Abstract
Real-time scheduling is a well-studied field with mature techniques such as Rate Monotonic Analysis. In this paper, we investigate an alternative approach to solving real-time scheduling problems with model-checking. We use the modeling formalism Hybrid Automata and the model-checker HyTech for this purpose, and illustrate advantages and limitations of this approach as compared to the conventional real-time scheduling techniques. In particular, we can use model-checking for analysis of best-case response time of tasks in addition to the worst-case response time, and we can take advantage of HyTech’s parametric analysis capability to derive task parameters such as the critical scaling factor.
