Run-time Monitoring Architecture for RealTime Systems

Presented at INForum - Simpósio de Informática (INFORUM 2015). 7 to 8, Sep, 2015. Portugal.

Verification and testing are two of the most costly and time consuming steps during thedevelopment of safety critical systems. The advent of complex and sometimes partiallyunpredictable computing architectures such as multicore commercial-of-the-shelf platforms,together with the composable development approach dopted in multiple industrial domains suchas avionics and automotive, rendered the exhaustive testing of all situations that could potentiallybe encountered by the system once deployed on the field nearly impossible. Run-time verification(RV) is a promising solution to help accelerate the development of safety critical applications whilst maintaining the high degree of reliability required by such systems. RV adds monitors inthe application, which check at runtime if the system is behaving according to predefinedspecifications. In case of deviations from the specifications during the runtime, safeguardingmeasures can be triggered in order to keep the system and its environment in a safe state, as wellas potentially attempting to recover from the fault that caused the misbehaviour. In thiscommunication, we present a novel run-time monitoring architecture suited to safety critical applications.
