Abstract :
A signature analyser detects and displays the unique digital signatures associated with the data nodes in a circuit under text. By comparing these actual signatures with the correct ones, faulty nodes can be detected. The technical details of a practical signature analyser for use in production are presented and its application to the testing of complex printed circuit boards incorporating l.s.i. devices, such as memories and microprocessors, is described.
