Patent ID: 8601333

Claim:
A method of testing connections on a printed circuit board between boundary-scan compliant circuit terminals of at least one boundary-scan compliant device mounted at said printed circuit board and comprising a boundary-scan register of boundary-scan cells of said boundary-scan compliant circuit terminals, said method using an electronic processing unit and comprising the steps of: retrieving, by said processing unit, boundary-scan properties of said at least one boundary-scan compliant device, said boundary-scan properties at least comprising a listing of boundary-scan compliant circuit terminals of said at least one boundary-scan compliant device; displaying, by said processing unit, a list comprising said boundary-scan compliant circuit terminals of said at least one boundary-scan compliant device; receiving, by said processing unit, a selection of at least a first and a second boundary-scan compliant circuit terminal of said list; operating, by said processing unit, a boundary-scan cell of said first boundary-scan compliant circuit terminal as a driver and outputting by said driver data at said first boundary-scan compliant circuit terminal supplied from a boundary-scan register comprising said boundary-scan cell operating as said driver; operating, by said processing unit, a boundary-scan cell of said second boundary-scan compliant circuit terminal as a sensor for sensing data received at said second boundary-scan compliant circuit terminal and latching data sensed by said sensor into a boundary-scan register comprising said boundary-scan cell operating as said sensor; analyzing, by said processing unit, said boundary-scan register driver and sensor data for a connection between said first and said second boundary-scan compliant circuit terminals, and presenting, by said processing unit, a result of said analyzing of said driver and sensor data.
