The MGTs on the Xilinx Kintex-7 provide a debugging capability called Eye Scan. The Eye Scan API VIs are located on the LabVIEW VI palette at FPGA Interface » Software-Designed Instruments » NI High-Speed Serial » NI Eye Scan.

You must connect the GTX2_CHANNEL register(s) on the FPGA to use Eye Scan. Refer to the Wiring the Instruction Targets section for information about connecting the GTX2_CHANNEL register. Refer to the Aurora sample project to learn how to use the Eye Scan API in an application.

National Instruments offers two versions of Eye Scan: Rectangular Eye Scan and N Point Eye Scan. Use Rectangular Eye Scan to obtain a traditional eye that sweeps the unit interval and nominal voltage. Use N Point Eye Scan to measure the Bit Error Ratio at arbitrary unit interval and nominal voltage offsets. For information about the Rectangular Eye Scan VIs and N Point Eye Scan VIs, refer to the NI  High-Speed Serial Instruments Help.
