According to information from Kuaitech on July 4th， Cadence Design Systems， one of the three major EDA giants， has officially announced that the United States has lifted its export restrictions on EDA to China.
Cadence Design Systems released a statement today regarding the lifting of recent U.S. export restrictions to China. The statement confirmed that the U.S. Department of Commerce’s Bureau of Industry and Security (BIS) has withdrawn the export restrictions specified in a letter issued on May 23， 2025. The company is now restoring access for affected customers to its software and technical support in accordance with U.S. export laws.
In addition to Cadence， the other two major EDA players， Synopsys and Siemens AG， have also successively issued statements indicating they have received notification from the U.S. BIS regarding the cancellation of export restrictions on chip design software to China. They are in the process of resuming supply and full customer support for recently restricted products in the Chinese market.
Previous reports indicated that the U.S. Department of Commerce’s Bureau of Industry and Security had sent letters in May to several leading Electronic Design Automation (EDA) suppliers， instructing them to cease shipments to Chinese customers and revoking previously granted shipping licenses for some suppliers.
The affected products not only included semiconductor design software but also related chemicals.
The lifting of U.S. export restrictions on EDA software to China by major industry players like Cadence， Synopsys， and Siemens marks a significant development. This move is expected to alleviate supply chain disruptions and allow Chinese chip designers to regain access to crucial tools that underpin advanced semiconductor manufacturing. EDA software is indispensable for the complex process of designing integrated circuits， from initial concept to final production. Restrictions on these tools can significantly impede the pace of innovation and the ability of companies to develop cutting-edge technologies. The prompt resumption of services by these EDA giants suggests an effort to quickly normalize business operations and meet the demands of the Chinese market， which is a substantial consumer of advanced technology. This policy adjustment by the U.S. government， if sustained， could signal a broader recalibration of export control strategies， potentially enabling more predictable international trade in critical high-tech sectors.
