Licensing
|
|
=========
|
|
|
|
Re-distribution of the PeakRDL-busdecoder code generator tool shall adhere to the
|
|
terms outlined by the GNU LGPL v3 license. For a copy of the license, see:
|
|
https://github.com/SystemRDL/PeakRDL-busdecoder/blob/main/LICENSE
|
|
|
|
|
|
Why LGPLv3?
|
|
-----------
|
|
LGPLv3 was chosen because my intent is to promote a thriving ecosystem of free and
|
|
open source register automation tools. The license terms discourage this tool from
|
|
being bundled into some commercially sold closed-source software, as that would
|
|
be contrary to this project's philosophy.
|
|
|
|
|
|
What is covered by the LGPL v3 license?
|
|
--------------------------------------
|
|
The LGPL license is intended for the code generator itself. This includes all
|
|
Python sources, Jinja template files, as well as testcase infrastructure not
|
|
explicitly mentioned in the exemptions below.
|
|
|
|
|
|
What is exempt from the LGPLv3 license?
|
|
---------------------------------------
|
|
Don't worry. Not everything that the PeakRDL-busdecoder project touches is
|
|
considered LGPLv3 code.
|
|
|
|
The following are exempt and are free to use with no restrictions:
|
|
|
|
* Any code that is generated using PeakRDL-busdecoder is 100% yours. Since it
|
|
was derived from your busdecoder 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-busdecoder/tree/main/hdl-src>`_
|
|
|
|
|
|
Can I use this as part of my company's internally developed tools?
|
|
------------------------------------------------------------------
|
|
Absolutely!
|
|
|
|
Sometimes it may be necessary to integrate this into a larger toolchain at your
|
|
workplace. This is totally OK, as long as you don't start distributing it
|
|
outside your workplace in ways that violate the LGPLv3 license.
|
|
|
|
That said, I'd encourage you to check out the `PeakRDL command line tool <https://peakrdl.readthedocs.io/>`_.
|
|
It may already do everything you need.
