When the tools of a craft reach their limits, the craftsman must sometimes forge new ones. A developer named Brian, confronted with a PCB so densely connected that conventional autorouters could not complete the task, built OrthoRoute — a GPU-accelerated plugin for KiCad that borrows its core algorithm from the world of FPGAs. In doing so, he demonstrated that the boundary between "impossible" and "merely unsolved" is often a matter of finding the right analogy from another domain.
