例句與造句

1. based on the timing constraints event model of rtl ( real time logic ), the compiling algorithms for timing constraints event transform the problem of how to detect timing constraints event to the problem of how to find negative cycle in weighted directed graph, which is named as constraints graph . by simplifying constraints graph, the efficient detecting algorithms for timing constraints event have been developed, which not only has good time complexity but also can find events that violate timing constraints as early as possible . in order to verify the event detecting methods based on dynamic rules and to check its efficiency in application, experiment schemes are designed and performed on the implemented prototype system in linux environment
   帶時間約束事件的編譯算法以rtl(realtimelogic)事件模型為基礎，將帶時間約束事件的檢測轉化為在帶權值的有向圖(此即受限圖)中尋找負圈的問題，它通過化簡受限圖得到最小有效約束集；運行時事件檢測算法在最小有效約束集上檢查事件的時間約束，不但有較好的執行效率，而且能盡早地發現違反時間約束的事件。
