U.S.-China tech tensions have seen an abrupt escalation since President Donald Trump issued an order mandating American electronic design automation (EDA) software companies, including Cadence Design Systems, Synopsys and Siemens EDA that control about 80% of China’s EDA market (the Guardian +4

U.S. Commerce Department’s Bureau of Industry and Security sent letters to these companies instructing them to suspend providing software products to Chinese clients. Although the Department would not comment directly, it did confirm a review of exports critical to national security – in some instances suspending existing licenses or adding requirements pending its review (Wall Street Journal/Reuters).

This directive seeks to thwart China’s development of sophisticated semiconductors for artificial intelligence (AI) and military use, using EDA tools vital in designing and manufacturing advanced chips. Restricting their access could have serious repercussions for China’s semiconductor industry.

Cadence and Synopsys shares experienced immediate financial repercussions following the announcement, dropping 10.7% and 9.6%, respectively, before recovering some ground after market close.

Synopsys said that it had not received any official notice from the Commerce Department and reaffirmed its 2025 revenue outlook, according to CEO Patrick Coughlan during an analyst call. BIS “has not provided us with any notice,” Coughlan claimed in response. Reuters and WSJ both report this news item.
The policy shift marks part of President Trump’s larger strategy to limit China’s access to critical technologies, with earlier measures including restrictions on Nvidia and AMD exporting advanced AI chips to China. Nvidia CEO Jensen Huang has spoken out against these export controls as being detrimental to U.S. leadership in AI as they accelerate domestic innovation while diminishing U.S. influence in one of the world’s largest AI markets (The Times/WSJ, 1 May).
Industry analysts express concern that China’s restrictions may have unintended repercussions. By restricting China’s access to U.S. technology, this may encourage Beijing to develop domestic alternatives instead; potentially leading to an improved Chinese tech sector and greater independence.
The new restrictions also raise questions about the global semiconductor supply chain. U.S. companies such as Synopsys and Cadence derive significant amounts of their revenue from China — about 16% and 12% respectively– so their loss would have far-reaching repercussions for global tech.

As the U.S. steps up its efforts to restrict China’s technological development, international community members closely observe. Their consequences could have profound ramifications on global trade, tech development and geopolitical relations.
The Trump administration’s directive represents an historic turning point in U.S.-China tech relations, signaling an aggressive new approach towards managing critical technologies and shaping global semiconductor development.
