Additional permissions under section 7 of the GNU General Public License
(GPL) are hereby granted. The purpose of this exception is to allow
non-GPL (including proprietary) logic cores to be used in conjunction
with code generated by Migen in a design.

"Generated" code refers to Verilog or VHDL code that has been obtained
by converting FHDL structures using Migen.

To "instantiate" is to include and connect another module as specified
in section 12.1.2 of the IEEE standard 1364-2001 or in section 9.6 of
the IEEE standard 1076-1993.

(1) You have permission to propagate a work of generated code that
instantiates modules that are not generated code and do not comply
with the GPL.
(2) You have permission to propagate a work of Verilog or VHDL code that
is not generated code, does not comply with the GPL and instantiates
generated code.

The availability of this exception does not imply any general
presumption that third-party software is unaffected by the copyleft
requirements of the license of Migen.

Unless otherwise noted, Migen's source code is copyright (C) 2011-2012

of the corresponding source files) is copyright (C) 2012 Vermeer

can reasonably be considered independently copyrightable, it's yours and
I encourage you to claim it with appropriate copyright notices. This
submission then falls under the "otherwise noted" category. All

above.

Migen is designed for Python 3.3.

Migen is released under the very permissive two-clause BSD license. Under the
terms of this license, you are authorized to use Migen for closed-source
proprietary designs.
Even though we do not require you to do so, those things are awesome, so please
do them if possible:
* tell us that you are using Migen
* put the Migen logo (doc/migen_logo.svg) on the page of a product using it,
with a link to milkymist.org
* cite Migen in publications related to research it has helped
* send us feedback and suggestions for improvements
* send us bug reports when something goes wrong
* send us the modifications and improvements you have done to Migen. The use
of "git format-patch" is recommended. If your submission is large and
complex and/or you are not sure how to proceed, feel free to discuss it on
the mailing list or IRC (#milkymist on Freenode) beforehand.
