Moore's Law has been a cornerstone of the rapid advancement of digital technology over the past decades, although it is now confronting physical limits and diminishing economic returns.

过去几十年，摩尔定律一直是数字技术快速进步的基石，尽管如今它正面临物理极限和边际收益递减的挑战。

For an industry conditioned to equate progress with nanometers, the Tau Scaling Law disclosed by Huawei on Monday is a challenge to the organizing logic of the semiconductor ecosystem.

对于一个习惯于用纳米衡量进步的行业而言，华为5月25日公布的“τ scaling law”（陶缩放定律）无疑是对半导体生态系统运行逻辑的一次挑战。

Instead of continuing the increasingly expensive race to shrink transistors, Tau Scaling proposes that future chip performance gains can come from compressing the signal propagation time through architectural and timing innovations. Huawei has set a target of reaching a chip density equivalent to 1.4 nanometers by 2031.

陶缩放定律提出，摒弃代价日益高昂的晶体管微缩竞赛，转而通过架构与时序创新压缩信号传播时间，驱动未来芯片性能提升。华为已设定目标，到2031年实现相当于1.4纳米制程的芯片密度。

Washington's export restrictions have attempted to cut China off from advanced lithography equipment, leading-edge foundries and portions of the global event-driven architecture software stack. Such measures were designed to slow China's progress in advanced semiconductors.

美国的出口限制试图将中国排除在先进光刻设备、前沿代工厂以及部分全球事件驱动架构软件栈之外。这些措施旨在减缓中国在先进半导体领域的进步。

That is where Tau Scaling enters the picture. Instead of shrinking transistor dimensions from 3 nm to 2 nm and beyond, Huawei is extracting more performance from mature process nodes such as 5 nm and 7 nm by means of architectural optimization, timing compression, logic folding and system-level coordination.

这正是陶缩放定律发挥作用的地方。华为不再追求从3纳米到2纳米及更小尺寸的晶体管微缩，而是通过架构优化、时序压缩、逻辑折叠和系统级协调等手段，从5纳米、7纳米等成熟工艺节点中挖掘更多性能。

Much of the underlying research — including asynchronous computing concepts, wave pipelining, and timing optimization techniques — can be traced back decades. What Huawei has done, under conditions where the traditional scaling route became inaccessible, is to revisit those ideas, combine them, enhance them and industrialize them.
