“…For example, animation (extensive testing) of an executable model plays a vital role in the validation of an embedded integrated circuit for cellular telephones [10]. Liu's work based on the SOFL language [11], which contains elements derived from VDM, also supports direct animation of models, in this case from systematically derived execution scenarios.…”

We present a tool-supported approach to the validation of system-level timing properties in formal models of distributed real-time embedded systems. Our aim is to provide system architects with rapid feedback on the timing characteristics of alternative designs in the often volatile early stages of the development cycle. The approach extends the Vienna Development Method (VDM++), a formal objectoriented modeling language with facilities for describing real-time applications deployed over a distributed infrastructure. A new facility is proposed for stating and checking validation conjectures (assertions concerning real-time properties) against traces derived from the execution of scenarios on VDM++ models. We define validation conjectures and outline their semantics. We describe the checking of conjectures against execution traces as a formallydefined extension of the existing VDM++ tool set, and show tools to visualise traces and validation conjecture violations. The approach and tool support are illustrated with a case study based on an in-car radio navigation system.

Software design has been well recognized as an important means to achieve high reliability, and formal specification can help enhance the quality of design. However, communications between the designer and the user can become difficult via formal specifications due to the potentially complex mathematical expressions in the specification. This difficulty may lead to the situation where the user may not be closely involved in the process of constructing the specification for quality assurance. To allow formal specification to play more effective roles in software design, we put forward a new approach to deal with this problem in this paper. The approach is characterized by integrating specification animation-based inspection into the process of constructing formal design specifications. We discuss the underlying principle of the approach by explaining how specification animation is utilized as a reading technique for inspection to validate, and then evolve, the current specification towards a satisfactory one. We describe a prototype software tool for the method, and present a case study to show how the method supported by the tool works in practice.
