Licensing
|
|
=========
|
|
|
|
Distribution of the PeakRDL-regblock code generator tool shall adhere to the
|
|
terms outlined by the GNU GPL v3 license. For a copy of the license, see:
|
|
https://github.com/SystemRDL/PeakRDL-regblock/blob/main/LICENSE
|
|
|
|
|
|
Why GPL?
|
|
--------
|
|
GPL was chosen because my intent is to promote a thriving ecosystem of free and
|
|
open source register automation tools. GPL discourages this tool to be bundled
|
|
into some commercially sold closed-source software, as that would be contrary to
|
|
this project's philosophy.
|
|
|
|
|
|
What is covered by the GPL v3 license?
|
|
--------------------------------------
|
|
The GPL license is intended for the code generator itself. This includes all
|
|
Python sources, Jinja demplate files, as well as testcase infrastructure not
|
|
explicitly mentioned in the exemptions below.
|
|
|
|
|
|
What is exempt from the GPL v3 license?
|
|
---------------------------------------
|
|
Don't worry. Not everything that the PeakRDL-regblock project touches is
|
|
considered GPL v3 code.
|
|
|
|
The following are exempt and are free to use with no restrictions:
|
|
|
|
* Any code that is generated using PeakRDL-regblock is 100% yours. Since it
|
|
was derived from your regblock definition, it remains yours. You can
|
|
distribute it freely, use it in a proprietary ASIC, sell it as part of an
|
|
IP, whatever.
|
|
* Any code snippets in this documentation can be freely copy/pasted. These are
|
|
examples that are intended for this purpose.
|
|
* All reference files that are downloadable from this documentation, which are
|
|
also available in the `hdl-src folder in the repository <https://github.com/SystemRDL/PeakRDL-regblock/tree/main/hdl-src>`_
