“…For example, this allows selecting only a small portion of the system to be simulated in very detail (unit under test) and the rest of the system can be simulated on higher abstraction levels to increase performance. Finally, the HLA backbone provides freedom of connecting any other event based simulator which allows an adaptation of the framework to diverse use cases like system/network design space exploration [29]. The mentioned approaches are part of our current investigations.…”

Multi-Processor System-on-Chips (MPSoCs) as evolution of traditional embedded system architectures demand for a detailed exploration on architectures and system design. Simulation time and complexity are major issues, as such systems get more and more complex. This paper presents a novel simulation framework aiming the simulation of multiple MPSoC systems on different abstraction levels while using several simulation platforms concurrently in order to address aforementioned challenges. We introduce the concept of MultiX-Simulation which enables a tradeoff between performance and accuracy and allows for the flexible adaptation to various use cases. The backbone of the framework is formed by the High Level Architecture, a simulation middleware for Parallel Discrete Event Simulation. Also within this contribution different performance aspects of the framework are evaluated by using various multi-granular MPSoC system models.

Several embedded system applications are used to control physical processes. Sensing, computation and actuation are combined thus involving a set of highly heterogeneous components, i.e., digital and analog hardware, software, energy sources, and external environment. Moreover, the growing use of networks contributes to introduce a further level of heterogeneity. All these aspects should be taken into account in the design process to find highly optimized solutions; therefore a Cyber-Physical System approach is needed. In particular, simulation is a key technique in the different design stages. However, the heterogeneity of components, together with the presence of the network, forces to adopt complex and slow cosimulation techniques to carry on the simulation of the entire system.This work aims at proposing SystemC as unified framework to model and simulate Networked Cyber-Physical Systems. Concerning the modeling of continuous-time components and a specific class of discrete-time components, the different Models of Computation provided by the Analog/Mixed-Signal (AMS) extension of SystemC are used. Regarding the network, SystemC and the SystemC Network Simulation Library are used to model communications at different abstraction levels. The accuracy and speed of different simulation alternatives are compared by the application to a networked control system.

“…in [12] [14], reporting about a co-simulation environment for SystemC and ns-2. Recent work from the same authors [8] introduces a TLM-based methodology for system/network design-space exploration of networked embedded systems. Another example is given in [17] where a co-simulation framework based on SystemC and OMNET++ is described focussing on the evaluation of automotive IT architectures.…”

Novel applications in the area of embedded systems evermore rely on the ability of these systems to communicate with each other. In order to avoid design errors system/ network co-simulation is a possible technique which allows investigating interdependencies between system and network already during early development stages. In this paper we present a novel synchronization method which improves performance of cycle accurate system/network co-simulation by triggering synchronization cycles solely by events generated in the network domain without losing accuracy. The implementation is set on top of a High Level Architecture based simulation platform, providing a great amount of flexibility. Results of performance analysis show that our approach is scalable in several dimensions and can significantly speedup system/network co-simulation compared to common conservative synchronization algorithms.
