Abstract
A semiconductor integrated circuit is provided, which includes a first group of cells, in which a plural of I/O cells and/or power source cells for external input and/or output are arranged along a direction of the outer periphery of the semiconductor integrated circuit, and a second group of cells on an inner side of the first group of cells in which a plural of I/O cells and/or power source cells for external input and/or output are arranged along a direction of the outer periphery of the semiconductor integrated circuit. The intervals between the cells forming the second group of cells are wider than those between the cells forming the first group of cells.
