## Overview
Quilter is a physics-driven AI tool that automates PCB (printed circuit board) placement and routing, enabling engineers to generate fabrication-ready board designs in hours rather than weeks or months. The tool works with existing EDA workflows by accepting projects from Altium, Cadence, Siemens, and KiCAD formats, allowing users to define constraints and maintain design control throughout the process. What distinguishes Quilter is its physics-first approach: the AI learned layout by simulating millions of synthetic boards against the laws of physics rather than training on customer data, meaning designs are validated for functionality from the start. The tool targets regulated industries and supports various deployment models including self-hosted options with encrypted data handling. One notable limitation is that Quilter currently works best on boards with 100-1,000 components and performs optimally at under 20% pin density, though the company acknowledges this capability zone is expanding with each release.
## Key Features
- Physics-first AI validation of all design candidates
- Works with Altium, Cadence, Siemens, and KiCAD projects
- Support for 100-1,000 components per board
- Handles through-hole vias and supports routing up to 2,000-5,000 pins optimally
- No training on user data; learns from synthetic physics simulations
- Data encryption at rest and in transit (TLS 1.3, AES-256)
- SOC 2 Type II compliance for regulated industries
- Self-hosted deployment option available
- Enterprise-grade support for mission-critical environments
- Transparent design review process
- Multiple design candidate generation

## Use Cases
- Test fixtures and harnesses: Save 4-6 weeks on board bring-up
- IC evaluation boards: Convert weeks-long layout cycles to hours with fabrication-ready designs
- Design validation boards: Reduce validation cycles from months to days
- Backplane and interconnect boards: Complete designs in under 24 hours instead of 30+ days
- Rapid prototyping in semiconductors, robotics, consumer electronics, and aerospace & defense industries

## Who It Is For
- PCB designers and layout engineers
- R&D managers seeking faster board bring-up
- Electrical engineers working on hardware design
- Hardware teams in semiconductors, robotics, consumer electronics, and aerospace & defense
- Organizations in regulated industries requiring compliance and data security
- Design teams working with existing Altium, Cadence, or Siemens workflows

## Pros
- Physics-first training approach ensures designs are functional from the start without requiring customer data cleanup
- Massive time savings: transforms months-long PCB layout processes into hours, enabling rapid iteration and competitive advantage
- Enterprise-ready security with SOC 2 Type II compliance, self-hosted deployment options, and end-to-end encryption
- Seamless integration with existing industry-standard EDA tools (Altium, Cadence, Siemens, KiCAD)

## Cons
- Limited to boards with 100-1,000 components; performance degrades outside this range
- Optimal performance at under 20% pin density limits applicability for high-density designs
- Some advanced features remain in development (blind & buried vias, length matching, RF pre-routing) or coming soon
