Abstract. We describe an approach to the model-based engineering of embedded and cyber-physical systems, based on the semantic integration of diverse discipline-specific notations and tools. Using the example of a small unmanned aerial vehicle, we explain the need for multiple notations and collaborative modelling. Learning from experience with binary co-modelling based on a bespoke operational semantics, we describe current work delivering an extended approach that enables integration of multiple models and tools in a consistent tool chain, founded on an extensible semantic framework exploiting the Unifying Theories of Programming.

“…The Crescendo tool is structured as in Figure 8, where the master co-simulation engine coordinates the DE simulator (realised in the Overture/VDM tool [22]) and the CT simulator (realised by the 20-sim solvers). Based on the contract, the co-simulation engine exchanges data between the simulators and produce logs of results.…”

“…One famous example is VDM. As introduced in [6], "Overture" is developed to be a common open-source platform integrating a range of tools for constructing and analyzing formal models of systems using VDM. Nowadays, "Overture" has been updated to be a stable and mature platform, but restricted by features of VDM, it could not support effectively on describing the architecture of whole software.…”

Abstract-SOFL formal specifications have been proved to be useful and expressive enough in describing functional requirements for software development. Based on SOFL formal specifications, many techniques have been proposed to provide us with effective solutions for software verification and validation.To support these techniques, a tool support for analysis of specifications is necessary. However, such a tool is still not available. In this paper, we present our work on a supporting tool. The tool supplies two fundamental functions: syntactic analysis of SOFL formal specifications and automatic generation of functional scenarios. By syntactic analysis, we can get syntactic information of SOFL specifications. The tool can create an xml file for storing and reusing the syntax information. Functional scenarios are well-structured predicate expressions, which could be derived from formal specifications. Many formal specificationbased techniques require the generation of functional scenarios. Our tool also supports automatic generation of functional scenarios on the basis of the syntactic information.

Abstract-We present a model-driven engineering approach that enables to take energy consumption into account during the development of embedded software. In this approach we address all the constituents of a typical modern embedded solution (mechanics, communication and computation subsystems) through the application of different modelling technologies. This makes it possible to evaluate the implications of different software and system architectures in the system's energy consumption. Additionally it facilitates the exploration of the design space without having to prototype each candidate solution. We also provide details on the application of this approach to the development of a medical grade compression stocking and the benefits this approach has brought to the project currently developing this system.
