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

China's leading electronic design automation (EDA) tool provider, Empyrean Technology, has announced plans to acquire a majority stake in Easy-Logic Technology, a domestic start-up. The 50.38% stake purchase, valued at 218.8 million yuan (US$33 million), was disclosed in a Shenzhen Stock Exchange filing on Sunday. The start-up, founded in 2021, specializes in logic optimisation tools that can help chip designers reduce iteration time and resource requirements.

Easy-Logic's algorithms have earned international EDA competitions and are utilized by nearly 100 global digital chip design firms. The acquisition is expected to strengthen Beijing's drive for tech self-sufficiency and provide additional support for Huawei Technologies' semiconductor ambitions. As Washington tightens tech export controls on advanced technologies, China has been encouraging domestic champions, such as Empyrean, Primarius Technologies, and Semitronix, to narrow the technological gap with global rivals.

The acquisition of Easy-Logic will bolster Empyrean's AI and 3D integrated circuit design capabilities by integrating the start-up's engineering talent and intellectual property. This move aligns with Huawei's Tau Scaling Law, a chipmaking methodology unveiled earlier this year aiming to achieve transistor performance equivalent to an advanced 1.4-nanometre process node by 2031.

The framework increases demands on EDA software, placing pressure on domestic suppliers to upgrade their tools.
