Abstract
In a placing design employing standard cell system, a series of steps of merging, improving arraying in one-dimensional array and division are fundamentally alternately repeated to obtain a two-dimensional array of a plurality of cells which have relations interconnections. In the automatic cell placing method, since division is always performed after merging, placing obtained in the previous step can be corrected resulting in placing design having small dispersion in wiring density distribution.
