Taxi Example Design for KCU105
Introduction
This example design targets the Xilinx KCU105 FPGA board.
The design places looped-back MACs on the BASE-T port and SFP+ cages, as well as a looped-back UART on on the USB UART connection.
- USB UART
- Looped-back UART
- RJ-45 Ethernet port with Marvell 88E1111 PHY
- Looped-back MAC via SGMII via Xilinx PCS/PMA core and LVDS IOSERDES
- SFP+ cages
- Looped-back 1000BASE-X via Xilinx PCS/PMA core and GTH transceiver
Board details
- FPGA: xcku040-ffva1156-2-e
- 1000BASE-T PHY: Marvell 88E1111 via SGMII
- 1000BASE-X PHY: Xilinx PCS/PMA core via GTH transceiver
Licensing
- Toolchain
- Vivado Enterprise (requires license)

- No licensed vendor IP or 3rd party IP
How to build
Run make in the appropriate fpga* subdirectory to build the bitstream. Ensure that the Xilinx Vivado toolchain components are in PATH.
How to test
Run make program to program the board with Vivado.
To test the looped-back UART, use any serial terminal software like minicom, screen, etc. The looped-back UART will echo typed text back without modification.
To test the looped-back MAC, it is recommended to use a network tester like the Viavi T-BERD 5800 that supports basic layer 2 tests with a loopback. Do not connect the looped-back MAC to a network as the reflected packets may cause problems.
