JTAG Technologies has added to its JTAGLive family of boundary-scan powered design and repair debug tools for PCBs.

This extension to the free-of-charge Buzz tool adds a ‘seek and discover’ capability, which effectively learns the network of nodes for a specified net connection.
 
As well as the new Buzz-plus option, the debug tools include additional extended modules ‘Clip’, which allows the engineer to create more customised logic cluster test patterns, and ‘Script’, a powerful command and control structure to manipulate and sense cluster I/Os utilising the popular Python language.

Script is suitable for functional-style, device-oriented tests such as testing mixed signal parts, operations that require user intervention, and looping test patterns to set up device registers.

99 free copies of Buzz-plus are available to existing Buzz users.

The JTAGLive debug tool is notable because it uses BSDL models of the compliant parts (usually freely available from IC vendors) to give the user access to all of the I/O pins for driving and sensing.

The user can define up to two boundary-scan chains and can quickly verify chain integrity through hardware adapters from Xilinx, Altera, JTAG Technologies and the dedicated JTAGLive controller/interface.
