| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | With shrinking feature sizes, growing clock frequencies, and decreasing power supply voltage, modern VLSIs are increasingly suffering from the impact of timing related defects. Therefore, transition fault testing is necessary. However, test generation for transition faults generally identifies many untestable faults due to the circuit structures and functions of VLSIs. When a target fault is untestable, a test that would have covered its site is missing from the test set. As a result, the test set might not detect defects around this site, even if the defects are detectable. Therefore, design-for-testability to improve transition fault coverage is very important. QDT value were proposed as testability measure of transition fault testing for state assignments of controllers. This paper proposes a method to insert additional state transitions into controllers using extended QDT value to increase the number of sensitizable paths between state registers. Experimental results for the MCNC'91 benchmark circuits show that transition fault coverage for controllers was improved by applying our proposed method. | |
