基于公平性假设的实时的系统仿真检验

Simulation-Checking of Real-Time Systems with Fairness Assumptions

Farn Wang

摘要:

研究了稠密时间系统的模拟问题。如果规范可以匹配模型在某个时间点可以进行的每个转换,则规范模拟模型。我们还采用了Emerson和Lei的方法,并在检查仿真关系时允许多个强和弱公平性假设。此外,我们允许指定为状态谓词或事件谓词的公平性假设。我们专注于一个子类的问题,最多有一个公平的假设规范。然后,我们提出了这个子类的模拟检查算法。我们提出了一个模型的模拟规范对一个共同的环境。我们提出了有效的技术,这样的模拟考虑到共同的环境。实验结果表明,这种考虑可以显著提高仿真验证的效率。我们还报告了我们的算法在检查活性与公平性假设的性能。

英文摘要:

We investigate the simulation problem in of dense-time system. A specification simulates a model if the specification can match every transition that the model can make at a time point. We also adapt the approach of Emerson and Lei and allow for multiple strong and weak fairness assumptions in checking the simulation relation. Furthermore, we allow for fairness assumptions specified as either state-predicates or event-predicates. We focus on a subclass of the problem with at most one fairness assumption for the specification. We then present a simulation-checking algorithm for this subclass. We propose simulation of a model by a specification against a common environment. We present efficient techniques for such simulations to take the common environment into consideration. Our experiment shows that such a consideration can dramatically improve the efficiency of checking simulation. We also report the performance of our algorithm in checking the liveness properties with fairness assumptions.
