Source License Version 3.1 (the “License”). You may not use this file except in compliance with such
restrictions and limitations. You may obtain instructions on how to receive a copy of the License at
http://www.accellera.org/. Software distributed by Contributors under the License is distributed
exclusively on an “AS IS” basis, WITHOUT WARRANTY OF ANY KIND, either express or
implied. See the License for the specific language governing rights and limitations under the License.”

4. REQUIREMENTS OF DISTRIBUTION

4.1 A Recipient may choose to Distribute any Contribution or any compilation of multiple Contributions
(except for any Code Contributions) under its own license agreement provided that:
(a) Recipient complies with the terms and conditions of this Agreement;
(b) As between Recipient and any other Contributor, Recipient assumes all warranties and conditions,
express and implied, and all liability for damages arising out of its Distribution; and
(c) Recipient makes available to recipients of such Distribution then Source Code for such
Distributions, and informs them on how to obtain it in a reasonable manner on or through a medium
customarily used for software exchange.
4.2 If a Recipient chooses to Distribute any Code Contribution or compilations of Code Contributions
then:
(a) Such Code Contribution must be Distributed under this Agreement; and
(b) A copy of this Agreement must be included with each copy of such Code Contribution.
4.3 Each Recipient must include the following in a conspicuous location in the Code Contribution so
Distributed: “Copyright© 1996-[current year here], by all Contributors. All rights reserved.”
4.4 In addition, each Recipient that creates and Distributes or otherwise transfers a Modification whether
or not such Modification has been deposited pursuant to Section 3 must identify the originator of such
Modification in a manner that reasonably allows third parties to identify the originator of the Modification.
4.5 A Recipient may choose to Distribute the Accellera Documentation under its own license agreement,
provided that Recipient complies with the terms and conditions of this Agreement. Each Recipient must
include the following in a conspicuous location in the Accellera Documentation so Distributed or transferred:
“Copyright© 1996-[current year here], by Accellera Systems Initiative. All rights reserved.”
In addition, each Recipient that creates and Distributes a modification or Derivative work of the Accellera
Documentation, whether or not such modification or Derivative work has been contributed pursuant to a
Copyright Agreement must identify the originator of such modification or Derivative work in a manner that
reasonably allows third parties to identify the originator of the modification or derivative work.

5. INDEMNIFICATION

Any Recipient which Distributes any Contribution and/or Accellera Release (a “Distributor”) may accept
certain responsibilities with respect to end users, business partners and the like. While this license is
intended to facilitate the commercial use of Contributions Accellera Documentation and Accellera
Releases, a Distributor shall Distribute such Contributions, Accellera Documentation and Accellera Releases
in a manner which does not create potential liability for the Contributors. Therefore each Distributor hereby
agrees to defend and indemnify every Contributor (“Indemnified Contributor”) against any losses,
damages and costs (collectively “Losses”) arising from claims, lawsuits and other legal actions brought
by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such
Distributor, including but not limited to the terms and conditions under which Distributor offered such
Contributions, Accellera Documentation and/or Accellera Releases in connection with its Distribution thereof.
The obligations in this Section 5 do not apply to any claims or Losses relating to any actual or alleged
intellectual property infringement of any Contribution, Accellera Documentation or Accellera Release. In
order to qualify, an Indemnified Contributor must: (a) promptly notify the Distributor in writing of such
claim, and (b) allow the Distributor to control, and cooperate with the Distributor in, the defense and any
related settlement negotiations. The Indemnified Contributor may participate in the defense of any such claim
at its own expense.
For example, a Recipient might include a Contribution in a commercial product offering, Product X. That
Recipient is then a Distributor. If that Distributor then makes performance claims, or offers warranties,
support, or indemnity or any other license terms related to Product X, those performance claims, offers and
other terms are such Distributor's responsibility alone. Under this Section 5, the Distributor would have to
defend claims against the Contributors related to those performance claims, offers, and other terms, and if a
court requires any Contributor to pay any damages as a result, the Distributor must pay those damages.

6. NO WARRANTY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, ALL CONTRIBUTIONS, ACCELLERA
DOCUMENTATION AND ACCELLERA RELEASES ARE PROVIDED EXCLUSIVELY ON AN “AS IS” BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING,

MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. EACH RECIPIENT IS SOLELY
RESPONSIBLE FOR DETERMINING THE APPROPRIATENESS OF ITS USE AND DISTRIBUTION OF ANY
CONTRIBUTION, ACCELLERA DOCUMENTATION AND ACCELLERA RELEASE AND ASSUMES ALL
RISKS ASSOCIATED WITH ITS EXERCISE OF RIGHTS UNDER THIS AGREEMENT, INCLUDING BUT NOT
LIMITED TO THE RISKS AND COSTS OF PROGRAM ERRORS, COMPLIANCE WITH APPLICABLE LAWS,
DAMAGE TO OR LOSS OF DATA, PROGRAMS OR EQUIPMENT, AND UNAVAILABILITY OR
INTERRUPTION OF OPERATIONS. THIS DISCLAIMER OR WARRANTY CONSTITUTES AN ESSENTIAL
PART OF THIS AGREEMENT. NO USE OF ANY CONTRIBUTION, ACCELLERA DOCUMENTATION OR
ACCELLERA RELEASE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.

