The ASIC for control of the digital signal is progressing in the development of the avionics of the aircraft. In addition, the proportion used the ASIC in the industries is increasing continuously. However, it occurs the difficult problems of the maintenance of ASIC fault due to the maintenance company’s bankrupt, equipment’s aging, test equipment exchange and test requirement document’s absence in the case of avionics systems. Therefor it will be expensive repair costs. To solve these problems, we proposed the method to testing the analog board with ASIC and without the TRD. In this paper, we proposed the Dynamic Pattern test method which created the TRD based on analyzed logic data extracted from ASIC and diagnosed on the ASIC circuits at the point of level of gate. We could identify the 17 pattern from tests, and figure out faults in 16 addresses. According to the experiment for target board applied with proposed methods, it is possible to diagnose fault for abnormal computerized chip, ASIC, by utilizing test unit board. We’ve also obtained the excellent performance for fault detection.
