Embedded control system implementation and modeling issues

Electronic control unit (ECU) manufacturers face the problem that, while most development processes now include simulation, rapid prototyping, and hardware-in-loop testing (HIL), the limitations of existing methods are preventing further growth. Perhaps the most bothersome limitation is the lack of an automated implementation tool which generates production code from the ECU model used during simulation and prototyping. Next on the wish list is a prototyping environment that accurately represents the actual target-constrained production system. This paper discusses these two problems and provides options for their solution.
