Filed: 1991-05-29
Abstract: PURPOSE:To realize reduction of chip size by making smaller a layout area during the layout period of ROM code pattern of mask ROM. CONSTITUTION:In the case of arranging generated data 21 arranged in the sequence of address as a layout, a two-dimensional data arrangement 23 is generated first with an arrangement file 22, and fiferent one-dimensional arrangements of desired two pairs of row addresses or column addresses in such data arrangement 23 are compared with each other. If data contents are identical, any one of one-dimensional arrangements is deleted. Accordingly, a new two-dimensional data arrangement 25 is generated by conducting comparison and deletion to all one-dimensional arrangements of two pairs. A layout area can be reduced depending on data content by arranging such arrangement 25.
