    • A false path detection program whereby passing points of signal lines constituting false paths are directly detected, thereby shortening the processing time necessary for the false path detection and the processing time of tools utilizing false path information. A storing section stores, in a storage device, circuit information about a circuit designed by a designer. A signal value generating section generates an impossible signal value with respect to a signal line in the circuit. A signal propagation inspecting section assigns the signal value generated by the signal value generating section to an input of a gate connected to the signal line with respect to which the signal value has been generated, and examines whether signal is propagated through the other input of the gate only when accompanied by the signal value. If signal is propagated through the other input of the gate, a passing point acquiring section acquires a passing point of the other signal line connected to the other input of the gate. A false path specifying section specifies a false path by the passing point acquired by the passing point acquiring section.
