US-China trade: Trump administration orders chip design software firms to stop selling to China; Synopsys, Cadence among those hit

Trade War: In a significant escalation of its technology clampdown on China, the Trump administration has directed leading US companies offering electronic design automation (EDA) software to stop selling their tools to Chinese customers. The US Department of Commerce’s Bureau of Industry and Security (BIS) reportedly issued letters to EDA giants — including Synopsys, Cadence, and Siemens EDA — instructing them to halt exports of their software, crucial for designing advanced semiconductors.
