Abstract

The design process for an engine management system is presented. The functional specification of the system has been captured using C and C++ as specification languages. The validation of the specification has been carried out using functional simulation. Then an architecture for the implementation of the functional specification is selected among a set of three possible alternatives, all based on the same micro-controller; characterized by different hardware-software trade-offs. The choice is motivated by a fast performance estimation that can also be used to identify the parts of the design that could be moved across the hardware-software partition to obtain better cost or better performance. The case study has been performed in the Felix VCC framework
