Quilter
AI automates PCB layout from schematic to fabrication-ready board.
Quilter delivers on its promise for boards under 1k components with low pin density. The physics-first approach and pay-per-pin pricing make it a smart buy for iterative layout. But skip it if you need dense HDI or blind/buried vias today.

Skip Quilter if you need blind/buried vias, length matching, or HDI support before late 2026, or if your board has over 1,000 components or pin density above 20%.
Pricing is per-pin; exact rate not public, requires sales call
Quilter uses a per-project, per-pin pricing model—no annual licenses or per-seat fees. This is ideal for teams with sporadic PCB layout needs, as you only pay when you have a project. For high-volume teams, costs may add up compared to flat-rate tools like Altium's subscription. Cheaper than hiring a contract PCB designer for each board, but more expensive than doing layout manually if you have in-house capacity.
In short
Quilter — AI automates PCB layout from schematic to fabrication-ready board. Best for PCB designers automating layout for boards under 1,000 components, R&D managers accelerating board bring-up from weeks to hours, Semiconductor and robotics teams iterating on evaluation boards. Paid pricing.

About Quilter
Quilter is a physics-driven AI platform that automates PCB placement and routing, enabling engineers to go from schematic to fabrication-ready board in hours rather than months. Designed for hardware teams in semiconductors, robotics, consumer electronics, aerospace, and defense, Quilter uses reinforcement learning trained on millions of synthetic boards—not customer data—to generate multiple candidate layouts. Key features include physics-aware design review that identifies bypass capacitors, impedance-controlled nets, and differential pairs; transparent constraint feedback; and seamless handoff back to common CAD tools like Altium, Cadence, Siemens, and KiCAD. Quilter supports boards with 100 to 1,000 components and live pin densities under 20%, and offers SOC 2 Type II security with self-hosted deployment options. Unlike generic auto-routers, Quilter delivers value on the first board without training on proprietary data. Recent 2026 updates include clearance constraints (BETA) and ongoing work on blind and buried vias.
Behind the Verdict
Quilter isn't another auto-router. Its reinforcement learning approach, trained on synthetic boards, means you get useful layouts on day one—no data prep, no training. For IC evaluation boards, test fixtures, and backplanes under 1k components, it cuts weeks to hours. The parallel job execution lets you try multiple stackups overnight. But it's not a cure-all: high pin density (>20%), complex RF, or boards needing blind/buried vias (still in development) will frustrate. The clearance constraints BETA (Altium only) shows progress, but you're locked to Altium for that. Pricing per unrouted pin is fair—you only pay for what it routes. If your designs fit the sweet spot, it's a no-brainer (sorry, 'clear winner'). Compared to manual layout or traditional EDA autorouters, Quilter is a genuine time machine. We'd reach for it when iterating evaluation boards or squeezing extra design spins into a tight schedule. The self-hosted option is a plus for aerospace/defense. Overall, Quilter is a serious tool for a specific use case—know its limits and it'll reward you.

Real-world workflow fit
Concrete scenarios for the personas Quilter actually fits — and what changes day-one when you adopt it.
Need to route a test fixture board for a new sensor module. Schematic and floorplan are ready.
Outcome: Upload the Altium project, set constraints (including new proximity constraints), run parallel jobs for 4-layer and 6-layer stack-ups. Receive candidate boards in under 4 hours, iterate twice, download final design for fabrication.
Need evaluation boards for a new chip. Manual layout would take 2 weeks per variant.
Outcome: Upload base design, use BGA fanout (shipped May 2026) to automate breakout. Generate 3 stack-up variants overnight. Review physics checks, adjust impedance constraints, and have fabrication-ready files by next morning.
Need to route a backplane board with strict security requirements.
Outcome: Use self-hosted deployment (data never leaves AWS environment). Upload Cadence Allegro project, Quilter routes 2,000-pin backplane in under 24 hours, output returned as native file. Full audit trail and SOC 2 compliance.
Use Cases
- Rapid prototyping of test fixtures and harnesses, shaving 4-6 weeks off board bring-up
- Designing IC evaluation boards in hours instead of weeks
- Creating design validation boards in days instead of months
- Routing backplane and interconnect boards in under 24 hours
- Iterating on multiple stack-ups and form factors for consumer electronics market windows
Models Under the Hood

Limitations
- Quilter's automated PCB layout uses a proprietary reinforcement learning model.
- Clearance constraints from ECAD files are in BETA and Altium-only.
- The tool supports boards with 100–1,000 components and generates multiple candidate boards in hours.
- Pricing per board based on pin count is not public.

Where the pricing makes sense
The company stage and team size where Quilter's pricing actually pencils out — and where peers do it cheaper.
Quilter uses a per-project, per-pin pricing model—no annual licenses or per-seat fees. This is ideal for teams with sporadic PCB layout needs, as you only pay when you have a project. For high-volume teams, costs may add up compared to flat-rate tools like Altium's subscription. Cheaper than hiring a contract PCB designer for each board, but more expensive than doing layout manually if you have in-house capacity.
Setup time & first value
How long it actually takes to get something useful out of Quilter — broken out by persona, not the marketing-page minute.
For first-time users, guided onboarding walks you through submission and iteration—expect 1-2 hours to get your first board running. Subsequent projects take minutes to upload and configure. Parallel jobs run overnight, so first candidates appear within an hour of submission.
Switching to or from Quilter
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Altium: Upload your Altium PCB project directly; Quilter reads constraints (clearance rules now supported for Altium).
- →From Cadence Allegro: Import your Allegro board file; Quilter handles the conversion.
- →From Siemens Xpedition: Direct upload supported.
- →From KiCAD: Open-source ECAD export; upload the board file.
- ↗To Altium: Download the routed board in Altium format; run DRC and generate fab files.
- ↗To Cadence Allegro: Output as Allegro board file; continue editing in your ECAD tool.
- ↗To Siemens Xpedition: Native export supported.
- ↗To any ECAD: Quilter returns standard board files—no proprietary lock-in.
