LiteX Build Environment

The LiteX Build Environment is a tool for easily developing LiteX based systems. It was originally designed to make the TimVideos' HDMI2USB easy to develop, but has now expanded to support multiple projects.

Boards

The LiteX Build Environment supports a large number of FPGA boards, but not all boards can be used for all projects.

Firmware

Gateware

The Gateware is the configuration which generates our FPGA bitstream. It is generally defined by a platform and a target. You can find details for these under the platform and target directories in this project.

Environment

The environment is the shell setup and software packages provided by litex-buildenv which allow for litex based FPGA development. It provides development, build and troubleshooting capabilities.

To bootstrap or update your environment one generally does:

# Install system wide dependencies;
#  * wget
#  * bash
#  * make
#  * udev rules from https://github.com/litex-hub/litex-buildenv-udev
#
# On Debian you can use the ./scripts/debian-setup.sh script.

# Download/update the litex specific packages (python, verilator, submodules etc)
./scripts/download-env.sh

# Enter the Dev/Debug/Build environment
export PLATFORM=arty TARGET=net CPU=or1k
source ./scripts/enter-env.sh
