Hands-on
Solve every exercise in the browser. No installs, no setup, no licenses. Open the editor, write the logic, run the tests.
Beginner to expert
Start with simple bit logic. Work up through timers, counters, and state machines — more advanced scenarios land as the catalog grows.
Real tests
Each exercise ships with test vectors. Pass them all to mark it done. Fail one and the runner tells you which scan and which signal disagreed.
