Compliance testing
Beginner
Official tests that prove a chip follows a standard, such as USB, so it works with everyone else’s devices.
Novice
Testing a product against a standard body’s official test suite, at authorized test labs or at events where companies test their products together. Passing can earn a listing and the right to use the standard’s logo.
Expert
Plan it at the spec stage: pick IP that has already passed, budget for test chips or boards, and add the test modes the standard requires (such as loopbacks) to the requirements.
