2 Agenda Alveo Acceleration Cards Available Documentations Card Bring-Up and Validation Working with github SDAccel Examples Demo

3 Alveo Accelerator Cards Alveo U200 Alveo U250 Alveo U280 Available Now Available Now Coming Soon

4 Available Documentations Product Selection Guide Public Access Product and Solution Briefs Board Data Sheets Getting Started Guide

5 Alveo Board Installation Guide Unpacking Card Installation Procedures or or or UG1301 Installing the Deployment Software Card Bring-Up and Validation Installing the Development Software - UG1238

6 Before You Begin Minimum System Requirements UG1301 v2018.3

7 Prepare Your OS Required Dependencies for OS Choose suggested OS version Detailed Linux packages required d ependencies for OS are listed at UG Appendix A Make sure all those listed packages are installed at your OS before start to install XRT on it Choose Development Tools while install CentOS if installing OS from scratch Necessary Linux packages will be installed properly in this way If CentOS is ready but without Development Tools selected at installation Install those packages manually sudo yum install kernel-headers-$(uname -r) sudo yum install kernel-devel-$(uname -r) Do NOT use upgrade command which may upgrade OS to latest version that we don t support sudo yum upgrade

8 New Board Flow since XDF Software component installation based on Linux packages rpm for RedHat/CentOS or deb for Ubuntu Linux packages are standard Base component delivered as Linux packages XRT - Xilinx Runtime Deployment Shell Development Shell Application delivered as Linux packages More applications available at github Pre-compiled binary delivered with Deployment Shell to help confirm a board is working

2 for Deployment XRT + Deployment Shell Steps 1, 2, 3, 4

9 Getting Started Getting Started with Alveo U200 Select the desired tool version Select your OS version Steps 1, 2 for Deployment XRT + Deployment Shell Steps 1, 2, 3, 4 for Development XRT + Deployment Shell Development Shell + SDx

Getting Started The XRT and deployment shell must be installed prior to installing the development shell Alevo card has been flashed before ship out, but user might still need to update the card to

10 Getting Started The XRT and deployment shell must be installed prior to installing the development shell Alevo card has been flashed before ship out, but user might still need to update the card to the latest firmware using xbutil utility. First to check if the DSA running on FPGA matches the Deployment Shell (DSA) version installed at system sudo xbutil flash scan Then, if needed, flash your card to desired DSA version using the <shell name> and <timestamp> information displayed under the DSA package installed in system sudo xbutil flash -a <shell_name> -t <timestamp> Important If the card cannot be recognized by lspci properly, user can still revert the Alveo card to the image shipped from the factory AR# 71757

11 Deployment Flow for CentOS Step 1. Download and install the Xilinx Runtime Extra Packages for Enterprise Linux (EPEL) is prerequisite for XRT sudo yum install epel-release Download XRT for your OS and install it sudo yum install xrt_<version>.rpm Default installation directory /opt/xilinx/xrt Step 2. Download and install the Deployment Shell package Download proper package for your card and your OS sudo yum install xilinx-<card>-xdma-<version>.rpm Default installation directory /opt/xilinx/dsa

12 Development Flow for CentOS Step 1. & 2. are also needed Step 3. Download and install the Development Shell package Download proper package for your card and your OS sudo yum install xilinx-<card>-xdma-dev-<version>.rpm Default installation directory /opt/xilinx/platform This is the original platform folder that needed by xocc of SDAccel to generate xclbin Step 4. Download and install SDAccel Environment Current latest version of SDAccel that support Alveo board is version Default installation directory /opt/xilinx/sdx/2018.3

13 Deployment vs. Development Deployment only when an application is already available XRT + Deployment Shell No software license required Development with or without board XRT + Deployment Shell + Development Shell + SDx Deployment Shell always needed, even for Development flow Applications and software stacks Linux packages technology allow dependency management, installation of full software stacks

14 Linux Packages for Alveo and SDAccel Package Contents Distribution Dependency User Persona XRT Runtime including header files, tools, Linux kernel drivers Publicly available signed rpm/deb packages from Xilinx website One-time installation of the repo yum/apt install with no license check Base OS and system libraries Developer User Deployment Shell Image for flashing the board Pre-compiled binary to verify board Publicly available signed rpm/deb packages from Xilinx website One-time installation of the repo yum/apt install with no license check XRT package Developer User Development Shell Platform package for use by xocc and emulation tools Publicly available signed rpm/deb packages from Xilinx website One-time installation of the repo yum/apt install with no license check XRT package Deployment Shell package SDx tools Developer SDx tools xocc, Vivado, HLS Available from Xilinx website with licensing Developer

