Automatic test generation and fault diagnosis of boundary scan circuits

The author describes an automatic method, and its software implementation, for testing and diagnosing printed circuit boards (PCBs) in a boundary scan (BS) environment. Test patterns for the BS chain and the board's interconnect are generated automatically based on a description of the components forming the board and their interconnections. The diagnosis of faults is also performed automatically based on the measured circuit responses to the tests applied.<
