Abstract

One key point of Real-Time Embedded Systems development is to ensure that functional and non-functional properties (NFPs) are satisfied by the implementation. For early detection of errors, the verification of NFPs is realized at the design level. Then the design model is implemented on a Real-Time Operating System (RTOS). However, the design model could be not implementable on the target RTOS. In this paper, we propose to integrate between the design and the implementation phases, a feasibility tests step to verify whether the design model is implementable on the target RTOS and a mapping step to generate the appropriate RTOS-specific model. This two-steps approach is based on an explicit description of the platform used for verification and the RTOS which is the implementation platform. Moreover an additional verification step is needed to ensure the conformity of the implementation model to the design model with regard to NFPs.