15 Evolution of Board Flow Recall of previous board flow Package Since xdf Before User Persona XRT rpm/deb available from Xilinx website Installed with SDAccel environment Also available as separate package after xbinst Developer User Deployment Shell rpm/deb available from Xilinx website Installation package/script available after xbinst Including XRT, FPGA firmware, drivers and xbsak utility. Developer User Development Shell rpm/deb available from Xilinx website DSA package installed with SDAccel environment Custom DSA package Developer SDx tools Installation Package Available from Xilinx website with licensing Developer

16 Additional Notes New flow introduced for Alveo boards since xdf The new flow becomes default in for VCU1525 as well XDF VCU1525 Scripts available with SDAccel Installation No need to upgrade to this release rpm / deb U200 Unsupported rpm / deb rpm / deb U250 Unsupported rpm / deb rpm / deb New XRT / DSA flow versus Boards

17 Card Bring-Up and Validation The xbutil Utility it s xbsak renamed since XDF Xilinx Board Utility installed with XRT package Previous xbsak utility is being deprecated Major Functions of xbutil Utility Card administration tasks Flash card configuration memory of the card Reset hung cards Query card status, sensors, and PCIe AER registers Debug operations Download the SDAccel binary to FPGA Test DMA for PCIe bandwidth Show status of compute units

The xbutil Utility $ xbutil help // list

reports board information $ xbutil validate

18 The xbutil Utility $ xbutil help // list available options $ xbutil list // list all boards on system $ xbutil scan // scan the drivers used for a board $ xbutil query // reports board information $ xbutil validate // validates if board has been setup properly

Working with SDAccel IDE Make sure XRT, Deployment Shell and Development Shell packages are all installed Setup the SDx environment source <SDx installation directory>/settings64.

19 Working with SDAccel IDE Make sure XRT, Deployment Shell and Development Shell packages are all installed Setup the SDx environment source <SDx installation directory>/settings64.(c)sh Point SDAccel to the XRT installation if it s NOT at the default installation directory source <XRT installation directory>/setup.(c)sh Point SDAccel to the Development Shell installation if it s NOT at the default installation directory setenv PLATFORM_REPO_PATHS <Development Shell installation directory> or export PLATFORM_REPO_PATHS=<Development Shell installation directory> Start SDx IDE environment sdx

20 Choose a Platform for SDAccel Project

21 Create Project from Built-in Example - vadd

22 Download github Examples to IDE Templates

23 Choose github Examples from IDE Templates

24 Choose github Examples from IDE Templates

25 Create Project from github Example

26 Working with github Examples in Makefile Mode Clone the proper branch that matches with the SDx tool version you re using Clone the branch with name matches the SDAccel version you are using. Don t use branch for xdf tool because Makefile has been changed to work with new XRT and board flow. Extra environment variable need to be set Setup the SDx environment Point SDAccel to the XRT installation since xdf Use make help to check proper command to use E.g. To run Software Emulation for U200 card

27 Download or Clone SDAccel Examples from github Always download or clone proper branch for your SDAccel version The master branch for newest SDAccel release Branch version name matches SDAccel version Download or clone entire branch even for one application Method 1. Download.zip file Method 2. git clone -b <Branch> <URL> git clone -b _xdf

28 Working SDAccel in Makefile Mode Make sure XRT, Deployment Shell and Development Shell packages are all installed Setup the SDx environment source <SDx installation directory>/settings64.(c)sh Point SDAccel to the XRT installation source <XRT installation directory>/setup.(c)sh Point SDAccel to the Development Shell installation if it s NOT at the default installation directory setenv PLATFORM_REPO_PATHS <Development Shell installation directory> or export PLATFORM_REPO_PATHS=<Development Shell installation directory>

29 Makefile Interpretation Every application has a Makefile file Makefile includes some other.mk files The board/device used for compilation can be changed by adding the DEVICE variable to the make command CXXFLAGS for host compiler settings CLFLAGS for kernel compiler settings make host can be used to only compile host executable file Use make help to check proper command to use for every compiling or execution steps

30 Run Software/Hardware Emulation Compiling for application emulation make all TARGET=sw_emu DEVICE=xilinx_u200_xdma_201820_1 or make all TARGET=hw_emu DEVICE=xilinx_u200_xdma_201820_1 Executing emulated application make check TARGET=sw_emu DEVICE=xilinx_u200_xdma_201820_1 or make check TARGET=hw_emu DEVICE=xilinx_u200_xdma_201820_1 If the application has not been previously compiled, the check makefile rule will compile and execute the application in the emulation mode selected by user Hardware Emulation normally cost more time than Software Emulation Environment for Emulation will be automatically setup by makefile and profile summary report in html format will be automatically generated by makefile too

31 On Board Complication and Execution Compiling for on-board executable application make all TARGET=hw DEVICE=xilinx_u200_xdma_201820_1 Executing application on board make check TARGET=hw DEVICE=xilinx_u200_xdma_201820_1 If the application has not been previously compiled, the check makefile rule will compile and execute the application on board The default target for the makefile is to compile for hardware Once the environment has been configured, the application can also be executed by directly executing exe file.
