On July 16, 2025, the internationally recognized certification body DNV officially awarded the ISO 26262 Functional Safety Management System ASIL D certificate to Zhejiang Qiusuo Software Technology Co., Ltd. (Qiusuo Software).
This milestone confirms that the independently developed MBD Quality Suite toolchain fully complies with the ISO 26262 functional safety standard in both its development process and management system. It demonstrates the toolchain’s high reliability, enabling users to confidently employ it for safety-critical tasks under the ISO 26262 framework and providing solid safety assurance for model testing in automotive electronic systems.
Qiusuo Software has received the ISO 26262 ASIL D certificate issued by DNV.
ASIL (Automotive Safety Integrity Level) is a key metric within ISO 26262 for defining the stringency of safety requirements, categorized into four levels: A, B, C, and D.
ASIL D represents the highest safety level, applicable to system functions that could lead to severe or fatal hazards (e.g., powertrain control, advanced braking systems).
Passing the ASIL D certification signifies that the independently developed MBD Quality Suite software toolchain by Qiusuo Software has fully met the ISO 26262 functional safety standard requirements in both its development process and management system. This proves the toolchain itself possesses an extremely high level of confidence, allowing users to place significant trust in its correct execution of safety-critical tasks in compliance with the ISO 26262 standard, thereby providing solid safety assurance for model testing in automotive electronic systems.
