Synopsys Halts China Sales Due to U.S. Export Restrictions

Synopsys, a leading U.S. semiconductor design software firm, has ceased all sales and services in China, effective May 29, 2025, in compliance with newly imposed U.S. export restrictions. An internal memo reviewed by Reuters indicates that the U.S. Department of Commerce’s Bureau of Industry and Security has mandated the cessation of such exports without licenses, which are now being revoked in many cases. These restrictions cover semiconductor design software and certain chemicals.

Key Points:

• Immediate Action Taken: Synopsys has halted all sales and services in China and stopped accepting new orders. Access to its customer support portal, SolvNetPlus, has also been restricted for Chinese clients.
• Scope of Restrictions: The measures affect all Chinese customers, including employees of global firms working within China and Chinese military users worldwide.
• Impact on Business Operations: Synopsys has suspended its financial forecasts amid the uncertainty, as the move could significantly impact China’s chipmaking capabilities, which heavily rely on advanced U.S. electronic design automation (EDA) tools.
• Market Position: Synopsys, along with Cadence and Siemens EDA, dominates over 70% of China’s EDA market.

This development underscores the growing tensions between the U.S. and China over technology exports and the potential ramifications for global semiconductor supply chains.
