基于UIO測試序列的錯誤診斷算法
Fault Diagnosis for UIO Test Sequence
-
摘要: 唯一輸入輸出(Unique Input Output)測試序列是協(xié)議測試中常用的一種測試序列，在一個已有的錯誤診斷算法基礎(chǔ)上，結(jié)合UIO測試序列的一些特點，該文提出了一種應用于UIO測試序列的錯誤診斷算法。該算法充分利用了UIO測試序列給出的判定消息，及測試結(jié)果中可能的錯誤轉(zhuǎn)換后的輸入/輸出消息，從而能高效完全地診斷單個錯誤。最后用實驗數(shù)據(jù)給出了該文算法和原始算法之間的比較結(jié)果。

Abstract: UIO(Unique Input Output) test sequences are widely used in communication protocol testing. In this paper, based on an existing fault diagnosis algorithm, an improved algorithm, which utilizes as much information of UIO test sequences as possible, is proposed. This paper full uses of verdict information given by UIO test sequences and the observed input/output immediately after the potential faulty transition to guarantee the efficient diagnosis of any single fault. Some experiments to compare the algorithm with the original one are conducted and the results show that the algorithm is more efficient. -
