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.

Key words: embedded system, semi-physical simulation, distributed architecture, simulation bus, test task scheduling, real-time performance
