Achieving ISO 26262 certification with ASIL ready IP

Designing automotive SoCs and supporting components such as semiconductor IP demands a parallel functional safety assurance process, rooted in a deep understanding of the requirements of ISO 26262, AEC-Q100 and subtle technical details such as the impact of various temperature profiles on the potential failure modes of an IP block.

This article from Tech Design Forum explores why achieving ISO 26262 certification for advanced driver assistance systems takes a combination of ASIL ready IP and rigorous development strategies.

How Formal Reduces Fault Analysis for ISO 26262 Safety Verification

The ISO 26262 standard defines straightforward metrics for evaluating the “safeness” of a design by defining safety goals, safety mechanisms, and fault metrics. However, determining those metrics is difficult because evaluating every possible fault is impractical on the size of today’s designs. Formal verification tools have an advantage over other approaches because formal tools have the unique ability to trace cones of influence and eliminate large numbers of irrelevant faults in a process known as fault pruning. Formal tools provide unique capabilities that are essential for any automotive functional safety flow.

Abdel Ayari, Digital Design & Verification Solutions Applications Engineer at Mentor Graphics discussed onhow formal reduces fault analysis for ISO26262 safety verificationat the DVClub Europe Conference- “Methodologies for Rigorous Safety Verification”, which took place on 28th November 2017.

Customising APIS IQ software for ISO26262 safety analysis – Closing the gap from concept to Verification

Complex designs achieve ISO26262 via the introduction of Safety Mechanisms to protect against random hardware faults that can cause a violation of a Safety Goal. The challenge is in performing a comprehensive safety analysis of the design, and proving the completeness of the analysis in an efficient manner.

Krishna Priya Chakiat Ramamoorthy from Infineon Technologies was at DVClub Europe Conference on 28th November 2017 and explained how APIS IQ features are innovatively used to identify the potential random hardware faults which can disrupt the function of a design, leading to a failure to meet a safety goal and provided a suggestion on how to link this conceptual analysis to design and verification plans, thus closing the gap between architecture and verification.

Formal fault analysis for ISO 26262 fault metrics on real world designs

Safety critical development processes, governed by standards such as ISO26262, include the use of fault correction components that protect the device against Random faults that occur naturally during operation. A methodology has evolved that makes use of fault simulation and formal techniques to establish the diagnostic coverage of safe faults, and detect dangerous faults. A significant remaining challenge is the debug of these dangerous faults. While fault simulation can establish fault propagation, Formal can produce a clear detection of dangerous faults, enable their debug, and indicate how a design may be protected against their occurrence.

Jörg Große, Product Manager Safety Critical Solution at OneSpin Solutions, discussed these dangerous fault debug techniques using state-of-the-art formal verification appsat the DVClub Europe Conference- “Methodologies for Rigorous Safety Verification” on 28th November 2017.
