China’s AI system builds Intel-class chips with zero US software

China has developed an AI-powered chip design system called QiMeng, created by the Chinese Academy of Sciences and affiliated institutions, to accelerate semiconductor development and reduce reliance on Western software amid escalating US-China tech tensions. QiMeng uses large language models to automate complex chip design tasks, significantly shortening development times—for example, producing an autonomous-driving chip in days instead of weeks. The platform is structured in three layers, integrating processor models, design agents, and chip design applications to support automated front-end design, hardware description language generation, OS configuration, and compiler toolchain creation. Researchers have already built two processors with QiMeng: QiMeng-CPU-v1, comparable to Intel’s 486, and QiMeng-CPU-v2, similar to Arm’s Cortex A53. The launch of QiMeng directly responds to US export restrictions that limit Chinese access to leading electronic design automation (EDA) software from companies like Synopsys, Cadence, and Siemens EDA, which previously dominated China’s EDA market. By open-sourcing QiMeng and publishing detailed documentation, China aims to improve design efficiency, reduce costs, and enable rapid customization of chip architectures and software stacks. While China still faces challenges in fabrication technology and ecosystem diversity, QiMeng represents a strategic step toward automating the full chip design and verification process and advancing China’s broader goal of semiconductor self-reliance in the face of ongoing geopolitical pressures.
