# vga-square
Bounce a square around a VGA display using FPGA.
Targets Basys 3 Artix-7 board (XC7A35TCPG236-1).
## Development
This assumes Windows with WSL is used for FPGA development.
### Requirements
- Vivado 2023.2+
- GNU Make
- GTKWave
Verify Vivado is installed and its binaries (`xilinx/Vivado/2023.2/bin`) are in system path with `vivado -version`.
Also, verify GNU Make is installed with `make -v` and GTKWave is installed with `wsl -e gtkwave --version`.
### Workflow
Edit source in VS Code, the [vscode-verilog-hdl-support](https://github.com/mshr-h/vscode-verilog-hdl-support) extension seems to work well for Verilog and Tcl.
```sh
# build bitstream file
make build
# simulate, generate waveform, and open in gtkwave
make simulate
# build and upload bitstream to FPGA
make program_board
```
Optionally, you can still develop in project mode with the following:
```sh
# create Vivado project
make create_project
# open Vivado project in GUI
make gui
```
