PCB Auto Router - Smart PCB Autorouter

PCB Auto Router is a local PCB routing software (PCB autorouter) that performs circuit board routing with GPU parallel computing. It reads a Specctra DSN file, generates traces according to your PCB design rules — board outline, layer stack, track width, clearance and vias — and exports a SES file you import back into your EDA tool for DRC checking.

It supports the DSN/SES workflow of KiCad, EasyEDA Pro and Altium Designer, with one-click routing plugins for KiCad and EasyEDA. Like Freerouting, it reads standard Specctra DSN files, so existing projects switch over directly — the difference is that routing runs in parallel on the GPU rather than on a single CPU thread, with native support for differential pair routing and length-matched serpentine traces. Every PCB file stays on your own computer and is never uploaded to a server.
