User: anonymous Special Issues Sample Issues Volume 10 (2004) Volume 9 (2003) ... Printed Publications available in: Comment: get: Optimized Temporal Logic Compilation Andreas Krebs wsi@krebs-net.de ruf@informatik.uni-tuebingen.de Abstract: Verification and validation are the major tasks during the design of digital hardware/software systems. Often more than 70% of the development time is spent for locating and correcting errors in the design. Therefore, many techniques have been developed to support the debugging process. Recently, simulation and test methods have been accompanied by formal methods such as equivalence checking and property checking. However, their industrial applicability is currently restricted to small or medium sized designs or to a specific phase in the design process. Therefore, simulation is still the most commonly applied verification technique. In this paper, we present a method for asserting temporal properties during simulation and also during emulation of hardware prototypes. The properties under verification are efficiently translated into an intermediate language (of a virtual machine). This intermediate representation can then be interpreted during simulation. We may also produce executable checkers running in parallel to the simulation. Furthermore, we are able to translate the properties into synthesizable hardware modules which can then be used during system emulation on FPGA-based emulators or as self test components checking the functionality during the lifetime of the system.

Temporal Mosaic Decider (draft of 14/11/99) This program uses mosaics to decide the satisfiability (or otherwise) of formulas in the temporal logic with Prior's F and P over the class of all linear flows of time. Details of the idea can be found in this paper by Marx, Mikulas and Reynolds. Press the button below to run the program on your computer: it runs as a Java applet from within this page. You will need to enter the formula using the following syntax: atomic propositions must be single lower case letters Prior's temporal connectives are 'F' (sometime in the future) and 'P' (sometime in the past); use parentheses '(' and ')' to overide left to right precedence of repeated conjunctions use parentheses '(' and ')' to overide precedence of unary over binary spaces are Ok Note that the running time is roughly exponential in the length of the formula entered. Formulas of length less than 20 are decided almost immediately. Formulas of length greater than 27 may take hours. Much longer formulas may cause all sorts of memory overflow errors. Have fun.

Other papers online The Complexity of the Temporal Logic with Until over General Linear Time Mark Reynolds Abstract It is shown that the decision problem for the temporal logic with the strict until operator over general linear time is PSPACE-complete. This shows that it is no harder to reason with arbitrary linear orderings than with discrete linear time temporal logics. New techniques are used to give a PSPACE procedure for the logic.

65. The Founder Of Modern Temporal Logic The Founder of Modern temporal logic AN Prior (19141969). He revived the medieval attempt at formulating a temporal logic for natural language. http://www.kommunikation.aau.dk/prior/on_prior/founder.htm

The Founder of Modern Temporal Logic: A. N. Prior (1914-1969) Prior went to Otago University at Dunedin in 1932. He set out to study medicine, but after a short time he instead went into philosophy and psychology. In 1934 he attended Findlay's courses on ethics and logic. Through Findlay Prior became interested in the history of logic and was introduced to Prantl's textbooks. His M.A. thesis was devoted to this subject. In 1949 Prior wrote about Findlay: "I owe to his teaching, directly or indirectly, all that I know of either Logic or Ethics". Prior was brought up as a Methodist, but while he was a student he came to consider Methodistic theology too unsystematic, and he became a Presbyterian. He also became a very active member of the Student Christian Movement (SCM). In the years about 1940 he found himself in a crisis of belief. During these years he wrote the article 'Can religion be discussed?'(1942), in which he advocated an almost atheistic position. This view, however, does not seem to have lasted very long. He continued to treasure his theological library and to join the work of the SCM. Later in his life, however, he became an agnostic. In 1943 he married Mary. From 1946 to 1958 he taught philosophy at Canterbury University College in New Zealand. In 1953 he became a professor of philosophy. In 1949 his book

Stateflow Temporal Logic Events Although temporal logic does not introduce any new events into a Stateflow model, it is useful to think of the change of value of a temporal logic condition as an event. For example, suppose that you want a transition to occur from state A exactly 10 clock cycles after activation of the state. One way to achieve this would be to define an event called ALARM and to broadcast this event CLK events after state A is entered. You would then use ALARM as the event that triggers the transition out of state A An easier way to achieve the same behavior is to set a temporal logic condition on the CLK event that triggers the transition out of state A. CLK[after(10, CLK)] Note that this approach does not require creation of any new events. Nevertheless, conceptually it is useful to think of this expression as equivalent to creation of an implicit event that triggers the transition. Hence, Stateflow supports the equivalent event notation (see Temporal Logic Events after(10, CLK) Note that the event notation allows you to set additional constraints on the implicit temporal logic "event," for example, after(10, CLK)[temp == COLD]

