 note = {近年，大規模集積回路の実速度テストにおけるキャプチャ時消費電力の増大に伴い，低消費電力指向テスト生成手法が提案されている．従来手法では，自動テスト生成ツールによって生成された初期テスト集合中の消費電力閾値以下であるキャプチャセーフテストベクトルで検出されるセーフ故障の検出を保証し，キャプチャアンセーフテスト集合でのみ検出が可能なアンセーフ故障集合を消費電力制約下で可能な限り検出するように疑似ブール最適化問題ベースのテスト生成を行い，キャプチャアンセーフテストベクトル数とアンセーフ故障数を削減した．しかしながら，目標故障数の増大に比例して，問題サイズが大規模化し，テスト生成時間が増加するという問題がある．本論文ではテスト生成時間を削減するために，故障励起条件を用いた低消費電力指向テスト生成法の高速化を提案する．実験結果では，目標故障数を考慮していないテスト生成法と比較し，テスト生成時間を最大 18.4%削減することができたことを示す．, In recent years, low power oriented test generation methods have been proposed with the increase in capture power consumption in at-speed testing of large-scale integrated circuits. An initial test set generated by automatic test generation tools is classified to capture-safe test vectors which is less than or equal to power consumption threshold values and capture-unsafe test vectors which is more than the values. The conventional methods detect all safe faults detected by the capture safe test vectors and detect as many unsafe faults detected only by the capture unsafe test set as possible. A pseudo-Boolean optimization based test generation method which detects as many unsafe faults as possible under power consumption constraints was proposed, and the numbers of capture unsafe test vectors and unsafe faults were reduced. However, the problem size and the test generation time increase in proportion to the increase in the number of target faults. In this paper, to reduce the test generation time, we propose to accelerate the low power oriented test generation method using fault excitation conditions. The experimental results show that the test generation time could be reduced by 18.4% on maximum compared to the conventional method.},
