XJTAG is a leading supplier of IEEE Std. 1149.1 compliant
boundary scan development tools. Its JTAG (Joint Test
Action Group) development system offers a highly
competitive solution for designers and developers of
electronic circuits. Utilising XJTAG allows the circuit
development and prototyping process to be shortened
significantly by facilitating early test development, early
design validation, fast development of functional tests and
test re-use across circuits that use the same devices.
XJTAG is based in Cambridge, UK, and is part of the
Cambridge Technology Group.
XJTAG was the first boundary scan solution to offer a
common platform for use by design and development
engineers, test engineers, contract manufacturers and field
test engineers, providing testing of not only JTAG-enabled
devices but non-JTAG devices as well.
Finding PCBA Shorts &
Other Faults: A Better Method
Two engineers discuss JTAG boundary scan:
What types of devices have boundary scan?
What is JTAG boundary scan and how does it work?
How to test a PCBA using boundary scan?
How boundary scan can extend test coverage to include
memories, clocks, ADCs, other serial peripherals, and
XJTAG 3.11 adds ARM® SWD support, user
libraries, and a clock generator to boundary scan
testing. These enhancements simplify the control of SWD
devices when JTAG can’t be used, increase flexibility,
and give you even greater convenience.
The XJTAG Development System is an established test suite
with a range of software and hardware products that enable
you to debug, test and program electronic circuits quickly
and easily. The system works with devices that conform to
the IEEE 1149.1 and 1149.6 boundary scan standards.
allows you to diagnose manufacturing problems on failing
boards. Combining the test capabilities of XJRunner and
XJAnalyser with additional diagnostic functionality,
XJInvestigator is the boundary scan tool to use at your
XJDeveloper is a
graphical application that allows you to quickly and easily
set up and run tests on your circuit. With XJDeveloper you
can reduce your time to market by reusing your test scripts
all the way through the product design process and then in
The simple drag-and-drop interface allows you to set up
your JTAG chain and categorise all of the non-JTAG devices
in your circuit easily. XJDeveloper includes built-in Layout
Viewer and DFT Analysis tools, along with Netlist
Explorer to view connectivity between devices.
XJDeveloper can also be used to program both JTAG
devices (e.g. CPLDs, FPGAs) and non-JTAG devices (e.g.
The XJAPI is a
simple-to-use DLL Application Program Interface (API),
designed to give you low-level access to the JTAG chain via
PXI hardware, allowing easy
integration with a wide range of other systems such as
development/evaluation boards, test systems...
The USB to JTAG hardware and software interface is composed
of a high-speed USB to JTAG hardware module (XJLink/XJLink2)
and the XJAPI, allowing you to access and control the JTAG
The PXI to JTAG hardware and software interface is composed
of a high speed PXI to JTAG hardware module and the XJAPI.
We can develop bespoke end user applications using the
XJAPI to meet your requirements.
