摘要
An adaptive subgridding method for power/ground plane simulations. The method includes superimposing a grid of cells onto a circuit plane. For each cell, the method may determine a fill ratio representing the amount of area in a given cell that overlaps with the circuit plane. For each cell having a fill ratio that is less than a predetermined upper limit or a predetermined lower limit the cell may be divided into a plurality of subcells. The method may then determine the fill ratio for each of the subcells. As with the original cells, each of the subcells having a fill ratio less than the predetermined upper limit and greater than the predetermined lower limit may be further subdivided into additional subcells. The loop may repeat itself until a predetermined integer value is reached, wherein the integer value indicates the number of times a cell may be subdivided.
