根据功能安全的理论,对安全相关产品的实现过程进行了梳理.具体给出了实现安全相关产品的脉络,即如何将一个产品设计成满足安全完整性等级要求的安全相关产品.设计过程从结构上说,主要包括硬件实现和软件实现；从安全完整性来说,主要包括硬件安全完整性的实现和系统安全完整性的实现.%The implementing process of the safety related products is analyzed and summarized in accordance with the theory of functional safety.The main route of the implementation of safety related products is given specifically,i.e.,how to design a safety related product which meets the safety integrity level (SIL) requirements.From the structural viewpoint,it mainly includes hardware implementation and software implementation;while in respect of the safety integrity,it includes the implementation of hardware safety integrity and the implementation of system safety integrity.
