Introduction

This document describes the features and functions, and how to setup, operate, test, and

modify the 10GBASE-R Ethernet targeted reference design (10GBASE-R TRD).

10GBASE-R TRD Overview

The 10GBASE-R TRD targets the Kintex® UltraScale™ XCKU040-2FFVA1156E FPGA running

on the KCU105 evaluation board. It demonstrates 10-Gigabit Ethernet connectivity using

10-Gigabit Ethernet PCS/PMA IP (10GBASE-R) and 10-Gigabit Ethernet MAC IP (10G MAC)

cores on two channels. The data source for these channels can be configured to be either

from an internal or external Traffic Generator. Figure 1-1 shows the 10GBASE-R TRD block

diagram.

UG921 (v2016.3) October 25, 2016

Chapter 1: Introduction

The design has two 10 Gb/s Ethernet channels; channel 0 and channel 1. Data from one

channel is looped to the other as shown in Figure 1-1. Internal generator mode and external

generator mode are supported:

•Internal generator mode. In this mode, the Traffic Generator block generates the

transmit data. The data is looped back on the PHY side using fiber optic cables. The

looped-back data becomes the receive data on the other channel and is verified by the

10-Gigabit Ethernet MAC core.

•External generator mode. In this mode, an external generator generates the data.

Appendix D describes using an external Ixia NGY-NP4-01 10-Gigabit application

network processor load module (Ixia load module). The data received by the 10-Gigabit

Ethernet MAC IP core is looped back in the Traffic Generator block and passed as

transmit data to the other 10-Gigabit Ethernet MAC IP core. The Ixia load module

verifies this data when received.

A MicroBlaze™ processor-based subsystem monitors the 10-Gigabit Ethernet MAC IP core

statistics and passes the information to the Ethernet Controller application (GUI) running on

the control computer using the USB-to-UART port on the KCU105 board. This subsystem

also controls the Traffic Generator and monitors Ethernet performance.

Components, Features, and Functions

The 10GBASE-R TRD includes:

• 10-Gigabit Ethernet PCS/PMA IP core:

°Uses a GTH transceiver (GTHE3) running at 10.3125 Gb/s line rate.

°Provides a single data rate (SDR) 10-Gigabit Ethernet Media Independent Interface

(XGMII) which connects to the 10-Gigabit Ethernet MAC IP core. The XGMII interface

runs at 156.25 MHz and the data path is 64-bits wide.

°Serial interface to fiber-optic connections.

• 10-Gigabit Ethernet MAC IP core:

°Connects to the 10-Gigabit Ethernet PCS/PMA IP core using the XGMII interface

°Provides AXI4-Stream protocol support on the user interface running at 156.25 MHz

°Is monitored through an AXI4-Lite interface

• Traffic Generator and Monitor:

°Generates Ethernet traffic or loops back Ethernet traffic selected by user input

°Monitors bandwidth utilization on the transmit and receive AXI4-Stream interfaces

of the 10-Gigabit Ethernet MAC IP core

°Is configured and monitored through an AXI4-Lite interface

Chapter 1: Introduction

• System Management Wizard:

°Uses the UltraScale™ architecture System Monitor (SYSMON) block to monitor

FPGA temperature, voltages and currents

°Is configured and monitored through an AXI4-Lite interface

•AXIUARTLite:

°Provides the controller interface for asynchronous serial data transfer. This interface

connects to the USB-to-UART port on the KCU105 board, and is used to

communicate with the control computer.

°Provides an AXI4-Lite interface on the other end to communicate with the

MicroBlaze processor subsystem.

• MicroBlaze processor subsystem and AXI Interconnect:

°Communicates with the 10-Gigabit Ethernet MAC IP core, Traffic Generator and

Monitor, System Management wizard, and AXI UART Lite using the AXI4-Lite

protocol.

°Drivers running on the MicroBlaze processor subsystem interpret commands

received from the Ethernet Controller application running on the control computer

and convert them to AXI4-Lite transactions.

• Ethernet Controller application:

°Provides a graphical user interface running on the control computer to pass user

inputs to the 10GBASE-R TRD and to display status through the KCU105 board

USB-to-UART port.

Resource Utilization

Table 1-1 lists the resources used by the 10GBASE-R TRD after synthesis has run. Place and

route can alter these numbers based on placements and routing paths, so use these

numbers as a rough estimate of resource utilization. These numbers might vary based on

the version of the 10GBASE-R TRD and the tools used to regenerate the design.
