DavOS (Distributed Accelerator OS)

Prerequisites

  • Xilinx Vivado 2019.1
  • cmake 3.0 or higher
  • Linux OS
  • Xilinx licenses for board/chip and Ethernet cores

Supported boards (out of the box)

  • Xilinx VC709
  • Xilinx VCU118
  • Alpha Data ADM-PCIE-7V3

Build project

  1. Initialize submodules
$ git clone git@github.com:fpgasystems/davos.git
$ git submodule update --init --recursive
  1. Create build directory
$ mkdir build
$ cd build
  1. Configure build
$ cmake .. -DDEVICE_NAME=vcu118 -DTCP_STACK_EN=1 -DVIVADO_ROOT_DIR=/opt/Xilinx/Vivado/2019.1/bin -DVIVADO_HLS_ROOT_DIR=/opt/Xilinx/Vivado/2019.1/bin

All options:

Name Values Desription
DEVICE_NAME <vc709,vcu118,adm7v3> Supported devices
NETWORK_BANDWIDTH <10,100> Bandwidth of the Ethernet interface in Gbit/s, default depends on board
ROLE_NAME Name of the role, default:. benchmark_role
ROLE_CLK <net,pcie> Main clock used for the role, default: net
TCP_STACK_EN <0,1> default: 0
UDP_STACK_EN <0,1> default: 0
ROCE_STACK_EN <0,1> default: 0
VIVADO_ROOT_DIR Path to Vivado HLS directory, e.g. /opt/Xilinx/Vivado/2019.1
VIVADO_HLS_ROOT_DIR Path to Vivado HLS directory, e.g. /opt/Xilinx/Vivado/2019.1
  1. Build HLS IP cores and install them into IP repository
$ make installip

  1. Run c-simulation
$ make csim
  1. Run c-synthesis
$ make synthesis
  1. Generate HLS IP core
$ make ip
  1. Instal HLS IP core in ip repository
$ make installip
