U.S. lifts chip software curbs on China in sign of trade truce
The U.S. government has rescinded its export restrictions on chip design software to China, U.S.-based Synopsys announced.
In separate statements, semiconductor software designers Siemens AG, Synopsys, and Cadence all said they received letters from the U.S. Department of Commerce informing them that the controls had been lifted.
While Siemens is based in Germany, its chip design software subsidiary, Siemens EDA, is based in Oregon, U.S.
As a result of export control reversal, Siemens said it had "restored full access" to the recently restricted software and technology and had resumed sales and support to Chinese customers.
Synopsys and Cadence both said that they were working on doing the same. The U.S. Commerce Department did not immediately respond to a request for comment from CNBC.
The U.S. had informed the chip design software companies on May 23 that they were required to obtain licenses before exporting software and other technology for semiconductors to China. It followed an earlier tightening of export controls on other semiconductor products, which restricted the sales of advanced AI processors from Nvidia and AMD to China.
Shares of Synopsys and Cadence each climbed about 3% Thursday.
