Quilter is enterprise-grade, physics-driven AI that automates printed-circuit-board layout design. Engineers upload a schematic and board outline, and Quilter handles component placement and routing end-to-end, turning weeks of manual work into hours while keeping engineers in full control. Unlike legacy auto-routers or LLM-based tools, Quilter reasons from the physics of the board to produce complete layouts in your native ECAD format, with physics checks applied as each candidate is built. Quilter supports Altium, KiCad, Cadence, and Xpedition files, and is available as a cloud platform or on-premises deployment.
