AI Auto Layout, Now Faster, Cleaner, and More Manufacturable

In this video, we explain how AI Auto Layout in Flux works, why it produces more human-like results than traditional autorouters, and how to set up your board to get the best outcomes.

Traditional autorouters treat routing as a geometry problem. They can connect pins, but they don’t understand placement intent, manufacturability, or what a reasonable PCB layout should look. The result is often tangled routing, excessive vias, and significant cleanup work.

Flux’s AI Auto Layout takes a different approach. It’s a reinforcement learning model trained on professionally routed boards, allowing it to make routing decisions that resemble a thoughtful human first pass. It’s not designed to replace engineering judgment, but to handle bulk routing efficiently when paired with proper setup.

In this walkthrough, we cover:
What AI Auto Layout is and where it works best
The 80/20 workflow that consistently produces good results
What’s new in the Winter Update, including faster convergence and improved routing intelligence
How to prepare your board using stackups, power planes, rulesets, zones, and net priorities
How the routing process iterates and converges, and when to step in manually

AI Auto Layout works best on well-prepared two, four, and six layer boards, and is designed to remove repetitive routing work while keeping you in control of critical decisions.
