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. 圖Figure 1.

ISO 26262《道路車輛功能安全》國際標準是針對總重不超過3.5噸八座乘用車,以安全相關電子電氣系統的特點所制定的功能安全標準,基于IEC 61508《安全相關電氣/電子/可編程電子系統功能安全》制定,在2011年11月15日正式發布。ISO 26262是史上第一個適用于大批量量產產品的功能安全(Functional Safety)標準。特別需要注意的是,ISO 26262僅針對安全相關電子電氣系統,包含電機、電子與軟件零件,不應用于非電子電氣系統(如機械、液壓等)。功能安全之設計議題在汽車領域已被重視,因其關系人員安全與公司商譽等問題,透過危害分析與風險評估(Hazard Analysis & Risk Assessment,HARA)及V模型設計架構,使功能安全需求等級得到一致性的分析結果,以利汽車電子系統之生命周期考慮到所需失效防止技術與管理要求,并借由設計開發、查證(Verification)及確認(Validation)等能力成熟度模型集成(CMMI-DEV)流程加以實現,使得產品之功能安全符合所需汽車安全完整性等級(ASIL)。
