The JTAG Live product family is all about helping you solve your hardware debug problems quickly and painlessly, the tool to have on your side when you need to locate faults on your prototype. JTAG Live's graphical screen shows you the pin-level details of the boundary-scan ICs on your board. There's no need for a netlist. Just drag-and-drop the pins of interest into the continuity  pane , hit the Measure button, and instantly see whether you've got continuity. If the sense pin is toggling, you'll see that, too. You can easily extend the measurement capability to multiple drive pins, or multiple sense pins, or both. And between multiple boards, too!

 JTAG Live gives you a choice of connection methods to interface your PC to the target board-use industry standard USB programming cables from Altera, or Xilinx. Or hook up the JT 3705 / USB controller from JTAG Technologies.

You can download the basic version of JTAG Live for free.  

When you want to go beyond debugging to create and run board-level tests JTAG Live grows with you. Using JTAG Live Clip and Script, you can develop tests and save them for future use, either at the bench or in production. The Clip add-on is geared to creating and running vector-based tests. Script is ideal for approaching the test functionally using the PythonT high-level language to test the board by means of boundary-scan resources.
With Buzz , you can easily define up to two boundary-scan chains and quickly verify chain integrity. Once the chains have been checked, Buzz provides a sample of the I/Os.

The watch window in Buzz shows you the current logic state of any specified boundary-scan pin on your board. Buzz also gives you a very handy continuity check to see if two pins on your prototype board are connected, essentially the familiar DMM's buzz measurement, but without probes. Within Buzz's Measure window, you select the drive pin, set it high or low, and read the resulting value on the sense pin.

Check for the presence of a pull-up or pull-down by setting the driver to Hi-Z. And, going well beyond the functionality of a DMM, Buzz shows multi-pin nets just as easily. Drive from one pin to many to check for correct fan-out connectivity or from multiple pins to one or more sense pins, thereby creating a simple cluster test.

AutoBuzz is a totally unique new tool that effectively learns a connectivity signature of all boundary-scan parts within a design from only the BSDL models of those parts. With its seek and discover mode AutoBuzz automatically gathers the circuit data of a known good board and then performs a full connectivity compare against the faulty circuit.

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.

Since the user requires no boundary-scan technical knowledge and with only a basic scan chain input needed, AutoBuzz is the perfect tool for repair and rework technicians, especially when design data is missing or incomplete.

CoreCommander takes control of key 'processor core (e.g. ARM, PPC, X-scale, Cortex etc.) functions using the built-in emulation/debug functions found in today's RISC and DSP cores. It has been developed to speed-up board testing and debug by enabling kernel-centric testing.

CoreCommander offers two modes of operation:

•  Interactive - offering direct control of the core or;
•  Python embedded - where controls can be scripted into a complete program.

JTAG Live CoreCommander:

Overcomes deficiencies in boundary-scan registers

•  Works with devices not compliant to IEEE std 1149.x
•  Most popular processor cores supported (ARM PPC etc..)
•  Code compatible with Python for test scripting
•  Low-cost compared to other solutions
Please note that CoreCommander modules are priced per core .

Script takes your testing to a new level, harnessing the power of the PythonT programming language. With the Script upgrade, you'll be able to generate test scripts even for complex sequential clusters, make analog measurements, and perform flash and SPROM programming.

The Script module provides a powerful command and control structure to manipulate and sense cluster I/Os. Script is ideal when adopting a functional, device-oriented test approach for such applications as testing mixed signal parts, operations that require user intervention, and looping test patterns to set up device registers.

With Script, you'll use the Python TM open-source programming language to verify operation of non-boundary-scan clusters. By means of high-level routines that can be embedded in a Python program, Script drives and senses values on pins or groups of pins. The Python editor facilitates preparation of the sequences to perform tests and collect results.

Creating test modules in Script promotes device orientated testing and hence re-use of test code. Using Python open source means that thousands of auxiliary routines can be obtained from the established user community.
  BuzzPlus allows easier detection of bridging or short-circuit faults. With BuzzPlus you can find all the boundary-scan connections for two drivers simultaneously. If connections are missing, or if shorts occur between these two nets, those can easily be seen.

While Buzz allows the user to sample activity on boundary-scan pins and test continuity of nets across a circuit board, BuzzPlus extends the capability with a unique 'seek and discover' mode; that effectively learns the network of nodes for a specified net connection.

If you are an existing user of Buzz you can now apply for BuzzPlus for free ! Simply provide us with your full contact details, your existing Buzz licence and a short text (approx. 50 words) telling us how Buzz has helped you and how you evaluate the application*. The first 99 users will receive a free upgrade to BuzzPlus.

* By accepting your free BuzzPlus licence you agree to allow JTAG Technologies to quote your statements regarding your use of JTAG Live applications for JTAG Technologies' promotional purposes.


JTAG Live's Clip module allows you to create more complex vector-based cluster test sequences. Each vector in a sequence contains a set of drive values for device inputs and the corresponding sensed values on the device outputs. Clip's logic analyzer-like waveform display shows you the I/O vectors, and by storing the sequence for a known-good board, you can actually create a test for boards of the same type, which is extremely useful when you need to debug multiple prototypes.

Using Clip you can set-up vector sets in Hex, Binary and Decimal formats for many types of debug applications such as Flash ID-code testing or testing I 2 C and SPI bus protocol parts. If you can access the critical signals of your device with boundary-scan enabled pins then you can most likely test it with Clip. Vector sets can be up to unlimited patterns long and with no limit to the number of pins used. Built in vector generation modes include, Walk 1, Walk 0 and Binary count.
