Simulation and formal verification of real time systems: A case study
نویسندگان
چکیده
This paper presents and discusses a case study that applies techniques of simulation together with techniques of formal verification. A new approach in the plant modelling for formal verification of timed systems is presented. The modelling of the plant was performed by using the object-oriented language Modelica with the library for hierarchical state machines StateGraph and the simulation results were used as input for the formal verification tasks, using the model checker UPPAAL. It is presented, in a more detailed way, the part of this work that is related to the plant simulation.

In recent years, formal methods have been used as an important tool for performance evaluation and verification of a wide range of systems. In the view points of engineers and practitioners, however, there are still some major difficulties in using formal methods. In this paper, we introduce a new formal modeling language to fill the gaps between object-oriented programming languages (OOPLs) us...

متن کاملSafety Verification of Real Time Systems Serving Periodic Devices
In real-time systems response to a request from a controlled object must be correct and timely. Any late response to a request from such a device might lead to a catastrophy. The possibility of a task overrun, i.e., missing the deadline for completing a requested task, must be checked and removed during the design of such systems. Safe design of real-time systems running periodic tasks under th...
