Using SPIN to Check Simulink Stateflow Models

Semantic Translation of Simulink/Stateflow models to

Research in the field of hybrid systems has produced a number of verification tools. Formal verification of systems is performed using such tools. In practice prototyping and simulation tools such as Matlab’s Simulink and Stateflow (MSS) are prevalent. The paper formally describes a translation process that can convert a well-defined subset of MSS into a standard form of hybrid automata. This t...

Dynamic Reliability by Using Simulink and Stateflow

The safety of high criticity industrial systems relies heavily on relatively complex programmed systems. Due to the complexity of the interactions between physical processes and their control, classical methodologies such as eventrees/fault-trees or Petri nets may not represent adequately the dynamic interactions existing between the physical processes (modeled by continuous variables) and the ...

Generating Simulink and Stateflow Models from Software Specifications

Model-Based Quantitative Safety Analysis of Matlab Simulink / Stateflow Models

In this paper we report on work in progress to extend the QuantUM approach to support the quantitative property analysis of Matlab Simulink / Stateflow models. We propose a translation of Simulink / Stateflow models to CTMCs which can be analyzed using the PRISM model checker inside the QuantUM tool. We also illustrate how the information needed to perform probabilistic analysis of dependabilit...

Towards Identifying Spurious Paths in Combined Simulink/Stateflow Models

MATLAB/Simulink and its state machine design toolbox State ̄ow are widely-used industrial tools for the development of complex embedded systems. Due to the dynamic as well as heterogeneous nature of models that contain both Simulink and State ̄ow components, their analysis poses a dif®cult challenge. This paper outlines an approach to relate the semantics of both Simulink and State ̄ow and how to ...
