A timing analysis method includes: calculating a delay-voltage function that indicates a relationship between a delay variation rate and voltage variation; calculating a voltage-distance function that indicates a relationship between the voltage variation due to IR drop and a distance; and calculating, by combining the delay-voltage function and the voltage-distance function, a delay-distance function that indicates a relationship between the delay variation rate due to IR drop and the distance. The timing analysis method further includes: correcting, by using the delay-distance function, an OCV coefficient that depends on the distance; and executing a timing analysis of a target circuit by using the post-correction OCV coefficient. |
