JTAG Chain Debugger

You access this tool by clicking Tools > JTAG Chain Debugger. The JTAG Chain Debugger tool is available only when the Programmer window is open and you have a device connected through the JTAG chain.

Allows you to run the JTAG Chain Debugger from within the Programmer in the Quartus® Prime software. You can scan a JTAG chain to ensure that devices in the chain are properly connected or you can run a saved JTAG Chain Debugger session log file.

The JTAG Chain Debugger also prevents you from inadvertently overwriting the chain description in the Programmer unless you first confirm that you want to do so.
