Electronic control units (ECUs) are today the standard solutions to manage and control highly complex control tasks in modern vehicles for applications like powertrain, security, comfort and car-multimedia. The increasing complexity of these applications generates continuously increasing requirements and demands regarding the performance and quality of these ECUs. One of the consequences is that the part of the requested embedded control software will increase at an over proportional rate. According to recent studies the relative part of software compared with the total value of a vehicle in 2010 will achieve 13% (HypoVereinsbank / Mercer Study, 2001).
