摘要
针对工程中各种可测性设计方法与规定的诊断要求间缺乏定量关系,造成一定的设计的盲目性等问题,以产品的故障模式集及其相关特性为基础,界定了充分度的概念,构建了充分度的数学模型,并将其与目前工程中常用的故障检测率/故障隔离率要求建立了定量关系,提出了一套以充分度为基础的可测性设计理论,并且给出基于该理论的可测性设计流程。
Considering the absence of quantitative relation between various design for testability (DFT) methods and certain diagnosis requirements, which results in the blindness in DFT field, based on the product' s fault mode aggregation and its relative characteristic, the sufficient measure concept is established, and its mathematics model is illustrated, and the quantitative relation between it and the general testability requirements(FDR/FIR) is set up. The theory on DFT based on the sufficient measure is offered and the design flow is brought forward.
