HDL Git repository
|
|
===============================================================================
|
|
|
|
All the HDL sources can be found in the following git repository:
|
|
|
|
:git-hdl:`/`
|
|
|
|
We assume that the user is familiar with `git <https://git-scm.com/>`__.
|
|
Knows how to
|
|
`clone <https://git-scm.com/book/en/v2/Git-Basics-Getting-a-Git-Repository>`__
|
|
the repository, how to check its
|
|
`status <https://git-scm.com/docs/git-status>`__ or how to
|
|
`switch <https://git-scm.com/book/en/v2/Git-Branching-Basic-Branching-and-Merging>`__
|
|
between branches.
|
|
|
|
.. note::
|
|
|
|
A basic git knowledge is required in order to work with these source files,
|
|
if you do not have any, don't worry!
|
|
|
|
There are a lot of great resources and tutorials about git all over the
|
|
`web <http://lmgtfy.com/?q=git+tutorial>`__.
|
|
|
|
|
|
If you want to pull down the sources as soon as possible, just do the
|
|
following few steps:
|
|
|
|
#. Install Git from `here <https://git-scm.com/>`__
|
|
#. Open up Git bash, change your current directory to a place where you
|
|
want to keep the hdl source
|
|
#. Clone the repository using
|
|
`these <https://help.github.com/articles/cloning-a-repository/>`__
|
|
instructions
|
|
|
|
Folder structure
|
|
-------------------------------------------------------------------------------
|
|
|
|
The root of the HDL repository has the following structure:
|
|
|
|
.. code-block::
|
|
|
|
.
|
|
+-- .github
|
|
+-- docs
|
|
+-- library
|
|
+-- projects
|
|
+-- scripts
|
|
+-- Makefile
|
|
+-- README.md
|
|
+-- LICENSE
|
|
|
|
The repository is divided into 5 separate sections:
|
|
|
|
- **.github** with all our automations regarding coding checks, GitHub actions
|
|
- **docs** with our GitHubIO documentation and regmap source files
|
|
- **library** with all the Analog Devices Inc. proprietary IP cores and
|
|
hdl modules, which are required to build the projects
|
|
- **projects** with all the currently supported projects
|
|
- **scripts** with our environment scripts that set tools versions, etc.
|
|
|
|
The file **.gitattributes** is used to properly `handle
|
|
different <https://help.github.com/articles/dealing-with-line-endings/>`__
|
|
line endings. And the **.gitignore** specifies intentionally untracked
|
|
files that Git should ignore. The root **Makefile** can be used to build
|
|
all the project of the repository. To learn more about hdl **Makefiles**
|
|
visit the :ref:`Building & Generating programming files <build_hdl>` section.
|
|
|
|
The projects are structured as follows
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Besides the project folders, there are two special folders inside the
|
|
**/hdl/projects**:
|
|
|
|
- **common**: This folder contains all the base designs, for all
|
|
currently supported FPGA development boards. Be aware if you see your
|
|
board on this list, it does not necessarily mean that you can use it
|
|
with your FMC board.
|
|
- **scripts**: In all cases, we are interacting with the development
|
|
tools (Vivado/Quartus) using Tcl scripts. In this folder are defined
|
|
all the custom Tcl processes, which are used to create a project,
|
|
define the system and generate programming files for the FPGA.
|
|
|
|
Inside a project folder, you can find folders with an FPGA carrier name
|
|
(e.g. ZC706) which in general contains all the carrier board specific
|
|
files, and a folder called **common** which contains the project
|
|
specific files. If you can not find your FPGA board name in a project
|
|
folder, that means your FPGA board with that particular FMC board is not
|
|
supported.
|
|
|
|
The library are structured as follows
|
|

The library folder contains all the IP cores and common modules. An IP,
|
|
in general, contains Verilog files, which describe the hardware logic,
|
|
constraint files, to ease timing closure, and Tcl scripts, which
|
|
generate all the other files required for IP integration (\*_ip.tcl for
|
|
Vivado and \*_hw.tcl for Quartus) .
|
|
|
|
.. note::
|
|
|
|
Regarding Vivado, all the IPs must be 'packed' before being used in a
|
|
design.
|
|
|

Repository releases and branches
|
|
-------------------------------------------------------------------------------
|
|
|
|
The repository may contain multiple branches and tags. The
|
|
:git-hdl:`main </>` branch
|
|
is the development branch (latest sources, but not stable). If you check
|
|
out this branch, some builds may fail. If you are not into any kind of
|
|
experimentation, you should only check out one of the release branch.
|
|
|
|
All our release branches have the following naming convention:
|
|
**hdl\_**\ [year_of_release]\ **\_r**\ [1 or 2]. (e.g.
|
|
:git-hdl:`hdl_2014_r2 <hdl_2014_r2:>`)
|
|
|
|
ADI does two releases each year when all the projects get an update to
|
|
support the latest tools and get additional new features. \*\* The
|
|
main branch is always synchronized with the latest release.*\* If you
|
|
are in doubt, ask us on :ez:`fpga`.
|
|
|
|
.. note::
|
|
|
|
You can find the release notes on the GitHub page of the
|
|
repository:
|
|
|
|
https://github.com/analogdevicesinc/hdl/releases
|
|
|
|
The latest version of tools used on main can be found at:
|
|
:git-hdl:`scripts/adi_env.tcl` (*required_vivado_version* and
|
|
*required_quartus_version* variables). For Intel Quartus Standard, the version
|
|
is specified in each project that uses it, depending on the carrier.
