官方科普：TapeOut 类比芯片分层抽象Official Explainer: TapeOut Mirrors Chip Design Layering
官方科普以芯片设计的分层抽象类比 TapeOut：门电路组成半加器，半加器组成全加器，全加器组成加法器，加法器进入处理器，芯片设计正是靠分层达到数十亿晶体管；每一层只需知道下一层的输入输出，而不需要了解其内部如何连线，TapeOut 采用同样的方式。An official explainer compares TapeOut to the layered abstraction of chip design: gates make a half adder, half adders make a full adder, full adders make an adder, and adders go into a processor — that is how chip design reaches billions of transistors. Each layer only needs to know the inputs and outputs of the layer below, not how it is wired inside. TapeOut, the post says, works the same way.
