The increasing penetration of mechanical engineering by information technology enables considerable benefits. We refer to such systems as advanced mechatronic systems, which relay on the close interaction of mechanics, electric/electronics, control engineering and software engineering. Hence, the design and production of such systems is an interdisciplinary and complex task. Our ambition is a new school for the design of advanced mechatronic systems. Consequently, we need an avant-garde basic system which can be used to develop and to test future applications. The miniature robot BeBot is such a basic system. This robot constitutes the test bench for the applications, being based on modern approaches, such as self-optimization, self-organization and self-coordination as well as on the use of new manufacturing technologies. }}, author = {{Gausemeier, Jürgen and Schierbaum, Thomas and Dumitrescu, Roman and Herbrechtsmeier, Stefan and Jungmann, Alexander}}, booktitle = {{Proceedings of the 9th IEEE International Conference on Industrial Informatics (INDIN)}}, publisher = {{IEEE}}, title = {{{Miniature Robot BeBot: Mechatronic Test Platform for Self-X Properties}}}, year = {{2011}}, } @inproceedings{26702, author = {{Thuy, Andreas}}, booktitle = {{Reconfigurable Communication-centric Systems-on-Chip (ReCoSoC), 2011 6th International Workshop on }}, publisher = {{IEEE Xplore}}, title = {{{ Comparison of periodic and aperiodic task models for cyber-physical-systems}}}, year = {{2011}}, } @article{26705, abstract = {{In the area of dynamic verification of virtual prototypes, functional coverage is a valuable tool for answering the "Are we done?" question and achieving verification closure. Recent verification methodologies such as OVM and UVM contain multi-language support that provides a basic SystemC version. However, due to language shortcoming they cannot be utilized for the same amount of verification tasks in the SystemC ecosystem as in other supported hardware design and verification languages. In this presentation, we propose to boost the verification capabilities of SystemC by implementing functional coverage collection and evaluation according to the same metric as defined in the widely accepted IEEE-1800 SystemVerilog cover group feature. We implement a functional coverage library to enable coverage-driven verification of SystemC designs on multiple levels of abstraction enabling value, transition, and expression coverage. To our knowledge, the overall functionalities are not available in the IEEE-1666 SystemC standard or the SCV add-on library, nor are they complete compared to the aforementioned in any publicly available SystemC library. }}, author = {{Kuznik, Christoph and Müller, Wolfgang}}, journal = {{North American SystemC User Group Meeting (16th)}}, title = {{{Verification Closure of SystemC Designs with Functional Coverage}}}, year = {{2011}}, } @inproceedings{26707, abstract = {{Planar graph routing works provably correct if the underlying network graph is connected and planar. Typically, wireless networks modeled as 2D graphs, are not planar and planar graph routing applied on such unprocessed network graphs may fail. Planarizing a given connected graph by removing intersecting links might be impossible if the outcome still needs to be a connected subgraph. It becomes even more difficult with distributed planarization techniques, where each node is allowed to use only the information about its local neighborhood. Furthermore, it is getting complicated if the nodes' assigned positions do not reflect the exact physical location. With or without exact location information, the outcome might be disconnected, nonplanar, or both of it. With all these unsolvable problems, the question arises how to apply planar graph routing in a realistic network setting? Fortunately, wireless network graphs bear one property which distinguishes them from arbitrary graphs: due to limited communication range, network links cannot become arbitrarily long. In this work we exploit this locality property to build a new localized planarization algorithm, which is location fault tolerant and which produces planar connected graphs in most cases in realistic wireless models. We evaluate our algorithm using the Log Normal Shadowing model and show that our algorithm always produces planar connected graphs in all simulations even when large location errors are present. }}, author = {{Mathews, Emi and Frey, Hannes}}, booktitle = {{IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks (WoWMoM)}}, pages = {{1--9}}, publisher = {{ IEEE Computer Society}}, title = {{{A Localized Planarization Algorithm for Realistic Wireless Networks}}}, year = {{2011}}, } @inproceedings{26710, author = {{Becker, Markus and Zabel, Henning and Müller, Wolfgang and Elfeky, Ahmed and DiPasquale, Anthony}}, booktitle = {{8.

For this, modular interfaces are a novel object-oriented synthesizable technique to overcome the conflict between a higher degree of abstraction and necessary details for further synthesis. In this paper, we present our approach to use SysML as an adequate modeling language for modular interfaces and C/C++/SystemC-based HLS. We extended SysML with annotations for synthesizable SystemC and high-level synthesis constraints and implemented a code generation scheme to achieve design flow automation.
