摘要
安全相关产品的硬件设计需满足硬件安全完整性要求、系统安全完整性要求以及检测到故障时对系统(产品)的行为要求。为满足硬件安全完整性的要求,给出了架构设计的方法和量化随机失效影响的方法。同时,对实现系统安全完整性要求和检测到故障时对系统(产品)的行为要求进行了阐述。
The hardware design of safety-related products shall meet the requirements of hardware safety integrity, system safety integrity, and the activities to the system （ product ） when failures have been detected. In order to satisfy the requirement of hardware safety integrity, the method of architectural design and the method to make quantification for influence of random failures are given. In addition, the requirements for implementing system safety integrity and the activities to the system （product） when failures have been detected are elaborated.
