Claim One:
1. A circuit board analyzer for dividing a layout of a circuit board into meshes and performing analytical processing based on a mesh-division model obtained by such division to extract a circuit constant associated with each mesh of the mesh-division model, the analyzer comprising: a storage unit for storing mesh position information on an analyzed mesh-division model that has gone through the analytical processing and extracted circuit constants obtained through the analytical processing in relation to each other; a division-model configuration unit for dividing the layout of a new to-be-analyzed circuit board into meshes to configure a new mesh-division model; an identical-mesh determination unit for making a comparison between mesh position information on the configured new mesh-division model and mesh position information on the analyzed mesh-division model to determine identical meshes that have identical mesh position information; and a circuit-constant extraction unit for performing analytical processing based on the new mesh-division model to extract a new circuit constant associated with each mesh of the new mesh-division model and reusing, as a new circuit constant associated with the determined identical meshes, an extracted circuit constant that is related to the mesh position information on the identical meshes.
