Xiaomi’s $56 Million Chip Ambition Crushed by Sudden U.S. Sanctions—XRING O1 at Risk of Collapse

Xiaomi, China’s largest smartphone maker, has hit a serious roadblock. The company’s big step into designing its own advanced chips is now threatened by new restrictions from the United States government.

Last month, Xiaomi unveiled its XRING O1 chip — the company’s first mobile processor designed in-house. This chip is manufactured using TSMC’s most advanced 3-nanometre process, the same cutting-edge technology used by Apple. Xiaomi planned to use this chip in its latest premium smartphones, marking a bold move toward building more of its technology internally.

But now, a new order from the U.S. Commerce Department’s Bureau of Industry and Security (BIS) is changing the game. The agency has told American electronic design automation (EDA) companies — including major players like Synopsys and Cadence — to stop supplying their software tools to Chinese firms. These tools are essential for designing chips like Xiaomi’s XRING O1.

What EDA Tools Do and Why This Matters

EDA tools are used to create blueprints for chips before they are physically made. Without them, chip designers can’t build, simulate, or test the complex layouts needed to produce modern processors. It’s like trying to design a skyscraper without any architectural software.

Xiaomi used EDA tools made by U.S. companies to design the XRING O1 chip. But with the new restrictions, those tools will no longer receive updates or support if used by Chinese firms. This could freeze Xiaomi’s ability to improve or even maintain its custom chip designs in the future.

Though the XRING O1 is currently used in a limited number of devices, insiders say Xiaomi wants to roll out its chips across all its future high-end smartphones and tablets. The ban may now delay or disrupt those plans.

The rules don’t cancel existing licenses, so tools already bought can still be used — but without updates, they will quickly become outdated. In chip development, where technology moves fast, that can be a major setback.

Other Chinese Tech Companies in the Crosshairs

Xiaomi isn’t alone. Several other Chinese tech firms are also affected.

Lenovo, the world’s largest PC maker, relies on U.S. EDA software to design its chips. Bitmain, a major supplier of cryptocurrency mining machines, is in a similar position. Both companies use TSMC to manufacture their custom processors and depend on U.S.-origin software to develop new designs.

Alibaba and Baidu, two of China’s biggest internet firms, have also started designing their own chips in recent years. Though the full effect of the new ban on them is not yet known, they too have relied on American design software to develop semiconductors for cloud computing and AI.

Meanwhile, Huawei — another tech giant previously targeted by U.S. sanctions — has been developing its own EDA tools as a workaround. But for companies like Xiaomi that have just begun investing in chip design, building new tools from scratch would take years and enormous resources.

The Financial Times reports that this latest move could seriously slow down China’s efforts to catch up in the semiconductor race. While some exceptions had previously allowed Chinese companies to make consumer-grade chips with help from TSMC and U.S. software, those paths are now closing.
