A Minimal Chisel Project

A minimal Chisel project with Mill build system. This template is designed to be a starting point for new Chisel projects.

Directory Structure

  • .gitignore - Tell git to ignore some artifacts in the project.

  • Makefile - Rules to invoke the build system.

  • build.mill.scala - The mill build file for the project.

  • YourChiselProject/src/main/scala/Elaborate.scala - The main entry point for generating the hardware description files.

  • YourChiselProject/src/main/scala/YourChiselProject.scala - The main Chisel code for the project.

Getting Started

Installing Mill

If this is your first time using the Mill build system, please install the toolchain following their official instructions.

An example of the installation process is provided as follows:

Create a directory to store the toolchains.

mkdir -p ./toolchains/

Download the Mill binary and make it an executable.

curl -L https://repo1.maven.org/maven2/com/lihaoyi/mill-dist/0.13.0-M0/mill -o ./toolchains/mill
chmod +x ./toolchains/mill

Add the toolchain to the PATH.

export PATH="$PATH:$(pwd)/toolchains"

Now, mill should be available in the command line.

mill --version

Code Style
