Introduction: The “Choke Point” of Core Industrial Software Seen Through the Lag of EAD The lag in the development of EAD (Electronic Design Automation) software is a microcosm of China’s constraints in the high-end industrial foundational software sector. It reveals two harsh realities: Gap in Technological Accumulation: Such software requires profound algorithmic accumulation, physical models, … Read more
STMicroelectronics’ SPSA068 is a power management integrated circuit (PMIC) that integrates a synchronous current mode BUCK step-down regulator (with built-in high and low side power MOSFETs) and a high-precision voltage reference. It is both flexible and easy to use, equipped with a complete set of features to meet the functional safety requirements of passenger vehicles, … 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
The automotive-grade MCU (Microcontroller Unit) serves as the core control chip in automotive electronic systems. Its development has a higher technical threshold, stricter quality requirements, and a longer lifecycle management compared to general consumer electronics MCUs. The following is a brief analysis from two aspects: development characteristics and industry prospects. 1. Characteristics of Automotive-grade MCU … Read more
