AD9208-DUAL-EBZ Virtex UltraScale+ VCU118 Quick Start Guide

This guide provides some quick instructions (still takes awhile to download, and set things up) on how to setup the AD9208-DUAL-EBZ on the VCU118 platform.

The ADCs are set to run at full bandwidth mode 3 GSPS, which translates to a lane rate of 15.5 Gbps. Each converter has its own SYSREF that is driven from a common clock chip HMC7044. Ideally these SYREF lines should be length matched, if not the HMC has capability to adjust delays on its outputs. Sampling clocks are generated by the same HMC clock chip and should be ideally length matched as well.

Design and Integration Files

Schematic, Gerber layout and BOM

Prerequisites

Required Hardware

  • Xilinx VCU118 Rev 1.0 or later board
  • AD9208-DUAL-EBZ FMC board.
  • 2 x Micro-USB cable
  • Ethernet cable
  • Signal generator
  • 4 way splitter (optional)

Required Software

  • A Linux OS on a PC
  • Xilinx Vivado 2019.1 or later
  • UART terminal (e.g TeraTerm)
  • IIO Scope Download

Board setup

There are two options for powering the board, both require a rework :
  • In order to supply the board from the FMC connector populate F1 with a 2A fuse. Use this method if you can ensure the FMC carrier can drive 2A on its 12V power line.
  • Use an external 12V power supply and connect it to the TP1 (PWR_IN) and TP2 (AGND) points.

Steps

1. Build the HDL project

Before building the hdl project setup your computer based on the following guide: Building HDL projects 

git clone https://github.com/analogdevicesinc/hdl.git
git checkout hdl_2019_r2;  // or latest release
cd hdl/projects/ad9208_dual_ebz/vcu118
make
Prebuild files for boards with 125MHz VCXO can be downloaded from here

2. Build the Linux files

Instructions on how to build the MicroBlaze Linux kernel and devicetrees from source can be found here: 

make simpleImage.vcu118_dual_ad9208
Prebuild files for boards with 125MHz VCXO can be downloaded from here

3. Program the board

First we need to prepare a working directory where we will gather all the required binary files.
From the HDL build directory locate the system_top.bit and copy it to the working directory. From the Linux build directory locate the simpleImage and copy it to the working directory. 

mkdir <working_dir>
cp <hdl_repo_dir>/projects/ad9208_dual_ebz_vcu118.runs/impl_1/system_top.bit  <working_dir>
cp <linux_repo_dir>/arch/microblaze/boot/simpleImage.vcu118_dual_ad9208  <working_dir>

Next step is to program the board with xsct or similar tool. See generic instructions for programming the MicroBlaze bases systems here Boot Kernel on FPGA Microblaze 

xsct% connect
xsct% fpga -f system_top.bit
xsct% after 1000
xsct% target 3
xsct% dow simpleImage.vcu118_dual_ad9208.strip
xsct% after 1000
xsct% con
xsct% disconnect

The following devices should be present:

This specifies any shell prompt running on the target 

# iio_info | grep iio:device
        iio:device0: hmc7044
        iio:device1: axi-ad9208-0-hpc (buffer capable)
        iio:device2: axi-ad9208-1-hpc

4. Connect to board with IIO Scope

From the UART console find out the board IP address that was allocated by the DHCP server. If you do not use a DHCP server manually assign an IP to the board Ethernet port. The default username:password for Linux is root:analog.

5. Capture data with IIO Scope

JESD SubClass 0 example

When the device is configured from device tree into subclass 0 we can observe the two links are not synchronized and the channels present phase differences. Subclass 0

JESD SubClass 1 example

When the devices are configured into subclass 1 (default), we can observe the JESD links are synchronized and there is no phase difference between the input channels. Subclass 1

Support

Analog Devices will provide limited online support for anyone using the core with Analog Devices components (ADC, DAC, Video, Audio, etc) via the EngineerZone.
