A CSP-Based Trajectory for Designing Formally Verified Embedded Control Software

This paper presents in a nutshell a procedure for producing formally verified concurrent software. The design paradigm provides means for translating block-diagrammed models of systems from various problem domains in a graphical notation for process-oriented architectures. Briefly presented CASE tool allows code generation both for formal analysis of the models of software and code generation in a target implementation language. For formal analysis a highquality commercial formal checker is used

gCSP: A Graphical Tool for Designing CSP systems

For broad acceptance of an engineering paradigm, a graphical notation and a supporting design tool seem necessary. This paper discusses certain issues of developing a design environment for building systems based on CSP. Some of the issues discussed depend specifically on the underlying theory of CSP, while a number of them are common for any graphical notation and supporting tools, such as provisions for complexity management and design overview

Deadlock Detection Based on Automatic Code Generation from Graphical CSP Models

The paper describes a way of using standard formal analysis tools for checking deadlock freedom in graphical models for CSP descriptions of concurrent systems. The models capture specification of a possible concurrent implementation of a system to be realized. Building the graphical models and transforming them to a textual machine-readable form is supported by a CASE tool under development called gCSP. The model transformation allows checking certain important behavioral properties of a candidate implementation before it gets refined with application specific details and deployed in exploitation conditions. A short introduction to the modeling forms and tools is given before a demonstration of the checking procedure on two examples of (embedded) control systems is presented. These systems are modeled by a special class of CSP processes, for which a graphical mechanism for revealing and healing ill-posed concurrent compositions is prototyped too
