# Taxi Example Design for HTG-940
|
|
|
|
## Introduction
|
|
|
|
This example design targets the HiTech Global HTG-940 FPGA board.
|
|
|
|
The design places a looped-back MAC on the BASE-T port, as well as a looped-back UART on on the USB UART connection.
|
|
|
|
* USB UART
|
|
* Looped-back UART
|
|
* RJ-45 Ethernet ports with TI DP83867IRPAP PHY
|
|
* Looped-back MAC via RGMII
|
|
|
|
## Board details
|
|
|
|
* FPGA: xcvu9p-flgb2104-2-e
|
|
* 1000BASE-T PHY: TI DP83867IRPAP via RGMII
|
|
|
|
## Licensing
|
|
|
|
* Toolchain
|
|
* Vivado Enterprise (requires license)
|
|
* IP
|
|
* 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.
