A Distributed Simulation Platform Using HLA for Complex Embedded Systems Design

Abstract

Design complex embedded systems demands method and tools that allow the simulation and verification in an efficient and practical way. This paper proposes the development and evaluation of a distributed simulation platform of heterogeneous simulators based on High Level Architecture (HLA), a middleware for distributed discrete event simulation, in order to create an environment with high-performance execution of large-scale, heterogeneous and complex embedded systems. However, integrate hybrid systems is not trivial, because there is no guarantee that two systems that perfectly work separately will work well together. Experimental results of five different scenarios are presented, which integrate five different simulations tools: Ptolemy II, SystemC, Omnet++, Veins, Stage (a Robot Operating System compatible simulator) and physical robots. The experiments show success in application of Wireless Sensor Networks (WSN), power estimation of circuit design, robotic simulation and co-simulation of real robots.
