JTAG Live is for checking PCBs for basic continuity and correct operation. Consists of three products: Buzz, Clip, and Script. Is compatible with JTAG programming cables from Altera and Xilinx, as well as with the two-port USB Explorer. Buzz provides the ability to check quickly (direct and indirect) connections between devices supporting boundary-scan; Clip offers ways to verify cluster logic using vector-based cluster tests, and Script enables users to adopt a functional, device-oriented test approach to take control of a design through on-board JTAG/boundary-scan compliant devices.
