Mode-based reconfiguration of critical software component architectures

Designing reconfigurable yet critical embedded and complex systems (i.e. systems composed of different subsystems) requires making these systems adaptable while guaranteeing that they operate with respect to predefined safety properties. When it comes to complex systems, component-based software engineering methods provide solutions to master this complexity (ldquodivide to conquerrdquo). In addition, architecture description languages provide solutions to design and analyze critical and reconfigurable embedded systems. In this paper we propose a methodology that combines the benefits of these two approaches by leaning on both AADL and Lightweigth CCM standards. This methodology is materialized through a complete design process and an associated framework, MyCCM-HI, dedicated to designing reconfigurable, critical, and complex embedded systems.
