摘要
A delay analyzing apparatus receives a result of timing analysis of a target circuit, and detects, from paths in the target circuit, critical paths based on the result of the timing analysis with a detecting unit. A first calculating unit calculates an average delay distribution of the paths other than the critical paths based on an average delay value of each of the critical paths. A second calculating unit calculates a probability density distribution of the critical paths, and a third calculating unit calculates a probability density distribution of all of the paths based on the average delay distribution. A fourth calculating unit calculates difference between a statistical delay value of the critical paths and a statistical delay value of all of the paths based on the probability density distribution of the critical paths and the probability density distribution of all of the paths.
