Physical Design Problems

Build a design, hunt its bugs, or repair what fails. Every answer runs on a real simulator.

Build starts from a specification: make it work, then make it small or fast. Bug Hunt asks for the checker or the test that catches broken designs. Repair hands you a failure: find the cause, then fix the design.
