A CAD device according to the embodiments includes means that determines signal transmission time of each signal transmission circuit in an LSI circuit, means that determines an output inversion rate of a flip-flop circuit included in each signal transmission circuit when the flip-flop circuit is exposed to radiation, means that determines a signal transmission circuit that is a critical path, means that calculates a total soft error rate of the LSI circuit on the basis of the signal transmission time, the output inversion rate, and a clock period, and means that, when a predetermined soft error rate is less than the total soft error rate of the LSI circuit as a result of comparison, reducing the total soft error rate of the LSI circuit to the extent possible without changing signal transmission time of the signal transmission circuit, which is a critical path.
