This white paper discusses how market trends, the need for increased productivity, and new legislation have accelerated the use of safety systems in industrial machinery. This TÜV-qualified FPGA design methodology is changing the paradigms of safety designs and will greatly reduce development effort, system complexity, and time to market. This allows FPGA users to design their own customized safety controllers and provides a significant competitive advantage over traditional microcontroller or ASIC-based designs. Introduction The basic motivation of deploying functional safety systems is to ensure safe operation as well as safe behavior in cases of failure. Examples of functional safety systems include train brakes, proximity sensors for hazardous areas around machines such as fast-moving robots, and distributed control systems in process automation equipment such as those used in petrochemical plants. The International Electrotechnical Commission’s standard, IEC 61508: “Functional safety of electrical/electronic/programmable electronic safety-related systems,” is understood as the standard for designing safety systems for electrical, electronic, and programmable electronic (E/E/PE) equipment. This standard was developed in the mid-1980s and has been revised several times to cover the technical advances in various industries. In addition, derivative standards have been developed for specific markets and applications that prescribe the particular requirements on functional safety systems in these industry applications. Example applications include process automation (IEC 61511), machine automation (IEC 62061), transportation (railway EN 50128), medical (IEC 62304), automotive (ISO 26262), power generation, distribution, and transportation. 图Figure 1.

ISO 26262《道路车辆功能安全》国际标准是针对总重不超过3.5吨八座乘用车，以安全相关电子电气系统的特点所制定的功能安全标准，基于IEC 61508《安全相关电气/电子/可编程电子系统功能安全》制定，在2011年11月15日正式发布。ISO 26262是史上第一个适用于大批量量产产品的功能安全（Functional Safety）标准。特别需要注意的是，ISO 26262仅针对安全相关电子电气系统，包含电机、电子与软件零件，不应用于非电子电气系统（如机械、液压等）。功能安全之设计议题在汽车领域已被重视，因其关系人员安全与公司商誉等问题，透过危害分析与风险评估（Hazard Analysis & Risk Assessment，HARA）及V模型设计架构，使功能安全需求等级得到一致性的分析结果，以利汽车电子系统之生命周期考虑到所需失效防止技术与管理要求，并借由设计开发、查证（Verification）及确认（Validation）等能力成熟度模型集成（CMMI-DEV）流程加以实现，使得产品之功能安全符合所需汽车安全完整性等级（ASIL）。
