XJTAG Limited

PCB Test & Programming made easy with XJTAG
Unlock your board’s potential for test, debugging and device programming with XJTAG Boundary Scan.
XJTAG uses the JTAG (IEEE 1149.x) already embedded in FPGAs, CPLDs and most CPUs today.

XJTAG works with the JTAG / IEEE 1149.X boundary scan test standard built into FPGAs, CPLDs and most CPUs.

Introduction to JTAG
JTAG is a technology which is in its third decade as an industry standard. However, its potential as a testing and programming tool is only just beginning to be fully realised.

Applications
Connection testing and In System Programming (ISP) are the two applications most commonly associated with JTAG. However the technology has far more to offer.

Non-JTAG-compliant sections of a circuit can be tested by using the interconnecting nets between the devices in the JTAG chain and other devices in the circuit.

XJTAG has been designed to unlock the potential of JTAG, with its development system of software products and JTAG controller hardware (available with a range of connectivity options).
