ABSTRACT:
An gate array system characterized in including, on a semiconductor chip, an internal cell region where internal cells are arranged in lattice and a cell region for input/output circuit including an array of input/output circuit cells disposed on the circumference of the internal cell region, and characterized in that a positional relationship between an internal cell at a specific position of the internal cell region and a specific input/output cell constituting the cell region for input/output circuit or a functional block formed at a specific position of the cell region for input/output circuit is constant irrespective of the size of a semiconductor chip.
