Abstract
Verification is critical to the design of large and complex systems. SPIN is a well-known and extensively used verification tool. In this paper, we consider two tool chains, one existing, WSAT, and one introduced here, that support using SPIN to model check systems specified as Simulink Stateflow models. We present algorithms for doing the necessary translations and present empirical results that show the chain using tools introduced in this paper performs better than the one using the existing WSAT tool. We also show that these tools allow SPIN to be used for model checking nondeterministic Stateflow models in addition to deterministic ones.
Highlights
Verification plays an important role in the design of large scale and complex systems
The objective of the work described in this paper is to provide a tool chain that supports using the well-known tool Simple PROMELA Interpreter (SPIN) [4] to model check systems specified as Simulink Stateflow models [5]
The section Web Service Analysis Tool (WSAT) shows the results of applying the tool path employing WSAT and the section Our Tool shows the results of using our tool for direct translation to Protocol Meta Language (PROMELA)
Summary
Verification (model checking) plays an important role in the design of large scale and complex systems. System verification ascertains whether designed systems can be executed or specified. The objective of the work described in this paper is to provide a tool chain that supports using the well-known tool SPIN [4] to model check systems specified as Simulink Stateflow models [5]. XML produced by Simulink is translated via an intermediate file format to MSL using new tools described later in this paper. Another new tool, described later in this paper, translates the intermediate file found from the Simulink produced XML directly to PROMELA. We give an example of a nondeterministic model that cannot be checked in Simulink that can be checked using SPIN which shows the diversity of application of our new tools.
