Quilter

Quilter is a web-based AI platform for automated PCB layout built for hardware engineers and PCB design teams who need faster schematic-to-board iteration.

Key capabilities include:

• Automated placement and routing from uploaded schematics and user-defined constraints, including controlled impedance, length matching, differential pairs, pair coupling, return paths, power pours, and EMI/EMC considerations.
• Multiple candidate boards in parallel, letting teams explore different stack-ups, manufacturers, and form factors in hours.
• Native CAD integration that reads and writes project files for Altium, Cadence, Siemens, and KiCad, enabling upload and download without format conversions.
• Validation and review tooling, including physics-aware checks, DFM considerations, and detection of critical elements such as bypass capacitors and impedance-controlled nets.

Pricing: Freemium, with a fully autonomous free tier offering unlimited iterations, plus paid options.

Notable for combining physics-driven validation with native-file handoff, so teams can run DRC, polish layouts, and generate fabrication outputs in their existing CAD workflow. Quilter has also demonstrated rapid end-to-end layout by completing a functional computer design in under a week.
