Semiconductor integrated circuit including standard cell, standard cell layout design method, and layout design software product stored in computer-readable recording medium

摘要

According to the present invention, there is provided a semiconductor integrated circuit layout design method of laying out standard cells by using a layout apparatus including an input unit, an arithmetic unit, and a storage unit, comprising, causing the arithmetic unit to calculate an area necessary for layout of each standard cell by using data about a plurality of kinds of standard cells having different heights in a row direction, which is stored in the storage unit in advance, causing the arithmetic unit to calculate the numbers of stages of row regions having heights corresponding to the standard cells on the basis of the calculated area, and causing the arithmetic unit to lay out the standard cells in the corresponding row regions.
