The testing of cyber-physical systems requires validating device functionality for a wide range of operating conditions. The environment with which the cyber-physical device interacts, such as lungs for a medical ventilator device or a busy freeway for an autonomous vehicle, may be complex and subsequently difficult to explore all possible configurations. Computer simulations that utilize device and environment behavioral models may be used as a first stage of testing, but at some point development must occur using the real device running in real-time. We present a codesign framework for aiding cyber-physical device development where real devices or prototypes are connected to real-time models that simulate the interacting environment. Such test setups are known as digital mockups and allow for testing environment scenarios that are hard to capture with commonly-used but limited physical mockups. The framework supports model hardware/software codesign to enable models of varying speed and accuracy to be implemented within an embedded processor or as a custom coprocessor circuit on an FPGA. We describe an accompanying tool that generates code templates to reduce the time required to develop digital mockup test setups. We utilize the framework to build a digital mockup test setup for a commercial ventilator, and showcase codesign capabilities by implementing environmental models as both circuits and as instructions on a processor.

“…To standardize user-designed hardware functions having different data interfaces, the PR template [8] used in PSV is adopted to connect user-designed functions to the communication component designed in the communication layer. To further raise the utilization of logic resources, different sizes of PRRs, which can be evaluated by the exiting method, such as the reconfiguration-aware floorplacer proposed by Montone et al [25], are implemented on the FPGA.…”

To facilitate the development of the dynamically partially reconfigurable system (DPRS), we propose a model-based platform-specific co-design (MPC) methodology for DPRS with hardware virtualization and preemption. For DPRS analysis and validation, a model-based verification and estimation framework is proposed to make model-driven architecture (MDA) more realistic and applicable to the DPRS design. Considering inherent characteristics of DPRS and real-time system requirements, a semi-automatic model translator converts the UML models of DPRS into timed automata models with transition urgency semantics for model checking. Furthermore, a UMLbased hardware/software co-design platform (UCoP) can support the direct interaction between the UML models and the real hardware architecture. Compared to the existing estimation methods, UCoP can provide accurate and efficient platform-specific verification and estimation. We also propose a hierarchical design that consists of a hardware virtualization mechanism for dynamically linking the device nodes, kernel modules, and on-demand reconfigurable hardware functions and a hardware preemption mechanism for further increasing the utilization of hardware resources per unit time. Further, we realize a dynamically partially reconfigurable network security system (DPRNSS) to show the applicability and practicability of the MPC methodology. The DPRNSS can not only dynamically adapt some of its hardware functions at run-time to meet different system requirements, but also * Corresponding author: Tel.: Preprint submitted to Journal of Systems Architecture August 13, 2010 determine which mechanism will be used. Our experiments also demonstrate that the hardware virtualization mechanism can save the overall system execution time up to 12.8% and the hardware preemption mechanism can reduce up to 41.3% of the time required by reconfiguration-based methods.

“…Most of them are based on the client-server model, while recently, some systems providing real-time online collaboration, based on a peer-to-peer network, have also been presented (Chen, 2001). The integration of different commercial client CAD systems into a co-design platform has been demonstrated in some cases (Huang et al, 2010). Virtual reality (VR) based systems for collaborative product modeling were also suggested in the past (Chryssolouris et al, 2009).…”

Background: The design review process is often expensive due to the need for face-to-face meetings between the involved parties. Distributed design collaboration is made possible by advances in networking techniques. A tangible Mixed Reality (MR)-based virtual design prototype was created as a distributed virtual environment (DVE) for the purpose of improving remote design review collaboration. This tangible MR system has been developed to a point that experimental evaluation is necessary in order to understand the strengths and weaknesses of various features of the system. Methods: In this paper, we evaluated the tangible MR system against a commercial 3D distributed design review system in three aspects: the investigation of how users experienced virtual models in the tangible MR system as compared with the commercial system, the measurement of the users' attitude towards the effectiveness of the tangible MR system, and the discoveries of usability issues involved in the tangible MR interface through usability studies. Results: The findings from user feedback suggest that the tangible MR system may facilitate problem-solving and the quantity of work in a given amount of time and that virtual design displayed in the mixed scene was a useful aid in the design error detection task. Conclusion: These findings are useful for the improvement of future generations of the MR system. Also the suggestions can be further generalized to become usability guidelines for the MR developers in other applications and domains.
