Abstract
The method of designing a semiconductor integrated circuit of the embodiment is characterized in: reading from a memory unit a fundamental property value of a cell constituting a semiconductor integrated circuit in a case in which a variation of a property value is not taken into consideration, and reading from a memory unit variation coefficients of the property value of the cell corresponding to a dimension of a transistor constituting the cell; and performing a static timing analysis on the semiconductor integrated circuit by using the read variation coefficients and fundamental property value.
