Covered is programmed and documented by Trevor Williams
|
|
|
|
|
|
|
|
I would like to acknowledge certain individuals for their help in making Covered the tool that it is today.
|
|
|
|
- Stephen Williams - Thanks for helping me understand some of the ins and outs of what's required
"under the hood" to handle some of Verilog's constructs.
- Daniel McMahill - testing and patches for 64-bit compatibility

The Covered project has a user mailing list. Whenever there are stable releases being made of the
project, an e-mail will get sent out to this list stating the new release is available. Additionally, the
mailing list is a great way to bring up usability issues with the tool and, of course, bugs. The mailing
list can also be useful if you have a question about using Covered -- there is probably someone else
who has encountered the same problem that might be able to provide you with some help.

Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing
it is not allowed.
|
|
|
|
|
|
|
|
The licenses for most software are designed to take away your freedom to share and change it. By
contrast, the GNU General Public License is intended to guarantee your freedom to share and change
free software-to make sure the software is free for all its users. This General Public License applies
to most of the Free Software Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by the GNU Library General Public
License instead.) You can apply it to your programs, too.
|
|
|
|
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses
are designed to make sure that you have the freedom to distribute copies of free software (and charge
for this service if you wish), that you receive source code or can get it if you want it, that you can
change the software or use pieces of it in new free programs; and that you know you can do these things.
|
|
|
|
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to
ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
|
|
|
|
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the
recipients all the rights that you have. You must make sure that they, too, receive or can get the source
code. And you must show them these terms so they know their rights.
|
|
|
|
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which
gives you legal permission to copy, distribute and/or modify the software.
|
|
|
|
Also, for each author's protection and ours, we want to make certain that everyone understands that there
is no warranty for this free software. If the software is modified by someone else and passed on, we want
its recipients to know that what they have is not the original, so that any problems introduced by others
will not reflect on the original authors' reputations.
|
|
|
|
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that
redistributors of a free program will individually obtain patent licenses, in effect making the program
proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free
use or not licensed at all.
|
|
|
|
The precise terms and conditions for copying, distribution and modification follow.
|
|
|
|
|
|
|
|
- [0.] This License applies to any program or other work which contains a notice placed by
the copyright holder saying it may be distributed under the terms of this General Public License.
The ``Program'', below, refers to any such program or work, and a ``work based on the Program''
means either the Program or any derivative work under copyright law: that is to say, a work
containing the Program or a portion of it, either verbatim or with modifications and/or
translated into another language. (Hereinafter, translation is included without limitation in
the term ``modification''.) Each licensee is addressed as ``you''.
Activities other than copying, distribution and modification are not covered by this License;
they are outside its scope. The act of running the Program is not restricted, and the output
from the Program is covered only if its contents constitute a work based on the Program
(independent of having been made by running the Program). Whether that is true depends on what
the Program does.
- [1.] You may copy and distribute verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and appropriately publish on
each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty; and give any other
recipients of the Program a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option
offer warranty protection in exchange for a fee.
- [2.] You may modify your copy or copies of the Program or any portion of it, thus forming
a work based on the Program, and copy and distribute such modifications or work under the
terms of Section 1 above, provided that you also meet all of these conditions:
- [a.] You must cause the modified files to carry prominent notices stating that you
changed the files and the date of any change.
- [b.] You must cause any work that you distribute or publish, that in whole or in part
contains or is derived from the Program or any part thereof, to be licensed as a
whole at no charge to all third parties under the terms of this License.
- [c.] If the modified program normally reads commands interactively when run, you must
cause it, when started running for such interactive use in the most ordinary way, to
print or display an announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide a warranty) and
that users may redistribute the program under these conditions, and telling the user how
to view a copy of this License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on the Program is not required
to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work
are not derived from the Program, and can be reasonably considered independent and separate
works in themselves, then this License, and its terms, do not apply to those sections when
you distribute them as separate works. But when you distribute the same sections as part of
a whole which is a work based on the Program, the distribution of the whole must be on the
terms of this License, whose permissions for other licensees extend to the entire whole, and
thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work
written entirely by you; rather, the intent is to exercise the right to control the distribution
of derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with the Program (or with
a work based on the Program) on a volume of a storage or distribution medium does not bring the
other work under the scope of this License.
