Software & Hardware Interface

The XJAPI is a simple-to-use DLL Application Program Interface (API), designed to give you low-level access to the JTAG chain via either the XJLink or the 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) and the XJAPI, allowing you to access and control the JTAG chain directly.

The PXI to JTAG hardware and software interface is composed of a high speed PXI to JTAG hardware module (PXI-01) and the XJAPI.

Key Benefits

Faster communication / download USB (480 Mbps), JTAG (60 Mbps peak)

USB to JTAG: Small, lightweight, portable hardware design — ideal for lab and field work

PXI to JTAG form factor also available: fully software compatible with the USB to JTAG version (3U/32 bit PXI/c PCI bus interface)

Self-contained licence allowing you to use the XJTAG system on multiple machines

Can be used with any pinout, ARM, Xilinx, Altera, etc.
