Abstract

半導体集積回路１０にテスト入力を印加し応答の期待値と比較して組合せ回路部１７の故障を判定するテスト入力の生成方法であって、故障有無の判定が可能な論理値と未定値を含むテストパターンを決定する第１工程と、テストパターンが印加された際に形成されるクリティカルパス１９、１９ａ、１９ｂを選定する第２工程と、クリティカルパス１９、１９ａ、１９ｂのクリティカルゲートを特定する第３工程と、ゲート状態が変化するクリティカルゲートの個数を示す状態変化数が減少するように未定値を決める第４工程とを有し、状態変化数を減少することでクリティカルパス１９、１９ａ、１９ｂからの出力遅延を防止し誤テストを回避する。
