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

2. Create build directory

$ mkdir build
$ cd build

3. 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

4. Build HLS IP cores and install them into IP repository

$ make installip

5. Create vivado project

$ make project

6. Run synthesis

$ make synthesize

7. Run implementation

$ make implementation

8. Generate bitstream

$ make bitstream

Handling HLS IP cores

1. Setup build directory, e.g. for the dma_bench module

$ cd hls/dma_bench
$ mkdir build
$ cd build
$ cmake .. -DFPGA_PART=xcvu9p-flga2104-2L-e -DCLOCK_PERIOD=3.2

2. Run c-simulation

$ make csim

3. Run c-synthesis

$ make synthesis

4. Generate HLS IP core

$ make ip

5. Instal HLS IP core in ip repository

$ make installip
