TTEthernet-based architecture simulation with Ptolemy II

This paper focuses on the performance evaluation of real-time embedded architectures. Recent embedded systems mostly rely on large distributed platforms composed of sensors, calculators and actuators communicating through a shared network. In such systems, each component comes with its own mechanisms to guarantee systems integrity. In order to accurately observe behaviors and evaluate architecture properties, simulation is an efficient method if it takes into account all these mechanisms. In this work, we illustrate a modelling and simulation strategy, based on the Ptolemy II framework, to study temporal phenomena of an embedded platform. We apply the methodology on an avionics case study executed on a distributed architecture communicating via a Time-Triggered Ethernet (TTEthernet) network.
