FPGA - Guidance

Getting started

  1. Install dependencies if you haven't. In Powershell:
pip install matplotlib
pip install intel-jtag-uart

  1. Using Quartus, open up Tools > Programmer, then flash the FPGA using the top.sof file attached.

  2. Open up the NIOS II terminal. Run these commands:

# You may or may not need to run this command
export PATH=$PATH:$QUARTUS_ROOTDIR/../nios2eds/bin/gnu/H-x86_64-mingw32/bin/

cd fpga/software
./generate_app.sh

# You can run this command straight away if you don't need to change main.c
nios2-download -g app/main.elf
  1. Using Powershell, open up demo.py to test that the NIOS II hardware and software have been programmed correctly.
python fpga/vm/demo.py

Documentation

Quartus

Contains the RTL and testbench for hardware modules. The .sopcinfo file contains the information necessary to build the BSP (board support package) in the software folder.

To use the testbench you need to install GTest and Verilator

sudo apt install libgtest-dev

To install Verilator, you need to compile it from source to get the latest version. Follow the instructions on the GitHub.

Software

Contains the apps and the BSP required. A script is used to generate the apps. To create a new app, create a new app folder, and follow the bash script to generate the application makefile, which is used to generate the .elf used to flash the board.

VM

See vm/README.md
