Quilter

What it does

Quilter is physics-driven AI that automates PCB placement and routing. You prepare the design in your ECAD tool, upload it, and Quilter handles placement and routing. It uses reinforcement learning to explore thousands of generated candidate boards, and it shows every physics check it ran.

Quilter is built for hardware teams that want PCB layouts faster than manual work allows. You prepare the design in your ECAD tool, upload it, and Quilter handles placement and routing. You then review the output, make adjustments, and resubmit. The site says most boards go through 2 to 5 cycles before the engineer is satisfied, and that Quilter shows every physics check it ran so you stay in control. One example on the homepage says layout work quoted at 428 hours took 38.5 hours of human cleanup with Quilter. Pricing is pay per project, not per seat, and the cost of each board is based on the number of unrouted pins at upload. The homepage lists current capabilities: 100 to 1,000 components per board, around 2,000 to 5,000 pins for best performance, pin density under 20%, and through-hole vias, with blind and buried vias in development. A careful user should check which ECAD formats are supported and whether the output fits their fabrication requirements.
