Virtual platforms are a powerful support for the development and early validation of embedded SW. However, complex smart devices are built by aggregating heterogeneous components provided by different vendors, thus requiring the development of custom ad-hoc virtual platforms. Even worse, components of the underneath HW platform may belong to different design domains, that are usually expressed using a huge variety of different languages. This high degree of heterogeneity in terms of both design and specification languages must be effectively managed by the design flow so to help engineers in assembling the final system. This paper proposes a meet-in-the-middle approach to create virtual platforms of heterogeneous systems. The starting point is a set of heterogeneous models, developed by adopting the designer’s favorite language and formalism. The methodology envisions the adoption of existing automatic translation and abstraction tools to automatically integrate models of components into a single homogeneous system-level executable description. The approach is supported by an analysis of the typical design flow, that leads to the definition of design domain/abstraction level taxonomies. Such taxonomies are then used to identify what characteristics would allow efficient system-level simulation, and the corresponding transformations to be applied to the starting models to achieve a “holistic” system executable representation. The benefit of such an approach is particularly evident on any kind of highly heterogeneous systems, such as smart devices. The proposed methodology has been applied to two case studies with different degrees of heterogeneity, with the goal exemplifying its adoption on concrete scenarios and to prove its effectiveness.
