The JTAG-to-AXI Master debug core is a customizable core that can generate the AXI transactions and drive the AXI signals internal to an FPGA at runtime. The core supports all memory-mapped AXI and AXI-Lite interfaces and can support 32 or 64-bit wide data interfaces.

The JTAG-to-AXI Master (JTAG-AXI) cores you add to your design appear in the Hardware window under the target device. If you do not see the JTAG-AXI cores appear, right-click the device and select Refresh Hardware. This re-scans the FPGA and refreshes the Hardware window.

Note: If you still do not see the ILA core after programming and/or refreshing the FPGA device, ensure the device was programmed with the appropriate .bit file and the implemented design contains an ILA core.

Click to select the JTAG-AXI core (called hw_axi_1 in the following figure) to see its properties in the AXI Core Properties window.
