如今，嵌入式系统具有强大的计算能力，因此也具有高度复杂性。在嵌入式系统中执行不同应用的情况十分常见。嵌入式系统设计需要能够高效、实用地进行模拟和验证的方法和工具。本文提出通过集成Ptolemy II和高层体系结构（HLA），以分布式方式开发和评估一种嵌入式系统的嵌入式建模与模拟解决方案，以便创建一个能够高性能执行大规模模型的环境。实验结果表明，在某些情况下使用非分布式模拟是不可行的。结果显示，当一个拥有400万个参与者的模型分布在8台不同机器上时，速度提高了4倍。文中还给出了模拟过程中每个CPU核心的执行模型。
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 embedded systems in a distributed way by the integration of Ptolemy II and the High Level Architecture (HLA), in order to create an environment with high-performance execution of large-scale models. Experimental results demonstrated that the use of a non distributed simulation for some situations can be infeasible. 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. It also presented a model of execution of each CPU core during the simulation.
