In the entire semiconductor industry chain, there is a significant gap in areas such as EDA, manufacturing, and key equipment like photolithography machines compared to the world’s advanced levels; in terms of design, the gap in mobile processors is relatively small compared to international standards, while desktop CPUs and GPUs show a clear gap, and … Read more
The LCD screen is JM12864 or FYD12864 (with font library). I have used both models without issues. 4 rows * 8 columns of Chinese characters = 32 serial communication interfaces P1.5–P1.7, which can be modified according to your circuit. #include #define uchar unsigned char void LCD_ini(); void ascii_change(void); void delay(); void wri_add(uchar com); void wri_dat(uchar … Read more
Chip design and verification are facing increasing challenges. How to address these issues—especially in the context of incorporating machine learning—is a major concern for the EDA industry, which was a common theme among the four keynote speakers at this month’s Design Automation Conference (DAC). This year, DAC returned as an in-person event, featuring keynote speeches … Read more
1. The SPI rate must not exceed 15M; exceeding this will result in serious bit errors. 2. If the reception method is interrupt-based, the SpicCR character length control bit determines the length of the interrupt. For a length of 8, with interrupt priority 1, an interrupt is generated for each byte received. For a length … Read more
With the stagnation of Moore’s Law and system-level enterprises beginning to attempt to create their own chips, EDA and IP vendors seem to know that their spring has arrived—because their customer base has expanded. However, for EDA/IP vendors, there remains a massive obstacle in front of them: the complexity and high threshold of chip design … Read more
The global semiconductor industry has entered a super cycle. China-U.S. technology friction. China’s integrated circuit industry support policies are strengthening, etc. Multiple factors overlap. The outlook for the chip industry is promising. First, let’s clarify the concepts and differences between “semiconductor,” “chip,” and “integrated circuit”, in general, semiconductor, integrated circuit, and chip can be considered … Read more

The demand for the global chip market continues to … Read more
Source: Synopsys Technology Zhihu, thank you! Chips, as the core components of modern electronic products, have always played the role of the “brain”. They are extremely technology-intensive and capital-intensive, with production lines often costing tens to hundreds of billions of dollars. The complete process of chip manufacturing includes several main stages: chip design, wafer manufacturing, … Read more
Source: Content from Mo Shang Feng Qi Lu Kan IC, thank you.. With the support of various parties, integrated circuits have become a hot topic of the era, with numerous articles discussing the complexity and difficulties of chip design. The old donkey plans to review the chip design process from the perspective of EDA usage. … Read more
Source: Content from IP and SOC design, thank you! @Mark: The biggest change in the past decade is low power design. Ten years ago, low power design mainly focused on reducing dynamic power, employing various clock gating techniques, and preventing unused modules from toggling. In the last ten years, static power leakage has become a … Read more
