Cadence Design Systems and Synopsys shares tumbled Wednesday after the Trump administration told the chip design software firms that they can no longer sell to Chinese groups. The move is the latest attempt by the U.S. government to stop China from developing advanced semiconductors.
The U.S. Commerce Department told the electronic design automation firms to stop supplying their technology to China, the Financial Times reported. Companies contacted included Cadence, Synopsys and Siemens EDA, a unit of German conglomerate Siemens.
On the stock market today, Cadence stock fell 10.7% to close at 288.61. Synopsys stock dropped 9.6% to 462.43.
Last month, President Donald Trump effectively barred chipmakers Nvidia and AMD from selling even throttled AI processors to Chinese customers.
The U.S. government previously blocked semiconductor equipment manufacturers from selling advanced gear to China. That includes Dutch lithography giant ASML.
U.S. officials are worried about Chinese firms using U.S. technology for military purposes.
