AI Auto-Layout Just Got Smarter

This update is a set of pragmatic steps toward our vision of AutoâLayout as your trusted routing assistant. Here's what's improved:
AutoâLayout still works best when guided by thoughtful placement, clear net names, and rulesetsâbut now itâs a more predictable, collaborative partner in your design process.
Classify your nets into seven priority bucketsâHighâŻSpeed, Analog, Power, MediumâŻSpeed, LowâŻSpeed, Uncertain, and Groundâand AutoâLayout will route them in that exact order. Flux will infer the Net Type of each net in your design, but you can check and change the inference by selecting a net and altering the Net Type property.
Highâspeed nets go first.
Analog nets get their own quiet lanes.
Power nets find robust copper paths.
This helps ensure your most sensitive signals arenât forced into awkward detours, delivering a draft layout that mirrors your own routing instincts.
Previous versions of Flux AutoâLayout often scrunched traces up against neighboring pads or nets to minimize length. Weâve softened that bias so traces now favor open board areasâeven if they grow a few mils longer.
Think of it as trading a few extra mils for a huge win in clarity and yield.
Earlier, AutoâLayout could inadvertently slice through copper poursâespecially smaller ones. Now, any polygon covering less than 10% of the board area is automatically protected from wires and vias unless you explicitly disable that rule.
AutoâLayout shines when you guide it. Hereâs a quick workflow that scales from beginners to power users:
Either way, AutoâLayout becomes a force multiplierânot a replacement for your expertise.
This Summer Update is a milestone on our roadmap. In the coming months, expect deeper AI understanding of complex topologies, tighter integration with constraint management, and collaborative features that let teams iterate on one layout in real time.
Your feedback is the compass that guides us. Try the Summer Update todayâlog in, hit âAutoâLayoutâ, and tell us where it shined or stumbled via inâapp feedback. Together, letâs make routing the easiest part of hardware design.
Explains how RC low-pass filters attenuate high-frequency signals using a resistor and capacitor, with the cutoff frequency formula, component selection trade-offs, and PCB layout best practices.
Covers how reflow ovens solder SMT components through preheat, soak, reflow, and cooling stages, with common defects and how PCB layout decisions impact manufacturing yield.
Gerber files are the universal 2D vector format that bridges PCB design and fabrication. This guide covers what each layer file contains, how to export and verify a complete manufacturing package, and the common mistakes that cause production delays.
A pi filter is a three-element passive CLC network that provides stronger ripple and EMI suppression than a single capacitor. This guide covers topology selection, component derating, resonance damping, and PCB layout best practices.
Tantalum capacitors offer high capacitance density in a tiny footprint but demand strict polarity and voltage derating. This guide explains how they compare to ceramics and aluminum electrolytics, common failure risks, and how to select and place them safely.
PCBA turns a bare PCB into a functional circuit by mounting and soldering components. This guide breaks down the assembly workflow, SMT vs through-hole methods, required manufacturing files, and common defects to avoid.
ERC checks schematic-level electrical issues while DRC checks PCB layout rules -- engineers run ERC before layout and DRC during or after routing.
The complete hardware design workflow covers requirements, schematic capture, PCB layout, validation, prototyping, and manufacturing.
