Method, arrangement and computer program product for debugging a printed circuit board

A debugging arrangement for debugging a printed circuit board, and/or at least one test-pattern for such printed circuit board, said printed circuit board comprising a plurality of devices mounted on said printed circuit board having circuit terminals for interconnecting said devices, said devices comprising at least one boundary-scan compliant device having boundary-scan compliant circuit terminals and comprising a boundary-scan register of boundary-scan cells of said boundary-scan compliant circuit terminals, said debugging arrangement comprising an electronic processing unit configured for:

• retrieving 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;
• retrieving connectivity properties of said plurality of devices mounted on said printed circuit board, said connectivity properties at least comprising a listing of interconnects between said circuit terminals of said devices;
• displaying a circuit graph of at least a part of said devices mounted on said printed circuit board, said circuit graph comprising at least one device of said plurality of devices mounted on said printed circuit board and a least one further device from said plurality of devices which comprises a circuit terminal interconnected to a circuit terminal of said device for visualizing at least said device, said further device and interconnects between said devices for debugging said printed circuit board;
• wherein said device is determined by receiving, by a processing unit, a selection from one of the group of:
• said printed circuit board, said devices mounted on said printed circuit board, and a circuit terminal of one of said devices mounted on said printed circuit board.
