Virtual Prototyping through Co-simulation of a Cartesian Plotter

This paper shows a model-based design trajectory for the development of real-time embedded control software using virtual prototyping. As a test case, a Cartesian plotter is designed. Functional correctness of the plotter software has been ensured by means of co-simulation using a virtual prototype before deploying it on target. Except for the interface implementation, the software that is used in the co-simulation is identical to the software that is compiled to run on the target computing platform. Virtual prototyping is especially important if the real target can damage itself if it is operated outside its safe operation zone or when prototypes are not yet available for testing. The co-simulation of the software against a virtual prototype resulted in a first-time-right deployment on the real target

Concurrent Design of Embedded Control Software

Embedded software design for mechatronic systems is becoming an increasingly time-consuming and error-prone task. In order to cope with the heterogeneity and complexity, a systematic model-driven design approach is needed, where several parts of the system can be designed concurrently. There is however a trade-off between concurrency efficiency and integration efficiency. In this paper, we present a case study on the development of the embedded control software for a real-world mechatronic system in order to evaluate how we can integrate concurrent and largely independent designed embedded system software parts in an efficient way. The case study was executed using our embedded control system design methodology which employs a concurrent systematic model-based design approach that ensures a concurrent design process, while it still allows a fast integration phase by using automatic code synthesis. The result was a predictable concurrently designed embedded software realization with a short integration time

On model-driven design of robot software using co-simulation

Abstract. In this paper we show that using co-simulation for robot software design will be more efficient than without co-simulation. We will show an example of the plotter how the co-simulation is helping with the design process. We believe that a collaborative methodology based on model-driven design will improve the chances of closing the design loop early, improving cross-discipline design dialog, and reduce errors, saving cost and time
