International audienceThis paper presents an automatic method that has been developed in order to support international standards regarding functional safety, like ISO 26262 for automotive and DO178B for aeronautics. It describes a seamless and integrated method to formalise requirements based on pattern specification automatons and generated C-observer code. Based on such C-Observers then requirements based functional tests can be generated and formal verification can be automated as the generated C-code observers are integrated into a test and verification tool environment. The advantage of such approach includes the possibility to enable requirements-based test case generation, automatic test execution and analysis and test quality measurement by automatic generation of requirements coverage and traceability reports. The described method is in-line with the software quality standards as it is for example specified in the new automotive standard for functional safety ISO 26262. The approach has already been implemented in a first instance for the Matlab/Simulink models and production code generation with TargetLink from dSPACE
