JTAG Technologies: New Test Solutions
New hardware and software for boundary scan.
Eindhoven, The Netherlands — JTAG Technologies has introduced MAC-Panel Scout Mass Interconnect System — a new JTAG/boundary-scan hardware interface product compatible with the MAC-Panel Scout mass interconnect system. The JT 2147/DAK is a signal conditioning module that allows seamless connections from JTAG Technologies' PXI DataBlaster to the Scout's connection system.

Based on the highly successful QuadPod architecture from JTAG Technologies, the JT 2147/DAK has been specifically designed in the MAC Panel "Direct Access Kit" (DAK) form factor. In using the JT 2147/DAK, test system builders will be able to greatly simplify their wiring tasks and, at the same time, retain the excellent signal integrity assured by the QuadPod's active interface.

The JT2147/DAK has four independent JTAG Test Access Ports (TAPs) along with 16 user assigned Digital I/O channels. Each TAP can be programmed to operate through a range of voltage levels to suit various logic families.

Another new entry is 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 special "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 using a number of compatible JTAG interface options. AutoBuzz can then be set to gather a complete "connectivity map" of any board's 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.
