When slicing criterion is extracted from the property to be verified according some rules , the sliced eha and the original one are equivalent to the property 當(dāng)按一定規(guī)則從被驗(yàn)證的性質(zhì)中提取切片準(zhǔn)則時(shí),該算法能保證切片后的eha與原模型對性質(zhì)具有相同的滿足性。
We define a set of dependence relations through analyzing the characteristics such as hierarchy , concurrent and synchronization in eha . the algorithm of slicing eha from the slicing criterion composed of states and transitions is presented 本文通過分析eha中存在的層次、并發(fā)和同步等特征定義了一組依賴關(guān)系,對于由狀態(tài)和遷移組成的切片準(zhǔn)則,提出對eha進(jìn)行切片的算法。
Program slicing is an important technique to analyze and understand programs . a program slice s is composed of a set of statements in program p which can influence the value of a variables named v at a special program point n , in which ( n , v ) is named as slicing criterion 程序分片是一種重要的程序分析理解方法,用于從源程序中抽取對程序中特定點(diǎn)上的特定變量有影響的語句和控制條件,組成新的程序(稱作分片) ,然后通過分析分片來分析源程序的行為。
