Towards a Round-Trip Support for Model-Driven Engineering of Embedded Systems
Federico Ciccozzi, Antonio Cicchetti, Mikael Sjödin · 2011
In a model-driven environment aiming at generating implementation code ensuring that extra-functional properties modeled at design level are preserved at execution time, a full round-trip engineering approach is often needed. Target code is meant to be generated from design models through appropriate model transformations, once the code has been generated, quality attributes of the embedded system are evaluated by execution monitoring/analysis tools. Eventually, in order to complete a model-driven round-trip approach, provision of back-annotation of the target code analysis results to modeling level is crucial for evaluating and consequently optimizing the design models for ensuring preservation of analyzed extra-functional aspects. In this work the problem of providing such approach in terms of process and related challenges is described together with a proposed solution. Particular emphasis is put on the description of how both traceability information and code analysis results are formalized in order to enable the desired back-annotating capabilities.