71. Interval Temporal Logic Interval temporal logic. Interval temporal logic (ITL) is an important class of temporal logic which was initally devised by Ben Moskowski in the 1980 s. http://www.cs.kent.ac.uk/people/staff/hb5/interval.html

Interval Temporal Logic Howard Bowman and Simon Thompson Interval Temporal Logic (ITL) is an important class of temporal logic which was initally devised by Ben Moskowski in the 1980's. Standard temporal logics (see e.g. this page ) are defined over infinite state models, for example, the models for Manna and Pnueli Linear Time Temporal Logic are infinite state sequences. However, in interval temporal logic the model theory is restricted to finite state sequences, called intervals (although, supporting infinite state sequences is currently being investigated). There are a number of reasons for being interested in such logics. One reason is that interval temporal logic lends itself to execution. This is apparent from Moskowski's initial work. In addition, a number of interesting and powerful operators arise naturally from ITL. In fact, it is straightforward to derive operators very like the constructs of imperative programming (e.g. assignment, conditionals, iteration etc). This then yields the possibility that abstract specifications and concrete implementations can be realised in the same notation, with refinement mappings between. An additional aspect of interval temporal logic is that it provides a very simple real-time model in which one unit of time is past when moving from state to state. Consequently, timings can be obtained by measuring interval lengths.

Abstract Tableau Methods have been extensively investigated for standard (infinite) temporal logics and there has been some tableau work in the interval temporal logic setting. However, this work has not considered the important projection operator. This paper responds to this deficiency by defining just such a tableau algorithm which handles the projection operator.

Temporal logic In logic , the term temporal logic is used to describe any system of rules and symbolism for representing, and reasoning about, propositions qualified in terms of time. It is sometimes also used to refer to tense logic , a particular modal logic -based system of temporal logic introduced by Arthur Prior in the Temporal logic was first studied in depth by Aristotle , and his writings are filled with a crude form of first order temporal modal binary logic. Any logic which uses the existential quantifier or the universal quantifier , is said to be a first order logic . Any logic which views time as a sequence of states , is a temporal logic, and any logic which uses only two truth values, is a binary logic. Consider the statement, "I am hungry." Though its meaning is constant in time, the truth value of the statement can vary in time. Sometimes the statement is true, and sometimes the statement is false, but the statement is never true and false simultaneously. In a temporal logic, statements can have a truth value which can vary in time. Constrast this with an atemporal logic, which can only handle statements whose truth value is constant in time. The three basic temporal operators are: Always, sometimes, and never. For more information, see:

Controller Design from Temporal Logic: Undecidability Need Not Matter online Abstract: However, we claim that the impact of these findings goes much deeper than just Duration Calculus. Formal methods are intended to be mathematically rigorous design instruments, aiming at subjecting the development process to mathematical verification. Hence, the only rationale for taking idealizations in the formal representation of a design problem is that the gains in tractability of the problem may outweigh the loss of accuracy. However, if such semantic idealizations complicate rather than simplify the design problem then there is no justification for taking them. Thus, our results may be interpreted as an indication that liberating formal models of embedded control from some of the idealizations that have been imposed for smoothening the models may enhance both their accuracy and their tractability. As this implies that similar analyses of other formal models of embedded-system specification and implementation may yield similar gains, there is quite some potential for extending our results to other temporal logics or even for exploiting them in high-level hardware synthesis technologies.

76. Reification In Temporal Logics Key Words temporal logic, reification, logical formalism. The initial language on which McDermott s temporal logic is based is classical firstorder logic. http://cms1.gre.ac.uk/rae/CSabstracts/aireview.htm

Reified Temporal Logics: An Overview J. MA and B. KNIGHT University of Greenwich, London SE18 6PF, U.K. Abstract There are three main approaches to the representation of temporal information in AI literature: the so-called method of temporal arguments that simply extends functions and predicates of first-order language to include time as the additional argument; modal temporal logics which are extensions of the propositional or predicate calculus with modal temporal operators; and reified temporal logics which reify standard propositions of some initial language (e.g., the classical first-order or modal logic) as objects denoting propositional terms. The objective of this paper is to provide an overview on the temporal reified approach by looking closely at some representative existing systems featuring reified propositions, including those of Allen, McDermott, Shoham, Reichgelt, Galton, and Ma and Knight. We shall demonstrate that, although reified logics might be more complicated in expressing assertions about some given objects with respect to different times, they accord a special status to time and therefore have several distinct advantages in talking about some important issues which would be difficult (if not impossible) to express in other approaches. Key Words: temporal logic, reification, logical formalism
