基于ASP的CSP模型验证性质反例生成技术研究

Counterexample generation in ASP-based CSP model verification

为了解决当前通信顺序进程(CSP)模型检测不支持在验证工具的一次运行中验证多个性质的问题,建立了基于ASP的CSP并发模型验证框架。主要研究在该框架下当待验证的系统性质不满足时生成相应性质反例的技术。把ASP程序调试中的ASP程序支撑原因分析技术应用于该问题的研究,提出了相应的反例生成算法,实例表明了该算法的正确性。

This paper proposed an ASP based framework for verifying concurrent model described by CSP to solve the problem of verifying multiple properties in one run of a model checker.It mainly discussed the problem of generating counterexamples while the verified property was not satisfied in this framework.The technique of justification of ASP program,which was usually used in the debugging of ASP programs,applied to this study and proposed an algorithm for generating property counterexamples.The effectiveness of the algorithm is shown by examples.
