===============================================================================================================================================================
---------------------
Starting your project
---------------------
1. To start the project you need to first create an empty Git project on Github and make sure your repo is public and includes a README
2. Open your Terminal. Create an empty folder to use as your Caravel workspace, and navigate to it.
.. code:: bash
# Create a directory and call it anything you want
mkdir -p caravel_tutorial
# navigate into the directory
cd caravel_tutorial
3. Clone caravel_user_project and setup the git environment as follows
.. code:: bash
# Make sure that ``caravel_example`` matches the empty github repo name in step 1
git clone -b mpw-5b https://github.com/efabless/caravel_user_project caravel_example
cd caravel_example
git remote rename origin upstream
# You need to put your empty github repo URL from step 1
git remote add origin <your github repo URL>
# Create a new branch, you can name it anything
git checkout -b <my_branch>
git push -u origin <my_branch>
4. Now that your git environment is setup, it's time to setup your local environment.
This command will install caravel_lite (a lite version of caravel), management core for simulation, openlane to harden your design and the pdk.
.. code:: bash
make setup
5. Now you can start hardening your design
To start hardening you project you need to have a RTL verilog model for your design for OpenLane to harden. You should then have a subdirectory for each module in your project under ``openlane/`` directory, this subdirectory should include your configuration files. Then you can harden using this command
.. code:: bash
make <module_name>
Example of a user project can be found by the name of ``user_proj_example``, the RTL can be found at ``verilog/rtl/user_proj_example.v`` and the configuration files can be found at ``openlane/user_proj_example``. And can be hardened using this command
**THIS IS JUST AN EXAMPLE**
.. code:: bash
make user_proj_example
6. You then need to integrate your modules into the user_project_wrapper. Then you can harden user_project_wrapper using this command
.. code:: bash
make user_project_wrapper
7. To run simulation on your design
You need to include your rtl files in ``verilog/includes/includes.<rtl/gl/gl+sdf>.caravel_user_project``. Then run the simulation using these commands
**NOTE:** You shouldn't include the files inside the verilog code
.. code:: bash
make simenv
# you can then run RTL simulations using
SIM=RTL make verify-<testbench-name>
# OR GL simulation using
SIM=GL make verify-<testbench-name>
# for example
SIM=RTL make verify-io_ports
8. To run the precheck locally
.. code:: bash
make precheck
make run-precheck
9. You are done! now go to www.efabless.com to submit your project!
