Traac Control Systems Case Study: Problem Description and a Note on Domain-based Software Speciication
The problem of specifying a radio-based railway level crossing control system is described. It is used within the DFG-supported Priority Programme \Software Speciication" as a comparison case study for a number of participating research projects and shall ooer realistic problems from the traac control systems domain. The remainder of the paper deals with the necessity to combine the beneets of ...
متن کاملIntegrating Semi - Formal and Formal Softwarespecification
| In this paper, we report on the integration of informal, semiformal and formal system speciication techniques. We present a framework for system speciication called TRADE, within which several well-known semiformal speciication techniques are placed. TRADE is based on an analysis of structured and object-oriented requirements speciication methods. In this paper, we combine TRADE with the logi...
متن کاملSpecifying Concurrent Systems Using Object-z
Although concurrency is essentially an implementation issue, it is often advantageous to specify a system in terms of its concurrent components. In this paper we examine the speciication of concurrent systems using Object-Z. Object-Z is an extension to the formal speciication language Z which supports an object-oriented speciication style. The use of Object-Z is illustrated through two case stu...
متن کاملSynthesis from Knowledge - Based Speci cations ? ( Extended
In program synthesis, we transform a speciication into a program that is guaranteed to satisfy the speciication. In synthesis of reactive systems, the environment in which the program operates may behave nondeterministically, e.g., by generating diierent sequences of inputs in diierent runs of the system. To satisfy the speciication, the program needs to act so that the speciication holds in ev...
متن کاملGenerating Test Cases for In nite System Speci
Test case generation is a means to validate the implementation of a system a posteriori with respect to some given requirements imposed on the system. Current methods for the generation of test cases often rely on the system speciication being given as a nite automaton, which does not fully cover the situation in systems with asynchronous communication , In this paper we present an algorithm fo...
