Functional Safety for ISO 26262 and IEC 61508

Designers have now a simpler way to system-level functional safety design to achieve standards compliance.

To achieve functional safety, the risk of hazards caused by system malfunction must be removed. Safety standards ensure that associated risks are reduced or removed to meet safety requirement levels. The functional safety standards include IEC 61508 for the general industry and ISO 26262 for road vehicles.

These standards define the appropriate safety lifecycle and Safety Integrity Levels (SILs), develop hardware and software and provide a safety analysis with supporting confirmation measures and processes.

Functional Safety in your Market

Automotive

The automotive industry is under pressure to provide new and improved vehicle safety systems, ranging from basic airbag-deployment systems to extremely complex advanced driver assistance systems (ADAS) with accident prediction and avoidance capabilities. These safety functions are mainly carried out by electronics. The ISO 26262 has been developed to enable the design of electronic systems that can prevent dangerous failures or control them if they occur.

Our SafeAssure^® functional safety program is aligned with the international standards at the heart of automotive safety applications. This allows system engineers to design with confidence and efficiently achieve system-level compliance.

Industrial

Recent industrial disasters have highlighted the need for improved safety, and an increasing number of industrial control systems are requiring IEC 61508 safety certification.