- [3.] You may copy and distribute the Program (or a work based on it, under Section 2) in object
code or executable form under the terms of Sections 1 and 2 above provided that you also do
one of the following:
- [a.] Accompany it with the complete corresponding machine-readable source code, which must
be distributed under the terms of Sections 1 and 2 above on a medium customarily used
for software interchange; or,
- [b.] Accompany it with a written offer, valid for at least three years, to give any third
party, for a charge no more than your cost of physically performing source distribution, a
complete machine-readable copy of the corresponding source code, to be distributed under
the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
- [c.] Accompany it with the information you received as to the offer to distribute corresponding
source code. (This alternative is allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such an offer, in accord with
Subsection b above.)
The source code for a work means the preferred form of the work for making modifications to it. For
an executable work, complete source code means all the source code for all modules it contains, plus
any associated interface definition files, plus the scripts used to control compilation and
installation of the executable. However, as a special exception, the source code distributed need not
include anything that is normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on which the executable runs, unless
that component itself accompanies the executable.
If distribution of executable or object code is made by offering access to copy from a designated place,
then offering equivalent access to copy the source code from the same place counts as distribution of
the source code, even though third parties are not compelled to copy the source along with the object
code.
- [4.] You may not copy, modify, sublicense, or distribute the Program except as expressly provided
under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License. However, parties who have received
copies, or rights, from you under this License will not have their licenses terminated so long as such
parties remain in full compliance.
- [5.] You are not required to accept this License, since you have not signed it. However, nothing else
grants you permission to modify or distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program
(or any work based on the Program), you indicate your acceptance of this License to do so, and all its
terms and conditions for copying, distributing or modifying the Program or works based on it.
- [6.] Each time you redistribute the Program (or any work based on the Program), the recipient
automatically receives a license from the original licensor to copy, distribute or modify the Program
subject to these terms and conditions. You may not impose any further restrictions on the recipients'
exercise of the rights granted herein. You are not responsible for enforcing compliance by third
parties to this License.
- [7.] If, as a consequence of a court judgment or allegation of patent infringement or for any other
reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement
or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions
of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may not distribute the Program
at all. For example, if a patent license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then the only way you could satisfy
both it and this License would be to refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the
balance of the section is intended to apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right
claims or to contest validity of any such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is implemented by public license practices.
Many people have made generous contributions to the wide range of software distributed through that
system in reliance on consistent application of that system; it is up to the author/donor to decide if
he or she is willing to distribute software through any other system and a licensee cannot impose that
choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of
this License.
- [8.] If the distribution and/or use of the Program is restricted in certain countries either by patents
or by copyrighted interfaces, the original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding those countries, so that distribution
is permitted only in or among countries not thus excluded. In such case, this License incorporates the
limitation as if written in the body of this License.
- [9.] The Free Software Foundation may publish revised and/or new versions of the General Public License
from time to time. Such new versions will be similar in spirit to the present version, but may differ
in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies a version number of this
License which applies to it and ``any later version'', you have the option of following the terms and
conditions either of that version or of any later version published by the Free Software Foundation. If
the Program does not specify a version number of this License, you may choose any version ever published
by the Free Software Foundation.
- [10.] If you wish to incorporate parts of the Program into other free programs whose distribution
conditions are different, write to the author to ask for permission. For software which is copyrighted by
the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for
this. Our decision will be guided by the two goals of preserving the free status of all derivatives of
our free software and of promoting the sharing and reuse of software generally.
NO WARRANTY
- [11.] BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE
EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR
IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD
THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
- [12.] IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER,
OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS

|
|
|
|
|
|
If you develop a new program, and you want it to be of the greatest possible use to the public, the best
way to achieve this is to make it free software which everyone can redistribute and change under these terms.
|
|
|
|
To do so, attach the following notices to the program. It is safest to attach them to the start of each
source file to most effectively convey the exclusion of warranty; and each file should have at least the
``copyright'' line and a pointer to where the full notice is found.
