China’s EDA champion buys start-up to address weak link, support Huawei’s Tau Scaling Law

Empyrean Technology, China’s top provider of electronic design automation (EDA) tools, plans to acquire a majority stake in a domestic start-up, reinforcing Beijing’s drive for tech self-sufficiency and bolstering support for Huawei Technologies’ semiconductor ambitions.

The Beijing-based firm said in a Shenzhen Stock Exchange filing on Sunday that it would acquire a 50.38 per cent stake in Easy-Logic Technology for 218.8 million yuan (US$33 million). Once completed, the start-up would be consolidated into Empyrean’s financial statements.

Founded in 2021, Shenzhen-based Easy-Logic develops logic optimisation tools that help chip designers reduce iteration time and resource requirements. The start-up’s algorithms had won international EDA competitions and its products were used by nearly 100 digital chip design firms across the globe, according to Empyrean.

The acquisition underscores the urgency of China’s campaign to develop local alternatives to critical foreign technologies. Microchip development relies on EDA software, a market long dominated by three Western players: Synopsys, Cadence Design Systems and Siemens EDA.

As Washington tightens tech export controls on advanced technologies, Beijing has pressed domestic champions – including Empyrean, Primarius Technologies and Semitronix – to close the technological gap with global rivals.

Empyrean noted in the filing that logic optimisation had become increasingly important to chip design as manufacturing processes advanced and the industry adopted Huawei’s Tau Scaling Law.

Unveiled earlier this year, Huawei’s chipmaking methodology aims to achieve transistor performance equivalent to an advanced 1.4-nanometre process node by 2031, reducing reliance on cutting-edge lithography equipment currently blocked by US export curbs.

The framework places higher performance demands on EDA software, creating pressure on domestic suppliers to upgrade their tools.

Empyrean said the acquisition would boost its next-generation artificial intelligence and three-dimensional integrated circuit design (3D IC) capabilities by integrating Easy-Logic’s engineering talent and intellectual property.

The company has emerged as a key backer of Huawei’s road map. In May, Empyrean unveiled Argus, a physical verification platform for 3D IC design that it described as a “key carrier” for implementing the Tau Scaling Law.

Empyrean had also integrated AI-optimised algorithms and agentic tools into its software suite, slashing the time needed for circuit layout tasks from four weeks to one week, chairman Liu Weiping said in September.
