标准范围

本文件描述了一个功能安全框架，以允许使用预先存在的软件架构元素，这些元素最初不是根据ISO 26262:2018系列开发的，但旨在通过以下方式集成到符合ISO 26262:2018系列的安全相关嵌入式软件中:—？当使用所述预先存在的软件架构元素作为安全相关嵌入式软件的安全相关元素时，确定相关标准；—？确定预先存在的软件架构元素固有的相关标准，例如，需要外部安全机制来检测和控制由预先存在的软件架构元素引起的故障；—？为使用预先存在的软件架构元素提供合适的证据和论据，其可以包括适用的程序、技术和安全措施；—？当使用预先存在的软件架构元素作为安全相关嵌入式软件的安全相关元素时，支持满足软件安全要求；—？支持预先存在的软件架构元素作为安全相关嵌入式软件的安全相关元素的集成。

This document describes a framework for functional safety to enable the use of pre-existing software architectural elements not originally developed in accordance with the ISO 26262:2018 series, but intended to be integrated into safety-related embedded software conformant with the ISO 26262:2018 series by:

—     determining relevant criteria when using the pre-existing software architectural element as a safety-related element of safety-related embedded software;

—     determining relevant criteria inherent to the pre-existing software architectural element, e.g. needs for external safety mechanisms to detect and control failures caused by the pre-existing software architectural element;

—     providing suitable evidence and arguments for use of the pre-existing software architectural element that can include applicable procedures, techniques and safety measures;

—     supporting the fulfilment of software safety requirements when using the pre-existing software architectural element as a safety-related element of safety-related embedded software;

—     supporting the integration of the pre-existing software architectural element as a safety-related element of safety-related embedded software.
