Abstract：As electronic products become an integral part of daily life, their application in safety-critical automotive systems has become ubiquitous. The International Organization for Standardization (ISO) 26262 standard outlines guidelines for establishing a good safety level in automotive System-on-Chips (SoCs). However, despite adherence to this standard, operational failures may still occur, necessitating Safety Mechanisms (SMs) to … Read more
Editor’s Note In the development of electronic control systems for smart vehicles, functional safety verification faces significant challenges: traditional fault injection testing methods are inefficient, lengthy, and costly, and they struggle to comprehensively cover the various abnormal scenarios required by the ISO 26262 standard (such as ASIL D level). As the complexity of automotive electronic … Read more
Recently, Unisoc’s next-generation THA6 series MCU has passed the evaluation by the internationally recognized certification body SGS regarding functional safety development processes and functional safety product design, obtaining two qualifications: the ASIL D level functional safety process certification compliant with ISO 26262 standards and the functional safety ASIL D Ready product certification, making it the … Read more
01 Introduction to Fault Injection Methods In critical scenarios related to functional safety, intensive testing activities are essential to ensure that new systems and built-in fault tolerance mechanisms operate as expected. Ensuring that the system operates normally in the event of a failure (Fail Operational) is a more complex issue than traditional testing content. The … Read more

1. Understanding Automotive Chips According to their functions, automotive-grade chips can be categorized into four types: computing and control chips, power chips, sensor chips, and others. Computing and control chips mainly consist of microcontrollers and logic ICs, primarily used for calculation, analysis, and decision-making; power chips mainly convert electrical energy and control circuits; sensor chips … Read more
Today, I am sharing an article explaining automotive-grade chips. The article is quite long, so you can save it for a slow read. What is Automotive Grade (commonly referred to as automotive-grade)? It is consistent reliability. The moment the car engine starts, it must work in the scorching heat of summer and the freezing cold … Read more
