American semiconductor designer faces large fine of $140 million due to business dealings with a Chinese military organization, allegedly supplying software believed to be used in nuclear explosion simulations
In a series of recent developments, two leading technology companies, Cadence Design Systems and Nvidia, have found themselves under the microscope for alleged violations of U.S. export controls.
Cadence Design Systems, a prominent Electronic Design Automation (EDA) tools provider, has pleaded guilty to sanctions violations related to exporting its EDA tools to sanctioned Chinese institutions. As a result, the company will pay a hefty $140 million in penalties and face probation that restricts dealings with sanctioned Chinese entities without proper export licenses.
The U.S. government lifted a general ban on exporting EDA tools, including those from Cadence, earlier in July 2025. However, companies must still obtain licenses to export to entities on the U.S. Entity List, such as China’s National University of Defense Technology (NUDT), which has been on the list since 2015 due to concerns over its activities being contrary to U.S. national security and foreign policy interests.
Meanwhile, Nvidia, a leading manufacturer of advanced AI chips, has faced scrutiny for black market smuggling of its products like the B200 and RTX 5090 into China despite official export restrictions. The U.S. government is increasingly pressuring allies such as Singapore and Malaysia to combat these smuggling rings. However, Nvidia’s AI chip technology still reaches China indirectly via partnerships with companies like Cadence, which integrate Nvidia’s Blackwell-powered AI design tools into their offerings.
This situation reflects a broader strategy where Nvidia avoids direct sales to sanctioned Chinese firms but enables the use of its hardware through third-party partners. Jensen Huang, Nvidia's CEO, has denied direct involvement in the smuggling of its chips.
The easing of U.S. export controls on AI chips and EDA tools to China in early July 2025, as part of broader trade negotiations between the U.S. and China, marked a tentative "chip war truce." However, strict prohibitions and enforcement remain for dealings with sanctioned Chinese military or strategic institutions, and major companies like Cadence and Nvidia continue to operate under heightened scrutiny and regulatory risk.
In addition to Cadence and Nvidia, Hunan Guofang Keji University, Central South CAD Center, and CSCC, affiliates and aliases of NUDT, have been added to the restricted list. The massive demand in China for these technologies makes smuggling them quite lucrative, and it is nearly impossible to stop the practice completely.
The court has also placed Cadence under probation for three years, preventing it from doing business with sanctioned institutions to avoid harsher penalties. The U.S. government has not taken any official action against Nvidia for the smuggling of its AI chips.
As the tech industry navigates these complexities, the U.S. government is tightening its grip on export controls, aiming to ensure that sensitive technologies do not fall into the wrong hands. This issue is particularly significant in the context of China's technological development.
The financial penalty for Cadence Design Systems, following their guilty plea for sanctions violations, amounts to $140 million. Despite the U.S. government easing export controls on AI chips and EDA tools to China, Nvidia's AI chip technology still indirectly reaches China through partnerships, heightening regulatory risk.
