Development and Evaluation of Distributed Simulation of Embedded Systems Using Ptolemy and HLA

Nowadays, embedded systems have a huge amount of computational power and consequently, high complexity. It is quite usual to find different applications being executed in embedded systems. Embedded system design demands for method and tools that allow the simulation and verification in an efficient and practical way. This paper proposes the development and evaluation of a solution for embedded modeling and simulation of heterogeneous Models of Computation (MoCs) in a distributed way by the integration of Ptolemy II and the 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 models. Experimental results demonstrate, that the use of a non distributed simulation for some situations can be infeasible, as well as the use of distributed simulation with few machines, like one, two or three computers. It was demonstrated that a speedup of factor 4 was acquired when a model with 4,000 thousands actors were distributed in 8 different machines.
