Today’s increased regulatory demands on emissions and hard competition drives manufacturers of heavy vehicles to try new technologies in an attempt to fulfill regulations and get ahead of competitors. This paper describes the development of a platform that is to be used as a tool to evaluate the possibilities of incorporating an FPGA in the future ECUs of Scania CV AB. Requirements for such a platform are examined and presented. These requirements are then implemented as a technology demonstrator able to sample signals from sensors and performing computations using the sampled data. The technology demonstrator is also equipped with an interface to which current ECUs can be connected.
