China's IC design boom nears CNY1 trillion, but Nvidia CUDA gap exposes limits

China's IC design sector nearing RMB1 trillion in output masks a fragile foundational ecosystem. Technically, the absence of a native AI compute architecture perpetuates CUDA dependency, throttling large model training efficiency and stifling upstream innovation in EDA and advanced packaging. On compliance, escalating U.S. export controls force costly supply chain overhauls—operational expenses surge over 30%, with sub-7nm nodes nearly entirely reliant on foreign IP and equipment. Strategically, NVIDIA is deepening its moat via Grace-Hopper superchips and AI factories, locking customers into full-stack dominance, while TSMC (Taiwan, China) expands CoWoS capacity to cement irreplaceability in high-end AI manufacturing. Over the next 12–24 months, without breakthroughs in compilers, distributed schedulers, and operator libraries, this trillion-yuan milestone risks becoming a hollow metric of low-value design outsourcing, leaving high-margin AI silicon firmly under foreign control.
