An I_DDQ test method is proposed in this paper, which is applicable even if supply current measurement is impaired by noise. Wavelet transformation is used for noise elimination in the test method. In this paper, it is shown by some experiments that bridging faults will be detected by using the proposed test method. Since expert knowledge on filter design is not needed in noise elimination of the I_DDQ test method, it is expected that the test method will be used in many I_DDQ tests.
