides the power grid chip area into rectangular subgrids or tiles. Treating the entire power grid to be composed of many tiles connected to each other enables the use of a hierarchical circuit analysis approach to identify the tiles containing the nodes having the greatest drops. Starting from an initial configuration with an equal… CONTINUE READING
