You've done the chisel tutorials, and now you are ready to start your own chisel project. The following procedure should get you started with a clean running Chisel3 project.

The first thing you want to do is clone this repo into a directory of your own. I'd recommend creating a chisel projects directory somewhere

mkdir ~/ChiselProjects
cd ~/ChiselProjects

git clone https://github.com/ucb-bar/chisel-template.git MyChiselProject
cd MyChiselProject

There may be more elegant way to do it, but the following works for me. Note: this project comes with a magnificent 339 line (at this writing) .gitignore file. You may want to edit that first in case we missed something, whack away at it, or start it from scratch.

rm -rf .git
git init
git add .gitignore *
git commit -m 'Starting MyChiselProject'

Connecting this up to github or some other remote host is an exercise left to the reader.

You should now have a project based on Chisel3 that can be run. Note: With a nod to cargo cult thinking, some believe it is best to execute the following sbt before opening up this directory in your IDE. I have no formal proof of this assertion. So go for it, at the command line in the project root.

sbt test

You should see a whole bunch of output that ends with something like the following lines

STEP 1092 -> 1102
  EXPECT GCD.io_z -> 0x4 == 0x4 PASS
  EXPECT GCD.io_v -> 0x1 == 0x1 PASS

If you see the above then...

You are ready to go. We have a few recommended practices and things to do.

• Use packages and following conventions for structure and naming
• Package names should be clearly reflected in the testing hierarchy
• Build tests for all your work.
• This template includes a dependency on the Chisel3 IOTesters, this is a reasonable starting point for most tests
• You can remove this dependency in the build.sbt file if necessary
• Change the name of your project in the build.sbt
• Change your README.md

This is the release version of chisel-template. If you have bug fixes or changes you would like to see incorporated in this repo, please checkout the master branch and submit pull requests against it.
