Debugging Auto-Routing in TSCircuit: Fabrication Notes & SVG Visualization

Implementing Fabrication Note Components and Analyzing I-Jump A* Algorithm Behavior

In this deep dive into TSCircuit development, Seve tackles several intricate issues related to the auto-routing algorithm and component implementation. The video covers:

  1. Fixing a bug causing duplicate traces in the auto-router output

  2. Implementing fabrication note text and path components in TS-Circuit Core

  3. Creating tests for the new fabrication note components

  4. Exploring the auto-routing dataset viewer with debug mode enabled

  5. Analyzing the I-Jump A* algorithm's behavior in complex routing scenarios

  6. Identifying and reproducing a specific auto-routing issue where traces get too close to obstacles

  7. Discussing potential improvements to the goal-passing problem in the auto-router

Seve demonstrates advanced debugging techniques, including using the auto-routing dataset viewer to step through algorithm iterations and visualize routing decisions. He also touches on the challenges of developing interdependent modules in the TSCircuit ecosystem.

This video is particularly useful for contributors looking to understand the intricacies of the auto-routing algorithm, implement new components in TS-Circuit Core, and improve debugging workflows for complex PCB design scenarios.