7. DISCLAIMER OF LIABILITY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NONE OF THE RECIPIENTS, CONTRIBUTORS
OR ACCELLERA SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,
EXEMPLARY, PUNITIVE, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST
PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT
LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE
USE OR DISTRIBUTION OF ANY CONTRIBUTION, ACCELLERA DOCUMENTATION OR ACCELLERA
RELEASE OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

8. U.S. GOVERNMENT USE

If Recipient is licensing any computer program on behalf of any unit or agency of the United States
Government, then such computer program is commercial computer software, and, pursuant to FAR 12.212 or
DFARS 227.7202 and their successors, as applicable, shall be licensed to the Government under the terms and
conditions of this Agreement.

9. PATENT CLAIMS

If Recipient institutes patent litigation against any entity (including a cross-claim, counterclaim or declaratory
judgment claim in a lawsuit) alleging that any Contribution, Accellera Release or combination of
Contributions (excluding combinations of any Contribution with other software or hardware) infringes such
Recipient's patent(s), then the rights granted to Recipient by each Contributor under Section 2 shall terminate
as of the date such litigation is filed.

Trademark Usage Policy

I. LIST OF MARKS
1. Open SystemC
2. Open SystemC Initiative
3. OSCI
4. SystemC
5. SystemC Initiative
6. All logos that incorporate the foregoing word marks

II. PROPER USE OF MARKS
Trademarks and service marks function as adjectives and generally should not be used as nouns or verbs.
Accordingly, as often as possible, the Marks should be used as adjectives immediately preceding the generic
noun that refers to the service in question. For example:
The SystemC® software
The OSCI® LRM
No Possessives or Plurals. Since they are not nouns, the Marks should never be used in the possessive or
plural forms. For example, it is not appropriate to write “SystemC’s software.”
No Use as Verbs or as Puns. The Marks should never be used as verbs or as puns.

III. PROPER ATTRIBUTION
Trademark ownership is attributed in two ways, with the use of a symbol (TM, SM, ®) after the mark and with a
legal legend, usually found at the end of a document following the copyright notice. Following are Accellera’s
rules for symbols and legends to attribute the Marks:
Symbols:
Which Symbol Do I Use?
The Marks generally function as trademarks rather than service marks. Unless you are specifically directed
otherwise, please use the ® symbol after the Marks.
Where Do I Place the ® Symbol?
The ® symbol is placed immediately after the mark, either in superscript or subscript.
When Do I Use the Symbol?
The ® symbol is to be used after the Marks in the following instances:
Most Prominent Uses: A ® symbol is required after prominent uses of the Marks, e.g., in the headlines and
large print text of web pages, advertisements, other promotional materials and press releases, except where
space limitations or specific style considerations prevent compliance with this requirement.
First Use in Text: A ® symbol is required after the first use of each Mark in text, e.g. advertising copy or the
body of press releases, even though the symbol may have already appeared in the headline or after another
prominent use of the mark in the same document.
All Logos: The ® symbol must appear after all logos incorporating the Marks.

IV. LEGENDS
All Marks that appear on a web page or in a press release, advertisement or other written material (whether in
print or electronic form) must be attributed in an appropriate legend. The legend may be presented in
“mouseprint” but must be large enough to be read easily. Legends generally appear at the end of a document or
the bottom of a web page but may be placed elsewhere, e.g. the inside covers of documentation.
The Accellera Systems Initiative Legend: The following legend should be used in all materials in which any
of the Marks appear:
[Insert the Marks] are trademarks or registered trademarks of Accellera Systems Initiative, Inc. in the United
States and other countries and are used with permission.

V. MARKS NEVER COMBINED
The Marks should never be combined with the marks of any business other than Accellera. The Marks should
always appear visually separate from any other marks appearing in the same materials such that each mark
creates a distinct commercial impression. It would, for instance, not be appropriate to superimpose the logo of
another business over any Accellera logo.

VI. LOGOS
Logos incorporating the Marks can only be used in the format provided to you by Accellera for incorporation
into your materials or web pages. The logos provided to you by Accellera cannot be modified in any way
without Accellera’s prior written approval. Logos copied from Accellera web pages or other materials may not
to be used. Please contact info@accellera.org to obtain electronic files containing the Accellera logos and to
ask any question regarding the logos.
