Design of Semi-physical Simulation Test Platform Based on Hierarchical Model

Abstract

Abstract: Traditional semi-physical simulation test platform has problems such as low distributed performance and inconvenient interface expansion.In view of this,this paper adopts ‘layering+distributed’ design concept and designs a semi-physical simulation test platform.It adopts the distributed architecture and decomposes tasks such as test task scheduling and incentive data generation into the test controller,then makes the platform support the simulation and extension of various bus interfaces by means of a domain protocol library.Application and real-time evaluation results show that the proposed platform has good universality and high test efficiency.Its real-time performance can reach hundred micro seconds.

摘要： 针对传统半实物仿真测试平台分布式性能低、接口扩展性差等问题,基于“分层+分布式”设计理念设计半实物仿真测试平台。采用分布式架构将测试任务调度、激励数据生成等任务分解到测试控制器上,通过领域化协议库的方式使平台支持各种总线接口仿真及扩展。应用及实时性评估结果表明,该平台通用性好,测试效率高,实时性可达到百微秒级。
