[Huawei Huang Yu: The biggest challenge of Tao's Law lies in EDA tools] "Science and Technology Innovation Board Daily" reported on the 15th that Huang Yu, chief scientist of Huawei Semiconductor EDA, said today at the 2026 Bay Chip Exhibition that Huawei's Tao's Law is mainly divided into four layers: the most basic device layer, optimizing the transistor structure and interconnection method , compressing the device time constant from the source; the second layer is the link layer, which is our biggest innovation point; the third layer is the chip layer, where software and hardware are co-designed to form a new architecture; the fourth layer is the system layer, which is the well-known super node and cabinet interconnection, which requires better communication protocols and faster speeds. He said, "The biggest challenge of Tao's Law lies in EDA tools. At the same time, process challenges, engineering challenges and system design challenges also exist."
