| Abstract(in English) | With the complexity for VLSIs, transition fault testing is required. However, VLSIs generally have more untestable transition faults than untestable stuck at faults due to the circuit structures. From the view point of structural testing, transition fault coverage might be insufficient and potential timing defects might be escaped. Therefore, design-for-testability to improve transition fault coverage is important. In this paper, we propose LOC test generation models to test control signal lines of multiplexers with n-inputs. The assignments of control signals for the LOC test generation models are realized by controller augmentation. Our experimental results for high-level benchmark circuits show that the proposed method achieved 100% fault coverage for transition faults in the data-paths. |
