Abstract

A new technique is elaborated for building combinational devices with fully self-checking structures, where any kind of single stuck-at faults in internal logical elements is detected. The suggested technique is based on searching for groups of combinational device outputs in which symmetrical errors are impossible (SI groups). When establishing such groups, the developer can choose the implementation options for a self-checking device, each of which assumes the use of a code for failure control with the detection of any unidirectional and asymmetrical errors (identified multiplicities included).

基于搜索对称独立输出的组的组合设备的完全自检结构的组织

摘要

精心设计了一种新技术，用于构建具有完全自我检查结构的组合设备，其中可以检测到内部逻辑元素中的任何类型的单一卡住故障。所建议的技术基于搜索不可能出现对称误差的组合设备输出组（SI组）。在建立此类组时，开发人员可以为自检设备选择实现选项，每个选项都假定使用代码进行故障控制，并检测任何单向和非对称错误（包括已确定的多重性）。
