Quilter is physics-driven AI that handles PCB placement and routing end-to-end, like a dedicated junior PCB engineer on your team.
Upload your schematic and board outline. Quilter handles placement, routing, and validation against your constraints, then returns completed layout candidates in native file formats for Altium, Cadence Allegro and OrCAD, Siemens Xpedition, and KiCAD.

Watch the full walkthrough for everything you need to go from a set of ECAD files to a finished board layout.
Still have a question?
Quilter needs a complete schematic and a board outline from your ECAD tool (Altium, Cadence Allegro & OrCAD, Siemens Xpedition, or KiCAD). The board file should include the board outline, mounting holes, connectors, and any other mechanically critical components already placed. Anything inside the board outline is treated as locked. Anything outside is what Quilter will place for you.
For better outputs, include rooms or placement regions to guide the floor plan, set your stackup and DRC rules, and use net classes to flag power nets and differential pairs.
No. Quilter handles placement and routing on the boards it handles well, which frees your layout experts to focus on the designs that actually need their judgment. On the complex boards that define your products, layout engineers keep doing what they do best. Teams report clearing routine work faster, not shrinking headcount.
Cleanup typically takes a few hours on simpler boards and 30 to 40 hours on Quilter’s most complex production cases. For Project Speedrun, an 843-component, 5,141-pin Linux motherboard, cleanup totaled 38.5 human hours against the 428 hours quoted by professional layout services. Cleanup time drops sharply after the first few boards as your team builds fluency with Quilter’s outputs.
Cleanup typically includes finishing the few remaining unrouted nets in your ECAD tool, addressing any DRC violations Quilter flagged, running your own DFM checks, and applying your team’s aesthetic and organizational standards.
No. The enterprise version of Quilter does not use any customer data for training. The free version does parse your board to generate synthetic data for training, but it does not “learn” or “memorize” your design. Quilter learned layout by playing millions of synthetic boards against the laws of physics, the same way AlphaGo engines learn their games.
Quilter reasons from physics; auto-routers don’t. Auto-routers take placement as a given and play a connect-the-dots game on a 2D grid, drawing traces between pins with no understanding of what the signals are doing. Quilter reads your schematic to identify what matters electrically (differential pairs, DDR timing, bypass capacitors, switching converters, impedance-controlled nets), calculates the geometric rules each net needs for every stackup, and handles placement, stackup, and routing as one connected problem.
No. PCB layout is a physics and geometry problem, not a language problem. Quilter is trained to generate complete layouts that pass electrical and manufacturing checks. It does not hallucinate traces or invent routing from text patterns.
Altium, Cadence Allegro, Siemens Xpedition, and KiCAD. You start in your ECAD tool, submit to Quilter, and get back candidates in the same native file format. No SPECCTRA, ODB, or third-party converters.
Up to 10,000 pins, with the sweet spot at 2,000 to 5,000. There is no inherent pin limit. Quilter is best suited to low-voltage (under 48V) and low-current (under 10A) designs at low-to-medium pin density (below roughly 20% pin density). RF-dominant, high-voltage, and very high-density HDI designs are not a fit yet. Quilter is improving rapidly — check our documentation for the latest information on what Quilter handles well.
Yes. Quilter deploys into your own environment (AWS, GCP, Azure, or whatever else your team already uses). Same software, same outputs as the cloud version.
Pricing scales with unrouted pin count, so you buy capacity when you have a project and don’t pay when you don’t. That fits how layout already gets budgeted at most companies, whether you pay a contract layout house per board or allocate internal engineering hours per program. Iterations within a project are unlimited. Contact us for enterprise pricing on production programs.
Yes. Quilter offers a free version. The free version includes the same functionality as the paid product, but designs uploaded into the free version may be used to improve Quilter’s AI model. For commercial work that requires IP protection, dedicated cloud workspaces, or on-premise deployment, a paid pilot is the right starting point.
