摘要
随着装备系统复杂度、集成度的不断增加,系统集成故障和单元间互测因素越来越凸显,给系统级测试性分配和设计带来了新问题,主要表现在:传统方法未考虑集成故障和单元互测导致测试性指标分配不合理,系统级测试性设计缺乏系统级测试选择方法等。针对系统集成后产生的集成故障和单元间互测等情形进行了理论分析,提出了考虑集成故障与单元互测的测试性指标分配、面向集成故障的系统级测试选择方法,为系统级测试性设计提供了一套解决方案。
With the increasing complexity and integration of equipment,integration factors such as system integration faults and unit mutual test become prominent,which brings new problems to system-level testability allocation and design,such as the unreasonable testability index allocation caused by traditional methods without considering integration faults and unit mutual test,and the lack of system-level test selection methods for system-level testability design. The methods of testability index allocation and system-level test selection are proposed by analyzing the integration faults and unit mutual test caused by system integration,which provides a set of solutions for system-level testability design.
