Many existing JTAG products simply apply the principles of "Bed of Nails"
testing: creating test vectors, writing them to a circuit and reading the
results back to determine a basic pass/fail of a circuit or JTAG device. With
XJTAG, the possibilities and capabilities of JTAG are extended far beyond
The XJTAG development system consists of a suite of software products and
XJLink (a USB-JTAG connector) that enable users to test and program electronic
circuits. It has been designed to unlock the potential of JTAG.
XJEase: The high-level JTAG language.
XJEase is device-centric, so you can
reuse the tests you write in different projects. It also allows you to use
loops, jumps and variables to adapt test sequences to the current state of the
Advanced proprietary connection test by making use of its
knowledge of the nature and interconnection of the devices in the circuit, XJTAG
is able to test a higher percentage of a circuit than many other JTAG solutions.
By monitoring the status of the devices in the circuit, XJInterconnect also
provides you with more information about the location and precise nature of any
faults that are found.
A graphical view of the JTAG chains on your board. Its
"Plug-and-Play" configuration gets you up and running quickly, allowing you to
set and read back pin values or to use SVF files to program devices on the
A simple-to-use DLL API interface to the hardware. We can craft the API
to meet whatever needs you have for the system, or you can buy a standard API.
