China’s chip design software firms back Huawei’s new scaling law. But can they catch US rivals?
Chinese chip-design software firms are lining up behind Huawei’s Tau Scaling Law, but analysts say overtaking US rivals will be hard.

Huawei’s Tau Scaling Law is drawing support from Chinese EDA vendors such as Empyrean and from researchers at Peking University. The pitch is a 3D chip design approach that could sidestep Western lithography limits, though the article says US dominance remains difficult to dislodge.
Huawei is trying a new way to build chips by stacking parts upward like a tall building instead of only making them smaller. Chinese software firms like the idea, but the article says beating the big US chipmakers still looks very hard.
Analysis
What is being proposed
Huawei’s new Tau Scaling framework is presented as an alternative to Moore’s Law. Instead of relying mainly on smaller transistors, it tries to improve chip performance by reducing the distance signals must travel across the system. The article says this is done by stacking flat circuits into vertical 3D structures through a method Huawei calls LogicFolding.
Who is backing it
The biggest recent endorsement in the article comes from Empyrean Technology, a major Chinese electronic design automation company. It has introduced Argus, a physical verification platform for 3D IC design, and says 3D IC technology is a key part of implementing Huawei’s approach. The article also points to a Peking University team that says it built a prototype EDA tool using a “true-3D” method compatible with LogicFolding.
Why it matters for China
The article frames this as part of a broader Chinese effort to build chipmaking tools and methods that do not depend on the most advanced Western lithography equipment. That equipment is constrained by US sanctions, so Huawei’s proposal aims to improve performance without needing the same manufacturing path used by leading global chipmakers.
The main caveat
Even with the new support, the article stresses that catching US rivals is not simple. Analysts warn that breaking the market dominance of US chip design software and related ecosystems will be a long and difficult process. The enthusiasm around Huawei’s architecture is real, but the article treats it as an early step rather than proof that China can quickly match the global leaders.
Key points
- Empyrean Technology backed Huawei’s Tau Scaling Law with a new 3D IC verification platform called Argus.
- Huawei’s framework shifts chip progress toward 3D stacking and signal-path compression rather than only shrinking transistors.
- Peking University researchers claimed a prototype EDA tool compatible with Huawei’s LogicFolding architecture.
- The approach is meant to reduce reliance on advanced Western lithography equipment restricted by US sanctions.
- Analysts in the article say breaking US dominance in chip design software remains a steep challenge.
If the 3D chip-design approach works, Chinese firms could build faster chips without relying as much on the most advanced Western manufacturing tools. That would strengthen domestic chip software and hardware efforts and give Huawei-backed methods a bigger role in future chip development.
The article says US rivals still dominate the market, so support for Huawei’s idea does not mean China can quickly close the gap. Even with technical progress, the ecosystem, tooling, and manufacturing challenges around advanced chip design could keep the approach from scaling fast.
