It absolutely true. I can confirm that in the automotive area it would be a great breakthrough, if something like above existed. Simulink lacks multi-threaded middleware for deploying the models. Considering a wide range of complex protocols which need to be supported (from CAN to TCP/IP), clearly there is an abyss between the code generated by Simulink to the code needed. More to the point, there is no chance that people drawing diagrams would be able to get this communication code right. An Ada platform with a middleware taking care of this mess would be technically unbeatable. However, there is a problem of acceptance. People want C. Even more they want C#. Lots of projects are doomed to fail before they change their minds... -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
