XJAnalyser

Overview

Note that it is not currently possible to set up a new project using XJLink-PF series controllers from within XJAnalyser. However, XJAnalyser can open projects (created by XJDeveloper) which support any of XJTAG's JTAG controllers, and can run these. Future versions of XJTAG will allow direct project creation using XJLink-PF series controllers.

XJAnalyser provides a graphical view of the JTAG chain present on the target hardware. It allows you to view and/or control, on a pin-by-pin basis, pin state (driven high/low as an output or held tristate as an input) and the current logic value of the pin.

XJAnalyser can either perform continuous write-read JTAG scans, giving instant feedback on signal changes, or it can iterate single scans under user control, allowing manual changes between each scan.

These abilities provide XJAnalyser with a variety of distinct functions:

• Verifying the connection of the JTAG chain
• Checking JTAG chain integrity and debugging problems
• Controlling pin states in a circuit
• Monitoring signal information from a circuit
• Programming JTAG devices using SVF or STAPL/JAM files
