Networks-on-Chip, Chiplets, and UCIe Die-to-Die Interconnects: Mesh and Torus NoCs, Wormhole Routing, UCIe Protocol Stack, Reticle Limits, and Wafer-Scale Engines

Deep End Era. Engineering with Sankalp · Oct 29, 2026 · 1h 6m

A modern EUV lithography scanner can only print a rectangle 26 by 33 millimeters—858 square millimeters—and a single microscopic dust defect ruins an entire monolithic giant chip. We trace how computer architecture broke through the reticle wall, from Dally's Networks-on-Chip, wormhole routing, and virtual channels to chiplet yield economics, CoWoS/EMIB/3D hybrid bonding, the UCIe standard, and wafer-scale computing.
