A contradiction to increased performance is that faulty software also causes 30 % of severe malfunctions in the functionality of the car. Automotive winter testing activities in northern Sweden is vital to test and try out those systems. The performance of cars has during recent years become increasingly dependent on complex electronic systems used especially for safety but also comfort, performance and informatics. improved quality, by opening up for formal methods for verification.reduced need for hardware testing, by specification verification on the executable model early in the design process, and.improved efficiency of the design process through migration and reuse of executable software components, and.reduced cost through adequate system design and dimensioning, and.shorter time to market through concurrent, co-operative distributed engineering, and.Its feasibility is demonstrated on a case study of a typical automotive application (traction control), and its potential advantages are discussed, as highlighted below: In this paper we extend previous work on Timber with a multi-paradigm design environment, aiming to bridge the gap between engineering disciplines by multi-body co-simulation of vehicle dynamics, embedded electronics, and embedded executable models. In this paper we undertake an approach to embedded software design based on executable models expressed in the high-level modelling paradigm of Timber. This calls for new design methodologies and tools that scale with the increasing amount and complexity of embedded systems in today's vehicles. A major challenge for the automotive industry is to reduce the development time while meeting quality assessments for their products.
