Eindhoven, the Netherlands, September 27th, The makers of JTAG Live Buzz and Buzz-plus are proud to announce AutoBuzz, the most exciting addition yet to their no-netlist-required range of JTAG/boundary-scan test and debug tools. AutoBuzz is an amazing tool that uses a unique seek and discover feature to scan completely a compliant design and then perform comparative tests using JTAG/boundary-scan. With only JTAG scan-chain information plus BSDL models of the JTAG/IEEE std 1149.1 compliant parts (available from manufacturers web-sites), users of AutoBuzz will be able to connect to their designs via a number of compatible JTAG interface options. AutoBuzz can then be set to gather a complete connectivity map of any boards boundary-scan to boundary-scan pin connections (where these can be direct or via transparent devices such as series resistors). AutoBuzz supports just two simple operating modes: Learn and Compare. With AutoBuzz in Learn mode a known good sample PCB is initially scanned to establish a reference connectivity map. Suspected faulty boards can then be scanned by AutoBuzz in Compare mode, and a comparison is automatically made of their connectivity maps. Differences between the two maps are highlighted to indicate possible faults such as interconnect short-circuits, open-circuits or stuck-at faults.
