Model-based co-engineering and NFP analysis in embedded software sub-systems developed using heterogeneous modeling domains

In Embedded Software Engineering (ESE) scenarios involving heterogeneous modeling domains, the sub-systems may be developed using more than one modeling domain. In such scenarios, the need arises for co-engineering and model-based synchronization of Non-Functional Properties (NFPs) which are spread/linked across various modeling domains, before performing an NFP analysis. This paper proposes an integrated, generic workflow for model-based co-engineering and NFP analysis of embedded software systems developed by interdisciplinary teams, using heterogeneous modeling domains. Based on this workflow, a mechanism for model-based co-engineering and reliability analysis of an embedded software system, developed using Unified Modeling Language (UML) and Matlab/Simulink is discussed. An experimental evaluation of the proposed mechanism is presented.
