Scalable Network Stack supporting TCP/IP, RoCEv2, UDP/IP at 10-100Gbit/s

Getting Started

Prerequisites

• Xilinx Vivado 2019.1
• cmake 3.0 or higher

Supported boards (out of the box)

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

Compiling (all) HLS modules and install them to your IP repository

0. Otionally specify the location of your IP repository:

export $IPREPO_DIR=/home/myname/iprepo

1. Create a build directory

mkdir build
cd build

2.a) Configure build

cmake .. -DDATA_WIDTH=64 -DCLOCK_PERIOD=3.1 -DFPGA_PART=xcvu9p-flga2104-2L-e -DFPGA_FAMILY=ultraplus -DVIVADO_HLS_ROOT_DIR=/opt/Xilinx/Vivado//2019.1/bin/

2.b)Alternatively you can use one the board name ot configure your build

cmake .. -DDEVICE_NAME=vcu118

All cmake 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 | | FPGA_PART | | Name of the FPGA part, e.g. xc7vx690tffg1761-2 | | FPGA_FAMILY | <7series,ultraplus> | Name of the FPGA part family | | DATA_WIDTH | <8,16,32,64> | Data width of the network stack in bytes | | CLOCK_PERIOD | | Clock period in nanoseconds, e.g. 3.1 for 100G, 6.4 for 10G | | TCP_STACK_MSS | | Maximum segment size of the TCP/IP stack | | TCP_STACK_WINDOW_SCALING_EN | <0,1> | Enalbing TCP Window scaling option | | VIVADO_HLS_ROOT_DIR | | Path to Vivado HLS directory, e.g. /opt/Xilinx/Vivado/2019.1 |

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

make installip

For an example project including the TCP/IP stack or the RoCEv2 stack with DMA to host memory checkout our Distributed Accelerator OS (DavOS).

Working with individual HLS modules

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

$ cd hls/toe
$ mkdir build
$ cd build
$ cmake .. -DFPGA_PART=xcvu9p-flga2104-2L-e -DDATA_WIDTH=8 -DCLOCK_PERIOD=3.1

2. Run c-simulation

$ make csim

3. Run c-synthesis

$ make synthesis

4. Generate HLS IP core

$ make ip

5. Instal HLS IP core into the IP repository

$ make installip
