Robustness of modular multi-layered software in the automotive domain: a wrapping-based approach
Caroline Lu, Jean-Charles Fabre, Marc‐Olivier Killijian · 2009
New automotive modular multi-layered software organization particularly favors use and interoperability of components-off-the-shelf. However, the integration of software components is error-prone, if their coordination is not rigorously controlled. The risk of failure is increased with the possibility to multiplex software components with heterogeneous levels of criticality, observability. Most of dependability mechanisms, today, address locally errors within each component or report them to further diagnosis services. Instead, we consider a global wrapping-based approach to deal with multilevel properties to be checked on the complete multilayered system at runtime. In this paper, we introduce a framework to design robust software, from analysis to implementation issues, and we illustrate the methodology on simple case study.
