The latest generations of automotive electronic devices are introducing more and more complex functionalities, with more demands on software and hardware performances. From the combination of functionalities like voice recognition, graphic elaboration, and mpeg decodification in the infotelematic domain, to the hard real time requirements necessary for safety related systems. This complexity is obviously reflected in the whole process of the system development till its validation. Starting form the customer requirements specifications the software life cycle passes through several phases, each one of whom can introduce indetermination in the final results. The purpose of this paper is to show how starting from the customer specifications the basic methodologies of software development have been applied to the realizations of two ATE (Automatic Testing Equipments) for the functional verification and validation of two automotive devices with specific complex constraints in the functional and real time domains, with body/comfort and HMI functionalities. With the use of the testing equipment and methodologies described above, Ixfin Magneti Marelli Electronic Systems gained many advantages in terms of reliability, time-to-market, and development costs. Our software robustness tests assure that the product in output is more reliable; the time for verification is reduced and it's not necessary to dispose of a real prototype car for the testing. Complex, repeatable, specifically aimed tests that a normal human user could not perform, with this equipment can be. This helped for example to find out anomalies and problems that were occurring only after several cycles, and that a manual testing could not point out. Moreover through the automated testing it has become easier to guarantee the functional reliability and no regression capability on previously developed software parts.
