AUTOSAR in Rapid Prototyping

The AUTOSAR standard allows a high level of exchangeability and reusability and provides a way to connect software components from different suppliers. Rapid control prototyping systems enable you to quickly verify how AUTOSAR software components (SWCs) behave and interact with the real plant in different development phases. A rapid control prototyping system does not require a complex, time-consuming configuration of AUTOSAR basic software and gives you much more flexibility than a later implementation on a production ECU.

 

Newly created AUTOSAR SWCs benefit from being verified before they are implemented on a production ECU. With rapid control prototyping, behavior differences between initial specification and the production implementation can be detected easily. The differences usually result from the specification being misunderstood or are simply side effects of the production implementation. When new control algorithms are developed in Simulink^®, some parts of the control strategy might already exist as AUTOSAR SWCs. These parts can be reused and combined with the new control algorithm in a single working environment without having to be recreated. This means that a proof of concept of the overall control strategy can be carried out in an early stage.

 

dSPACE offers a broad portfolio of tools covering different aspects of a stepwise AUTOSAR development process.

SystemDesk^® covers the architectural design of AUTOSAR ECUs and networks, while the production code generator TargetLink^® can generate AUTOSAR SWCs from TargetLink models. AUTOSAR SWCs originating from these tools as well as from other sources (e.g., native AUTOSAR-compliant C code) can be embedded into the familiar Simulink environment using the RTI AUTOSAR Package. This lets you connect AUTOSAR SWCs to other Simulink blocks and make use of the comprehensive dSPACE RTI implementation software. The resulting models can be verified via PC-based simulation, and also implemented and executed on the dSPACE real-time hardware. The ability to use rapid control prototyping at different stages of the development process increases reliability and enables fast design iterations.
