According to Xinzhijia: As the automotive industry advances towards intelligence, the number of electronic/electrical systems installed in vehicles continues to increase. Public data shows that a high-end luxury car can have more than 70 electronic control units (Electronic Control Unit, ECU), among which the engine management system, chassis control system, and braking system are all … Read more
People often ask me how to conduct functional safety testing and what the differences are compared to previous testing methods. I believe there isn’t much difference, but I place significant emphasis on Fault Injection Testing (FIT). This testing method is mentioned in Part 4 and Part 6, generally requiring ASIL to be ++. In fact, … Read more

In the automotive manufacturing industry, the reliability requirements for automotive grade chips are undoubtedly higher than those for commercial and industrial grade chips. As the name … Read more
The “independence” of the built-in watchdog in MCUs is typically reflected in its hardware isolation from core processing units (such as CPUs and buses), for example, having independent clock sources, counters, and reset logic. This ensures that even if the CPU becomes unresponsive due to software bugs or hardware failures, the built-in watchdog can still … Read more
