A compiler for Copilot targeting FPGAs.

This package is a back-end from Copilot to FPGAs in Bluespec.

Copilot is a stream (i.e., infinite lists) domain-specific language (DSL) in Haskell. Copilot contains an interpreter, multiple back-end compilers, and other verification tools.

A tutorial, examples, and other information are available at https://copilot-language.github.io.

Copilot: a stream DSL

Copilot-Bluespec implements a Bluespec backend for Copilot, producing code that is suitable for FPGAs.

Copilot is a runtime verification framework written in Haskell. It allows the user to write programs in a simple but powerful way using a stream-based approach.

Programs can be interpreted for testing, or translated Bluespec code to be incorporated in a project, or as a standalone application. The Bluespec backend ensures us that the output is constant in memory and time, making it suitable for systems with hard realtime requirements.

Installation

Copilot-Bluespec can be found on Hackage. It is intended to be installed alongside a Copilot distribution by running the following commands:

$ cabal update
$ cabal install copilot
$ cabal install copilot-bluespec

For more detailed instructions on how to install Copilot, please refer to the Copilot website.

The generated Bluespec code requires bsc (the Bluespec compiler) in order to be compiled. bsc can be downloaded here.

We also provide a Dockerfile which automates the process of installing Copilot, Copilot-Bluespec, and bsc. The Dockerfile can be built and run using the following commands:

$ docker build -t <tag> .
$ docker run -it <tag>

Where <tag> is a unique name for the Docker image.
