It induces not only more, but also prolonged backtracks and causes more severe performance degradation than expected. In this paper, we propose a reconvergence-aware testability measure to better guide the ATPG justification process. Experiment results show that the proposed method significantly decreases the ATPG runtime, especially for circuits with deep logic level, by up to 76%. © 2019 IEEE.ATPG; backtrack; reconvergence; TestabilityATPG; backtrack; Justification process; Logic levels; Performance degradation; Re convergences; Testability; Testability measures; Timing circuitsconference paper10.1109/DDECS.2019.87246602-s2.0-85067547684
