摘　　要：针对综合处理机环境试验软件单次测试效率低、试验时间过长的问题,设计了一种可持续的综合处理机环境试验软件设计方法。根据环境试验不同测试项的依赖关系分析,提出多测试子图并发测试优化方法,减少故障导致的测试中断,提升单次测试效率;针对网络测试子图的环形拓扑结构会导致单点故障造成测试中止的问题,设计了星型网络测试拓扑结构,实现单点网络故障条件下的网络测试可持续;提出了循环测试优化设计、备份主控优化设计、结构化故障现场记录设计方法进一步提升单次环境试验的测试效率和测试结果分析效率。针对某型综合处理机环境试验测试结果表明,提出的软件设计方法大大提升了环境试验的效率,缩短了环境试验总时间。Aiming at the problems of low single test efficiency and long test time of the integrated processor environmental test software,a sustainable integrated processor environmental test software design method is designed.Based on the hierarchical characteristics of test items in the integrated processor environment test,a concurrent test process based on independent test subgraphs is designed to reduce test interruptions caused by faults and improve single test efficiency.Aiming at the problem that the test is suspended due to the single point of failure caused by the ring network topology,a star network test topology is designed to realize the continuous network test under the condition of single point network failure.In addition,the optimal design of cyclic test,the optimal design of backup master control,and the design of structured fault field record are proposed to further improve the test efficiency of a single environmental test and the analysis efficiency of test results.The environmental test results of a certain type of integrated processor show that the proposed software design method can greatly improve the efficiency of the environmental test,and the total duration of the environmental test is shortened.
