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 plot-ter is designed. Functional correctness of the plotter soft-ware 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 com-piled to run on the target computing platform. Virtual pro-totyping is especially important if the real target can dam-age 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. 1.

Designing cyber-physical systems (CPS) is challenging due to the tight interactions between software, network/platform, and physical components. A co-simulation method is valuable to enable early system evaluation. In this paper, a cosimulation framework that considers interacting CPS components for design of time-triggered (TT) CPS is proposed. Virtual prototyping of CPS is the core of the proposed framework. A network/platform model in SystemC forms the backbone of the virtual prototyping, which bridges control software and physical environment. The network/platform model consists of processing elements abstracted by realtime operating systems, communication systems, sensors, and actuators. The framework is also integrated with a model-based design tool to enable rapid prototyping. The framework is validated by comparing simulation results with the results from a hardware-in-the-loop automotive simulator.

In order to cope with the increasing complexity of system design, component-based software engineering advocates the reuse and adaptation of existing software components. However, many applications particularly embedded systems consist of not only software, but also hardware components. Thus, component-based design should be extended to systems with both hardware and software components. Such an extension is not without challenges though. The extended methodology has to consider hard constraints on performance as well as di erent cost factors. Also, the dissimilarities between hardware and software (such as level of abstraction, communication primitives etc.) have to be resolved. In this paper, the authors propose such an extended component-based design methodology to include hardware components as well. This methodology allows the designer to work at a very high level of abstraction, where the focus is on functionality only. Non-functional constraints are speci ed in a declarative manner, and the mapping of components to hardware or software is determined automatically based on those constraints in the so-called hardware/software partitioning step. Moreover, a tool is presented supporting the new design methodology. Beside automating the partitioning process, this tool also checks the consistency between hardware and software implementations of a component. The authors also present a case study to demonstrate the applicability of the outlined concepts. Key words: component-based design, hardware/software co-design, hardware/software partitioning

We integrate data and control flow at the system specification level, using the two specialized and well established languages Matlab and SDL. For this we provide a modeling technique, which integrates the timing concepts and allows synchronization of vector-based computation with event based state transition. The technique is supported by a library of wrappers and communication functions, which has been implemented to make cosimulation easy to use and almost transparent to the user. A methodology formulates the rules to use the modeling technique, to partition the system, and to select communication modes. A complex industrial example illustrates the modeling technique and the methodology, and shows the efficiency of the Matlab-SDL cosimulation.

Abstract—An agile methodology for mixed signal simulation is presented allowing seamless connection of simulators on as needed basis eliminating overheads of the communication backplane, sophisticated synchronization and kernel modification. The methodology uses the SystemC AMS synchronization layer which supports user defined solvers and simulators. The cosimulation is wrapped in a statically scheduled timed dataflow node. The simulated executable specification enables co-design, partitioning, refinement, virtual prototyping and architecture exploration of the design space.
