ABSTRACT:
A device for detecting the existence and location of failures on circuit boards is disclosed. The device is specially adapted for use with boards having a number of serially connected digital loops. Digital circuitry is provided which simultaneously compares a number of checkpoints on the faulty board with corresponding points on a known good board, and the first point to fail is isolated. Inhibit circuitry prevents failure indications at checkpoints if those failures occur subsequent to the first failure.
