What is Functional Safety?
Functional safety is a critical element for any system deployed within a vehicle, robot, factory, and beyond. It’s the system’s ability to detect, diagnose, and safely mitigate the occurrence of any fault, preventing harm to people and the environment. Arm’s portfolio of Safety Ready products and functional safety partnerships offer customers the solutions they need for their functional safety-related applications.
The Arm Safety Ready portfolio includes software test libraries (STL), which are software-based safety mechanisms that provide diagnostic capabilities for permanent faults. Download our white paper to learn about the steps and considerations when implementing STL for ISO 26262 ASIL B automotive applications and IEC 61508 SIL 2 industrial systems.
Arm Supports Functional Safety
To ensure the best outcomes for our technology and customers, Arm plays an active role in the development of international safety guidelines; for example, ISO 26262 and IEC 61508.
Arm products are designed “out of context” to satisfy the widest range of applications. We believe that everyone in the integrated circuit (IC) supply chain has an important role to play in safety certification, and applications must be certified in accordance with market-specific standards. Arm is capable of supporting customers and manufacturers in their certification processes of Arm-based devices.
Get Ready for a New Era of Compute
The crucial stepping-stones to enhance functional utility and human safety have arrived with the latest flexible, scalable heterogeneous compute solution from Arm. Learn how Arm provides the functional safety support, processing power and efficiency to enable the journey to autonomous.
The Arm Safety Ready Portfolio
The Arm Safety Ready portfolio is a collection of Arm products that have been through various and rigorous levels of functional safety systematic flows and development. It combines IP, safety features, tools, and robust methodologies to help reduce risk while fast-tracking the certification phase of projects.
