Go From Schematic to Board on Your Desk in a Fraction of the Time

Works With Your Existing Workflow

Upload Altium, Cadence, Siemens, or KiCAD projects directly. Define the board outline, pre-place connectors, determine the floorplan. You control the constraints.

Physics-Aware Design

Quilter identifies bypass capacitors, impedance-controlled nets, differential pairs, and other critical considerations for your review. You see exactly what Quilter will and won’t account for up front.

Iterate More

Try multiple stack-ups, multiple manufacturers, multiple form factors. All in parallel, in hours instead of weeks. Quilter makes layout fast and abundant.

Transparent Design Review

Quilter evaluates each layout against the full list of physical constraints provided. You get clear feedback on which design aspects are truly “done” and which need further review and improvement. 

Seamless Board Handoff

Quilter returns files in the same format as you submitted. Run DRC, polish, generate fab files - all in the CAD tools you already use.

Honest About What We Do Well

Engineers probe for limits. We'd rather you hear them from us. Quilter has a goldilocks zone today, and it's expanding with every release.

Dimension Current Capabilities Status
Components 100 to 1,000 per board
Pins to route No inherent limit, but the current best performance is around 2000-5000
Pin density Under 20% (footprint area over board area)
Via types Through-hole only. Blind/buried are in development
BGA fanouts Automated fanout generation
Length matching Coming soon
RF Pre-route RF nets, Quilter handles the rest
Live Beta In development
