Abstract
A category classification unit determines a net of interest from nets that show information on the connection between cells defined in logical netlist information, searches the net of interest and the nets adjacent the net of interest in layout information, and classifies the net of interest and the adjacent nets into categories set while attention is paid to how potentials of the adjacent nets operate relatively to the potential of the net of interest defined in a constraint, based on the logical netlist information and logical information in a library. A parasitic element extraction unit extracts parasitic elements of extraction elements defined in the constraint for each of the categories into which the nets are classified by the category classification unit, and outputs connection information including the parasitic elements.
