For context, EDA (electronic design automation) is the software backbone of chip and circuit design. Trump 2.0 tried to cut China off from it in March, forcing Cadence, Synopsys, and Siemens to halt China sales. But just weeks later, Washington quietly reversed course and lifted the ban. Then last week, Trump said the U.S. will impose export controls on “any and all critical software,” so assume EDA again. Turns out a secret team in Shenzhen had already created a solution: every core component, every bit of IP, all built domestically.
