Service
Nobody wants to wait a long time for the repair of a product. JTAG/boundary-scan can help to shorten repair times even if no, or only limited, design data is available and can be used to re-program parts for system upgrades.
JTAG Live™ Buzz provides an easy solution for continuity test and 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 testing 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.
The JTAG Live Controller is USB connected and powered and features a single test access port in JTAG Technologies standard 10-way IDC pin-out. The JTAG Live controller is a smart, low-cost and easy-to-use USB JTAG/Boundary-scan interface.
It offers a maximum programmable TCK speed of 6 MHz and also features programmable output voltages and input thresholds.
The JTAG Live controller is compatible for use with both JTAGLive software and ProVision.
The JT 3705/USB Explorer is a low-cost two port USB powered boundary-scan controller interface specifically suited for low volume testing and in-system programming of (C)PLDs. Explorer supports two fully-compliant boundary-scan test access ports (TAPs) which can be synchronized for test purposes.
Features include 6MHz maximum TCK frequency and adjustable input and output thresholds.
The JT 3705/USB is support by ProVison‘s custom combined instrument feature that allows multiple controllers to act as one.
The JT 5705 series offer a unique combination of JTAG TAP controller (tester) interfaces plus digital and analog I/O in compact desktop package.
Use the ‘mixed-signal’ features to measure power supplies, clock frequencies or test DACs and ADCs. Add your own capability through use of CoreCommander FPGA our generic bridge/translator system.
The JT 5705/USB version is a desktop model with 2 TAPs and 64 I/O making it ideal for hardware validation or small-scale production test. Maximum TCK speed is 15 MHz and all voltages are fully programmable. The JT5705/FXT is the ‘fixture’ version supplied as a pcb assembly only with optional ‘break-out’ boards available depending on your application.
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.

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 which is then saved as a reference. Compare mode is then used to check the known good reference against the faulty circuit.

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.

Script uses the open-source Python language to provide a powerful command and control structure to drive and sense boundary-scan I/O pins for ‘cluster’ testing.
Using Script, you’ll create Python code to verify operation of non-boundary-scan logic. LEDS and mixed signal devices. 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 defined as variables. The built-in JTAGLive Python editor simplifies 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 additional libraries can be obtained from the established user community.

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.

JTAG Live Studio is your complete JTAG/boundary-scan solution for testing, debugging and programming your designs. Based on the JTAG Live platform that now includes an automated scan path builder, Studio includes JTAG Live Buzz, BuzzPlus, AutoBuzz, Clip, Script, JAM, STAPL and SVF players PLUS a JTAG Live controller.
With the latest version of AutoBuzz, interconnections can be tested using a comparison with a known good board or by learning boundary-scan pin connections from a CAD-derived netlist. Create reusable cluster tests and flash programming actions in Python using Script. Include IC-level tests by adding low-cost CoreCommander options that can control IC cores and/or link to FPGA gate array fabric.
