The control of today’s complex electronic systems can only be created by costly software functions. With the increasing number of electronic control units, the amount and complexity of functions that engineers must design, code, test, and implement increases as well.

A graphic function model that includes all system components frequently serves as the basis for gaining a common understanding of functions. Model-based function development offers further advantages. Specifications are unambiguous and free of contradictions. They can be executed on the computer (by simulation) and experienced in the train (by rapid prototyping).

Rapid prototyping allows fast and uncomplicated design testing without having to build cost-intensive prototypes in the laboratory or vehicle. New function designs can be downloaded to a prototyping experimental hardware within a short time, and tests in the vehicle can be performed immediately.

Efficient prototyping is only possible through the use of flexible and productive hardware. ASCET-RP, INTECRIO and ETAS hardware products are perfectly suited for these requirements.
