Model based Testing of Automotive Infotainment Systems
With IBM Rational Rhapsody Automotive OEMs as well as Suppliers are able to specify and test Infotainment Systems and/or Sub-Systems in a model-based fashion. Once the Rhapsody model has been developed, testing is possible by means of simulation. This happens much earlier in the development lifecycle compared to a classical approach, where hardware and software need to be physically available. Errors can be detected and fixed before the specification is handed over from the OEM to the Suppliers, which lowers the risk much earlier in the development lifecycle. The Supplier is able to test the sub-system he develops against a model-based test specification which is less ambiguous compared to textual specs and leads to faster turn-around times. This results in a much better coordination of the interfaces in the development process between Automotive-OEM and Supplier. The benefit is better scalability while complexity is growing, earlier reduction of risk and shorter overall development time.
