SymbiFlow examples

This repository provides example FPGA designs that can be built using the SymbiFlow open source toolchain. The examples target the Xilinx Artix-7 and the QuickLogic EOS S3 devices.

The repository includes:

• eos-s3 - Example FPGA designs for the QuickLogic EOS S3 series of parts:

  • Verilog code
  • Pin constraints files
  • Timing constraints files
  • Makefiles for running the SymbiFlow toolchain

• xc7 - Example FPGA designs for the Xilinx 7 series of parts:

  • Verilog code
  • Pin constraints files
  • Timing constraints files
  • Makefiles for running the SymbiFlow toolchain

• .travis.yml - Travis CI configuration file

Toolchain installation

This section describes how to install the toolchain. This procedure is divided in two steps:

• Installing the Conda package manager
• Downloading the architecture definitions and installing the toolchain

1. Conda

wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh -O conda_installer.sh

2. Toolchain

• For the Artix-7 devices see xc7/README.md.

• For the EOS S3 devices see eos-s3/README.md.

Build Example Designs

With the toolchain installed, you can build the example designs. The example designs are provided in separate directories:

• xc7 directory for the Artix-7 devices
• eos-s3 directory for the EOS S3 devices

Example designs for the Artix-7 devices:

• For the Artix-7 devices see xc7/README.md.

Example design for the EOS S3 devices:

• For the EOS S3 devices see eos-s3/README.md.
