Two paths (arrival and required paths) as a target of analysis are united into a single path, and an on-chip random variation component sigmar about a plurality of nodes of the single path is calculated. Next, an on-chip variation component chip is calculated on the basis of the on-chip random variation component sigmar and an on-chip systematic variation component sigmas. Subsequently, a delay variation Docv is calculated on the basis of a reference delay Dbase of the entire path and the on-chip variation component sigmachip.
