The implementation of CAN messages has been a critical aspect of the ECU development process in recent years. The traditional approach generates more inconsistencies between the specification and the software coding (implementation), probably coding errors, and variable reproducibility of the implementation, depending on the ECU platform. Therefore in order to achieve an efficient development, the use of a high abstraction level of the CAN protocol is essential. The Eltrac approach places emphasis on integrating various phases of the traditional Sw development process for the CAN Interface, hence leading to faster production of quality code and minimizing the cost associated with fixing the problems.

In the last Years, there is the awareness that the migration to Model-based approach, allowing to System engineers and the Software engineers the use of the same executable model as working paper throughout the development process from requirements capture and specification to coding and test, is the only possibility to address the real needs of the Sw Embedded development Process (continue Specification changes, unrealistic schedule, cost reduction). Besides, in today's commercial vehicle development process, the enhancement of the vehicle or the realization of new line is obtained through the introduction of Safety critical electronics Systems. The ISO 26262 aims to ensure the functional safety related electronics systems in the Road Vehicles. Other side, the ISO 12207 describes the processes that should occur during the life cycle of a software development process from its conceptualization through its retirement.
