Empyrean / domestic EDA
China's EDA champions racing to replace Synopsys/Cadence
Empyrean Technology, with peers like Primarius and X-EPIC, leads China's push to build domestic EDA tools after Synopsys, Cadence and Siemens EDA were restricted from serving China (briefly in 2025). Full-flow domestic EDA for leading-edge nodes remains immature, keeping EDA a severe chokepoint for Chinese chip design.
