Chisel Project Template ======================= You've done the chisel [tutorials](https://github.com/ucb-bar/chisel-tutorial.git), and now you are ready to start your own chisel project. The following procedure should get you started with a clean running [Chisel3](https://github.com/ucb-bar/chisel3.git) project. ## Make your own Chisel3 project ### How to get started 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 ```sh mkdir ~/ChiselProjects cd ~/ChiselProjects git clone https://github.com/ucb-bar/chisel-template.git MyChiselProject cd MyChiselProject ``` ### Make your project into a fresh git repo 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. #### Clear out the old git stuff ```sh rm -rf .git git init git add .gitignore * ``` #### Rename project in build.sbt file Use your favorite text editor to change the first line of the **build.sbt** file (it ships as ```name := "chisel-module-template"```) to correspond to your project.
Perhaps as ```name := "my-chisel-project"``` #### Clean up the README.md file Again use you editor of choice to make the README specific to your project. Be sure to update (or delete) the License section and add a LICENSE file of your own. #### Commit your changes ``` git commit -m 'Starting MyChiselProject' ``` Connecting this up to github or some other remote host is an exercise left to the reader. ### Did it work? You should now have a project based on Chisel3 that can be run.
So go for it, at the command line in the project root. ```sh sbt 'testOnly gcd.GCDTester -- -z Basic' ``` >This tells the test harness to only run the test in GCDTester that contains the word Basic There are a number of other examples of ways to run tests in there, but we just want to see that one works. You should see a whole bunch of output that ends with something like the following lines ``` [info] [0.001] SEED 1506028591907 test GCD Success: 168 tests passed in 1107 cycles taking 0.203969 seconds [info] [0.191] RAN 1102 CYCLES PASSED[info] GCDTester: [info] GCD [info] GCD [info] Basic test using Driver.execute [info] - should be an alternative way to run specification [info] using --backend-name verilator [info] running with --is-verbose creats a lot [info] using --help [info] ScalaTest [info] Run completed in 1 second, ***2 milliseconds. [info] Total number of tests run: 1 [info] Suites: completed 1, aborted 0 [info] Tests: succeeded 1, failed 0, canceled 0, ignored 0, pending 0 [info] All tests passed. [info] Passed: Total 1, Failed 0, Errors 0, Passed 1 [success] Total time: 2 s, completed Sep 21, 2017 9:12:47 PM ``` If you see the above then... ### It worked! You are ready to go. We have a few recommended practices and things to do. * Use packages and following conventions for [structure](http://www.scala-sbt.org/0.13/docs/Directories.html) and [naming](http://docs.scala-lang.org/style/naming-conventions.html) * 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 ## Development/Bug Fixes This is the release version of chisel-template.
