# Taxi Example Design for Nexus K35-S/K3P-S (ExaNIC X10/X25)
|
|
|
|
## Introduction
|
|
|
|
This example design targets the Cisco Nexus K35-S/K3P-S (ExaNIC X10/X25) FPGA board.
|
|
|
|
The design places looped-back MACs on the SFP+ cages.
|
|
|
|
* SFP+ cages
|
|
* Looped-back 10GBASE-R or 25GBASE-R MAC via GTH or GTY transceiver
|
|
|
|
## Board details
|
|
|
|
* FPGA:
|
|
* K35-S/X10: xcku035-fbva676-2-e
|
|
* K3P-S/X235: xcku3p-ffvb676-2-e
|
|
* 25GBASE-R PHY: Soft PCS with GTH or GTY transceiver
|
|
|
|
## Licensing
|
|
|
|
* Toolchain
|
|
* Vivado Standard (enterprise license not required)
|
|
* 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 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.
