Manta's hardware-in-the-loop tests rely on Amaranth's build system for programming FPGAs, which in turn rely on the open-source `xc3sprog` and `iceprog` tools for programming Xilinx and ice40 devices, respecitvely. If you'd like to run these tests locally, you may need to install these tools and have them available on your `PATH`. If you're on Linux, you may also need to add a new udev rule to give non-superuser accounts access to any connected FTDI devices. This can be done by making a new file at `/etc/udev/rules.d/99-ftdi-devices.rules`, which contains:
It's recommended to place Manta on your system path by adding `export PATH="~/.local/bin:$PATH"` to your `.bashrc` or `.zshrc`. This isn't strictly necessary, but it means that Manta (and any other executable Python modules) can be run as just `manta` on the command line, instead of `python3 -m manta`. If you're on Windows, this location will likely be different.
- [Amaranth HDL](https://amaranth-lang.org/docs/amaranth/latest/), which comes with it's own built-in copy of Yosys.
- [LiteEth](https://github.com/enjoy-digital/liteeth), for sending and receiving UDP packets on the FPGA.
- [pySerial](https://pyserial.readthedocs.io/en/latest/index.html), for communicating with the FPGA over UART.
- [pyYAML](https://pyyaml.org/), for parsing configuration files written in YAML.
- [pyVCD](https://github.com/westerndigitalcorporation/pyvcd), for writing waveforms captured by the Logic Analyzer Core to standard Value Change Dump (VCD) files.
