        Introducing AI Placement!
        AI Placement Demo

        AI-Powered Component Placement

        Let AI place your components intelligently. AI Placement analyzes your schematic and positions components for optimal routing, signal integrity, and board density.

        From Schematic to Layout in Seconds

        Skip the tedious manual placement. AI Placement generates a starting layout you can refine, saving hours of repetitive work on every new design.

        Works With Auto-Layout

        Pair AI Placement with Auto-Layout for a complete AI-driven PCB design flow — from component placement through trace routing, all with one click.
