Abstract
In a circuit design method, a computer verifies an occurrence of a noise error, specifies a noise allowable value with respect to a cell at which it is determined that the noise error occurs, and determines a parameter value used in a process step. The parameter value satisfies the noise allowable value specified with respect to the cell at which the noise error occurs.
