OrthoRoute: GPU-Accelerated PCB Autorouter for Complex Circuit Board Routing
By

Crisp on the outside, thoughtful on the inside. A keeper.
Summary
OrthoRoute is a GPU-accelerated PCB autorouter developed to solve the challenge of routing complex printed circuit boards with thousands of connections. The project was born from necessity when the creator needed to route a PCB with 16 connectors, 1,100 pins each, totaling 17,600 pads and 8,192 airwires. Traditional hand routing would take months, so the developer created this GPU-accelerated solution that leverages parallel processing to dramatically speed up the routing process. The article explains the technical approach, challenges faced, and the advantages of using GPU acceleration for PCB routing tasks.

· 3 pulledThis is a project born out of necessity. Another thing I was working on needed an enormous backplane. A PCB with sixteen connectors, with 1,100 pins on each connector. That's 17,600 individual pads, and 8,192 airwires that need to be routed.
Hand routing this would take months. For a laugh, I tried F
