Sequential circuit testing has been recognized as the most difficult problem in the area of fault detection. High-performance circuits with aggressive timing constraints are usually very susceptible to delay faults. We investigated the application of tests that are generated at functional level for detection of gate-level transition faults. Based on experimental results, we developed a framework of delay test generation for non-scan sequential circuits. The provided comparison with experimental results of other approaches demonstrates the effectiveness of proposed framework. Bibl. 13, tabl. 4 (in English; abstracts in English and Lithuanian).
