New provisions for Parts 11 and 12 include automotive semiconductors and motorcycles.
The semiconductor industry needs a common interpretation of functional safety.

An opportunity has been created to actively promote the ISO26262 2nd edition , which will be officially released in May next year, to domestic semiconductor companies. The second revision expands the scope of application to the semiconductor sector, requiring a response from the automotive industry.

On the 26th, the 'ISO26262 2nd Automotive Semiconductor Safety Design International Standard Guideline Semiconductor Semiconductor Safety Design ...

Jeong Dong-hee, President of the Korean Agency for Technology and Standards, stated, "Domestic standard proposals are significantly stagnant. Looking at the IEC and ISO, the number of domestic standard proposals has been declining since 2009." He also addressed the need for standards, saying, "In the era of the Fourth Industrial Revolution, we need to prioritize standards rather than follow suit."

He said, “The National Institute of Standards and Technology will play a proactive role in promoting standards. He added, “We will create an environment where companies, academia, and others can strategically create standards,” and “We will supplement it with the Korean Industrial Standards (KS) standard in line with the publication of the second edition of ISO 26262, and we will continue to provide education to related companies.”

The second revision of ISO 26262 includes some revisions to existing Parts 1 through 10, while new Parts 11 and 12 are established. Part 11 covers automotive semiconductor guidelines, and Part 12 includes motorcycle guidelines.

In the automotive semiconductor sector, "safety analysis" guidance has been refined, providing failure modes and potential causes. The "emergency operational time interval" defines the time between a failure and the arrival of a safe state, during which safety must be ensured. It also provides guidance on IP design verification, basic failure rate estimation, and fault injection testing, and includes technically helpful content on fault control for digital and analog components.

Kim Dong-ho, a director at the Korea Agency for Technology and Standards, said, "To respond to the second edition of ISO 26262, experts are participating in international standardization meetings and sharing the results with the industry. We are promoting the revision of KS R ISO 26262 and disseminating it. We are also establishing a foundation for testing and evaluation."

“Part 11 is an unprecedented standard created to address the need for a commonly understood interpretation of functional safety in the semiconductor industry,” said Koh Byeong-gak, a senior researcher at the Korea Testing Laboratory (KTL). “It should be noted that this is not a requirement. “It is to provide information on how to apply it,” he explained.

Kwon Young-soo, head of the processor research group at the Electronics and Telecommunications Research Institute (ETRI), introduced Aldebaran, a self-developed processor for autonomous vehicles, and said, “The core of ISO26262 is detecting faults and analyzing the safety mechanisms created to detect them.” He added, “In order to move towards autonomous vehicles, functional safety that goes beyond fault detection is necessary.”

In the afternoon, representatives from Qualcomm, Infineon, Renesas, Texas Instruments, NXP, Mentor Siemens, Synopsys, Hyundai Motor Company, and SK Hynix appeared and discussed how the industry is responding to ISO26262.
