1.2.4. JTAG Chain Debugger Tool

The JTAG Chain Debugger tool allows you to test the JTAG chain integrity and detect intermittent failures of the JTAG chain. You access the tool by clicking Tools > JTAG Chain Debugger on the Intel® Quartus® Prime software.

In addition, the tool allows you to shift in JTAG instructions and data through the JTAG interface, and step through the test access port (TAP) controller state machine for debugging purposes.
