Simulation framework: http://www.tesis-dynaware.com/dyna4 Vehicle electronic control units (ECUs) are more and more developed and tested in virtual simulation environments. With increasing complexity and versions of these ECUs, its not only a question of the availability of accurate simulation models. Also the admistration and traceability of simulation models, measurement data, results becomes an important issue. TESIS DYNAware simulation solutions cover both: access to the necessary simulation models and process tools for collaborative engineering.
