Measuring tool chain interoperability in Cyber-Physical Systems

Cyber-Physical Systems are developed through complex engineering projects that include many stakeholders and a variety of tools and processes from different engineering backgrounds. Interoperability in these development tool chains is an important aspect for well-integrated systems. Furthermore, since full tool chain interoperability is neither possible nor necessarily desired, measuring interoperability in development environments is essential for setting the right priorities. This systematic literature review gives an overview of the literature about interoperability assessment methods. A survey was conducted through digital libraries and a total of 42 papers were read. Out of these papers, 24 different interoperability assessment models were identified and analyzed. A striking find of this study is that no proof of industrial adaptation of these models was found. In this paper, we analyze the reasons for this lack of validation in the context of CPS development.

PETAM: Power estimation tool for array multipliers

Increasing demand for the mobile, low energy systems has laid emphasis on the development of low power processors. Low power design has to be incorporated into fundamental computation units, such as multipliers. The optimization of the energy-delay product in such low power multipliers will enable energy efficient computation. This study proposes a power estimation tool to analyze different array multiplier architectures, which are most commonly used in such applications. Gate level library design parameters are utilized to derive energy-delay performance for any given set of input vector patterns, and multiplier size. Vector and size dependent factors are therefore clearly identified. Examples are provided from carry save array multiplier (CSAM) and ripple carry array multiplier (RCAM) to demonstrate the capabilities for the tool.

Empirical-Evolution of Frameworks Supporting Co-simulation Tool-Chain Development

Co-simulation has been proposed as a method for facilitating integrated simulation of multi-domain models of Cyber-physical Systems (CPS). To ensure that co-simulations are well-managed, concerns beyond technical mechanisms for co-simulation also need to be addressed during tool-chain development. In this paper, an evolution of two frameworks supporting co-simulation tool-chain development is first introduced. Drawing upon the empirical findings from an initial framework SPIT developed based on model-driven techniques, we develop a service-oriented framework, SPIRIT based on model-driven and tool-integration techniques. Moreover, we propose a 3D viewpoint based method to formalize concept models of co-simulation tool-chains. In order to evaluate the evolution, we use visualizations of related concept models to compare tool-chains developed based on these two frameworks.
