- The coach traces the drivers behind a selected wire and highlights the cause; the simulator models 0, 1, Z, and error states.
Field notes
The coach is framed as a trace, not just an answer: it follows a selected wire or pin through its drivers, highlights the cause, and presents a four-step explanation from “Where to look” to “Conclusion.” The simulator models 0, 1, Z, and E on wires and buses up to 32 bits; its K-map workflow uses Quine–McCluskey minimization before gate synthesis. The page identifies the project as GPL-3.0-or-later software and links to GitHub and a changelog.
