The JTAG to AXI Master IP core (hw_axi_1) allows the Vivado logic analyzer Tcl console
running on the control computer to interact with FPGA through the USB-to-JTAG port (U80)
on the KCU1250 board. The control computer periodically reads data samples via hw_axi_1
and creates an eye scan.
For more details refer to In-System Eye Scan of a PCI Express Link with Vivado IP Integrator
