About the Pcb crossing optimizer

Pcb crossing optimizer is an open source PCB design by ashergarland, published on GitHub. It is a board, with 9 components from 8 distinct parts.

By type, the board carries 4 test points, 2 connectors, 2 resistors and 1 capacitor.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

Multi-layer crossing minimization for PCB connector pin assignment

The algorithms behind AI-native PCB design. This library powers the optimization pipeline in skidl-vscode — turning netlists into placement-optimized, crossing-free board layouts that any AI agent can produce.

When an AI agent uses the skidl-vscode MCP server to design a PCB, this library does the heavy math:

- Crossing analysis — Sugiyama-style barycenter sweep eliminates trace crossings by computing optimal pin orderings - Footprint planning — Pin-to-net assignment for custom footprints, respecting locks and anchor layers - Component placement — Hybrid force-directed + simulated annealing…
