1. A method of determining electric connections at a printed circuit board between boundary-scan compliant circuit terminals of at least one boundary-scan compliant device mounted on said printed circuit board and comprising a boundary-scan register of boundary-scan cells connected to said circuit terminals, said method using an electronic processing unit and comprising the steps of: a) retrieving, by said processing unit, boundary-scan properties of said at least one boundary-scan compliant device, said properties at least comprising a listing of boundary-scan cells operable as a driver and/or sensor; b) operating, by said processing unit, a boundary-scan cell connected to a circuit terminal as a driver and outputting data at said circuit terminal; c) operating, by said processing unit, at least one other boundary-scan cell connected to an other circuit terminal as a sensor for sensing data received at said other circuit terminal and latching said sensed data into said boundary-scan register; d) storing, by said processing unit, in a data storage device data from said boundary-scan register comprising said driver and sensor data; e) repeating, by said processing unit, steps b)-d) for a plurality of boundary-scan cells of said listing of boundary-scan cells; f) analyzing, by said processing unit, said stored driver and sensor data for determining electric connections between said circuit terminals on said printed circuit board; and g) presenting, by said processing unit, determined electric connections at said printed circuit board.
