PROBLEM TO BE SOLVED: To suppress characteristic variations in transistors, which are caused by data densities of gates, in a semiconductor integrated circuit. SOLUTION: An automatic layout device 10 for the semiconductor integrated circuit determines cells to be disposed so that the number of gates existing within a prescribed region around a reference gate 111 already disposed in the vicinity of the boundary between the cells is within a prescribed range, when disposing the cells adjacently in a gate direction.
