The U.S. government has rescinded its export restrictions on chip-design software to China, three of the largest players in the space announced on Thursday.
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.
