Abstract
A non-transitory, computer-readable recording medium stores therein a program causing a computer to execute calculating, using respective standard deviations of first delay distributions of delay variation independent to each element included in a path among parallel paths in a circuit, standard deviation of a first delay distribution of the path when modeled as a series circuit; correcting the standard deviation of the first delay distribution for each element, using the calculated standard deviation of the first delay distribution of the path and a standard deviation of a first delay distribution of the path obtained by a statistical delay analysis on the circuit; obtaining a correlation distribution representing a correlation between delay and leak current of the circuit by executing, using the corrected standard deviation of the first delay distribution for each element, correlation analysis between delay and leak current of the target circuit; and outputting the obtained correlation distribution.
