JTAG Live™ Buzz provides an easy solution for debugging boards too crowded for traditional probing with scopes or logic analysers - what's more it's totally free. Buzz is ideal for electronics engineers and technicians to use in checking printed circuit boards for basic continuity and correct operation. Buzz simply uses the built-in pin access provided in boundary-scan (IEEE Std 1149.1) compliant devices to perform pin to pin continuity tests (Buzz-outs) and can also sample pin activity on input pins.
Buzz 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. Watch mode allows the user to see if any given pin is stuck high, stuck low or is toggling.
Features:
- Up to 10 drive and sense pins
- Works without a netlist
- Support for multiple boundary-scan chains
- Scan chain infrastructure test
- Sample pin activity
- Pin-to-pin (p2p) continuity testing
- Multi-pin-to-multi-pin (np2np) continuity testing
- Multi-hardware support Explorer/USB, Altera, Xilinx
While Buzz allows the user to sample activity on boundary-scan pins and test continuity of nets across a circuit board, BuzzPlus extends its capability with a unique ‘seek and discover’ mode that effectively learns the network of nodes for a specified net connection.
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.

- Manual seek and discover mode (2 nodes)
- Unlimited sense pins
- Works without a netlist
- Support for multiple boundary-scan chains
- Scan chain infrastructure 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. By expanding on the seek and discover mode of BuzzPlus, AutoBuzz automatically gathers the circuit data of a known good board and then performs a full connectivity compare against the faulty circuit.
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 routines take 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. They have been developed to speed-up board testing and debug by enabling kernel-centric testing. CoreCommander offer two modes of operation:
- Interactive - offering direct control of the core or;
- Python embedded - where controls can be scripted into a complete program.
Please note that CoreCommander modules are priced per core. While ordering specify the target core from following set.
CoreCommander routines can be used to boost test coverage in applications that have only a small amount or even no IEEE std 1149.1 (conventional boundary-scan) test access options. By taking hold directly of the target processor's core the user can write to or read from configuration registers and internal or external memory spaces.

Features:
- JTAG control of µprocessors, and DSPs via core debug access
- Create cluster tests and flash applications
- Overcomes deficiencies in boundary-scan registers
- Works with devices not compliant to IEEE std 1149.x
- Most popular processor cores supported (ARM PPC etc.)
- Simple to use interactive GUI to perform core writes/reads
- Functions include 'EnterDebug', 'ExitDebug', 'LoadMemory', 'SaveMemory', 'WritePC', 'ReadPC'
- Compatible with Python open-source scripting language
- Works in tandem with JTAG Live Script - boundary-scan routines.
Clip is the vector-based upgrade for creating and saving board-level tests. It features unlimited pattern depth and bit width. Clip's logic analyzer-like waveform display shows you what's happening with the signals on your board. Use Clip's "Compare On" and "Set Breakpoint" options for complete execution control.
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 I2C 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.

Script uses the open-source Python™ language to provide a powerful command and control structure to manipulate and sense cluster I/Os. With Script, you'll use the Python code 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.
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.
