This thing
This is me playing around with my new Icebreaker FPGA and nmigen(_dg). The goal is to find a nice project structure and perhaps find a way to work on my Arty a7 with a fully FOSS toolchain for once.
My focus is currently on:
* Effortless dependency management
* Helper functions for inspection and documentation of the design
* Helper functions for targeting multiple FPGA platforms and boards
* Creating PRs to other projects with stuff I come across here
* Having fun with my FPGA
Setup
pip install --user poetry
poetry config --local virtualenvs.in-project true # optional, makes cleanup easier
poetry install
And these optional dependencies, installed inside the virtualenv:
poetry install -E yosys
poetry install -E nextpnr-ice40
poetry install -E nextpnr-ecp5
Running stuff
poetry run python -m fpga.icebreaker
poetry run python -m fpga.modules.blinker generate
To reduce the amount of typing:
poetry shell
todo:
- Diagrams are nice
- Documentation generation would be nice
- A central nmigen-pmod repository would be nice
- A RISCV toolchain would be nice (make socs, and compile C, C++ or Rust)
- nextpnr-prxray or vpr would be nice
- Batch setup of Vivado would be nice
- Ability to synth on a host accessible with ssh would be nice
