Abstract (in Japanese) (See Japanese page) 
(in English) Recently, it is indispensable to test in transition fault model due to timing defects increase along with complication and high speed of VLSI. However, the transition fault coverage tends to be lower than the stuck-at fault coverage due to untestable faults caused by the circuit structure. Therefore, there is a possibility of missing a potential failure for timing defects. Therefore, it is important to design-for-testability (DFT) to improve fault coverage in the transition fault model. In this paper, we show that transition fault coverages depend on state assignment to a controller in RTL netlist. We propose a QDT set which is an evaluation index on transition fault coverage for state assignment. Experimental results show that state assignment with high evaluation index has high transition fault coverages.
