BVF Bitstream Builder
Introduction
The BVF bitstream builder is a Python script that builds both the PolarFire SoC HSS bootloader and Libero FPGA project into a single programming bitstream. It uses a list of repositories/branches specifying the configuration of the BVF to build.
Prerequisites
Python libraries
The following Python libraries are used:
- GitPython
- PyYAML
pip3 install gitpython
pip3 install pyyamlMicrochip Tools
The SoftConsole and Libero tools from Microchip are required by the bitstream builder.
The following environment variables are required for the bitstream builder to use the Microchip tools:
- SC_INSTALL_DIR
- FPGENPROG
- LIBERO_INSTALL_DIR
- LM_LICENSE_FILE
An example script for setting up the environment is available here.
Usage
