The ability to quickly evaluate and revise a new function is the key to efficient software design. Models can be executed on different types of targets, i.e., on the PC, on the simulation controller of a rapid prototyping system, and on the ECU. This enables the reuse of prior results and thereby rapid iterations of software designs. In this way, the influence of the implementation – e.g., in integer, floating point or intermediate forms – and of different parameterizations can be easily investigated.

The modeling of a function's algorithm goes hand in hand with a simulation of its behavior on the PC (virtual prototyping). In the next step, a refined model, which constitutes the prototype of the target implementation, can be validated by means of a real-time simulation (rapid prototyping) under real-world conditions in the vehicle or at the test-bench. As it is not affected by the resource limitations of the microcontroller target, this approach provides for quick model modifications combined with subsequent runtime scrutiny of a given function.

INTECRIO enables prototyping of automotive electronic systems based on MATLAB®/Simulink® and ASCET models, plus C code modules. It supports function development by offering an integration and experimentation platform. For verification and validation of functions, INTECRIO supports the
ES1000 modular hardware series, the compact ES910 Rapid Prototyping Module, Microsoft Windows® based PC systems, and the Universal ETK ECU Interface.

ASCET-RP supports the modular ES1000 experimental system and the Universal ETK ECU Interface for rapid prototyping as well as INTECRIO connectivity.
