the robustness of commonly applied network indices, confirm the urge for a sufficient and representative sampling of interactions, and emphasize the significance of intraspecific variation in the context of communities and networks.
-This paper presents a scalable approach to interface between a time-triggered distributed hardware-in-theloop (HIL) simulator and the system under test (SUT) via Smart Virtual Transducers (SVTs). An SVT is an element of an HIL simulator and implements two interfaces -a standardized digital interface to a time-triggered transducer network and a transducer-specific interface. The main contribution of the approach is a separation of the execution of the simulation model and the deterministic interaction via an arbitrary transducer interface. The benefit of such separation is the temporal decoupling between simulation model execution and interaction with the SUT. Furthermore, the approach leads to a reduction of complexity of the simulation setup. The application of the approach is shown by an SVT prototype that is used to simulate a temperature sensor.
Abstract. In this paper we present a distributed Hardware-in-the-Loop (HiL) simulation approach that supports the verification and validation activities in an integrated architecture as recently developed in DE-COS (Dependable Embedded COmponents and Systems), an integrated project within the Sixth Framework Programme of the European Commission. Focusing on the interconnection between the simulated environment and the Integrated System Under Test (ISUT), our approach involves the concept of a Smart Virtual Transducer (SVT) that replaces the physical transducers of the ISUT without a probe effect on the ISUT. Our approach enables a complexity reduction for setting up an HiL simulation and supports a well-designed scalable interface to an integrated architecture. Furthermore, we support non-intrusive, deterministic interaction between the environment simulation system and the ISUT in order to guarantee reproducible test-runs. We show an exemplary application of the proposed concept by tailoring the generic components of the proposed simulation approach to an automotive park assistant system.
