Temporal rover includes all of the temporal operators as well as others designed for discussing events that occurred in the past Temporal rover包括所有時態(tài)操作符以及為討論過去發(fā)生的事件而設(shè)計的其它操作符。
They have proved to be useful for specifying concurrent systems , since they can describe the ordering of events in time without introducing time explicitly . in ctl * formulas are composed of path quantifiers and temporal operators 和基于模擬、測試和演繹推理問題的傳統(tǒng)方法相比較,有著許多的優(yōu)點,也已經(jīng)成功地實踐于檢驗復(fù)雜的時序電路設(shè)計和通訊協(xié)議。
Studying time ' s basic attributes in detail , a time model is made at first in this context . in addition , the temporal interval and time point are analyzed and their temporal relations are described with the temporal operators 文中首先通過研究時間的基本屬性,確定表達時間的模型;進而分析時態(tài)區(qū)間和時間點并描述兩者間時態(tài)關(guān)系,并引入時態(tài)算子描述這些關(guān)系。
There are two quantifiers a ( for all computation paths ) and e ( for some computation path ) in path quantifiers ; and in temporal operators , there are five basic operators x ( next time ) , f ( eventually ) , g ( always ) , u ( until ) and r ( release ) . ctl * has two types of formulas : state formulas ( which are true in a specific state ) and path formulas ( which are true along a specific path ) ; and two useful sublogics : branching - time logic ctl and linear - time logic ltl . the distinction between the two is how they 本文首先介紹了模型檢測的一些基本概念和理論,然后介紹了與其密切相關(guān)的、在檢驗中用于描述系統(tǒng)屬性的時序邏輯,及實現(xiàn)模型檢測問題的方法,在基于上述關(guān)于概念、理論的基礎(chǔ)上,研究了診斷系統(tǒng)可診斷性的檢驗方法,說明了一個給定設(shè)備的診斷條件被破壞時當(dāng)且僅當(dāng)有臨界對的出現(xiàn),并定義了設(shè)備的耦合孿生模型,說明如何用它來尋找臨界對,最后使用模型檢測框架來構(gòu)造這個問題,把耦合孿生模型化簡為模型檢測問題。
