Abstract
This invention provides a storage medium on which there is stored a cell library to design a semiconductor integrated circuit to satisfy low power consumption and high speed operation and a design method using the cell library. The cell library is registered with at least two kinds of cells which are different in delay and power consumption while having the same function and the same shape. To satisfy the specification of the semiconductor integrated circuit, one cell is selected from at least two kinds of cells of the cell library.
