2、 IEEE is a registered trademark in the U.S. Patent any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEEE Standards docum

3、ents are developed within IEEE Societies and Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. IEEE develops its standards through a consensus development process, which brings together volunteers representing varied viewpoints and interests to achieve th

4、e final product. Volunteers are not necessarily members of IEEE and serve without compensation. While IEEE administers the process and establishes rules to promote fairness in the consensus development process, IEEE does not independently evaluate, test, or verify the accuracy of any of the informat

5、ion contained in its standards. Use of IEEE Standards documents is wholly voluntary. IEEE documents are made available for use subject to important notices and legal disclaimers (see http:/standards.ieee.org/IPR/disclaimers.html for more information). IEC collaborates closely with IEEE in accordance

6、 with conditions determined by agreement between the two organizations. 2) The formal decisions of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC Nationa

7、l Committees. The formal decisions of IEEE on technical matters, once consensus within IEEE Societies and Standards Coordinating Committees has been reached, is determined by a balanced ballot of materially interested parties who indicate interest in reviewing the proposed standard. Final approval o

8、f the IEEE standards document is given by the IEEE Standards Association (IEEE-SA) Standards Board. 3) IEC/IEEE Publications have the form of recommendations for international use and are accepted by IEC National Committees/IEEE Societies in that sense. While all reasonable efforts are made to ensur

9、e that the technical content of IEC/IEEE Publications is accurate, IEC or IEEE cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications (inc

10、luding IEC/IEEE Publications) transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC/IEEE Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC and IEEE do not provide any

11、attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC and IEEE are not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the l

12、atest edition of this publication. 7) No liability shall attach to IEC or IEEE or their directors, employees, servants or agents including individual experts and members of technical committees and IEC National Committees, or volunteers of IEEE Societies and the Standards Coordinating Committees of

13、the IEEE Standards Association (IEEE-SA) Standards Board, for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC/IEEE Publicatio

14、n or any other IEC or IEEE Publications. 8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that implementation of this IEC/IEEE Pub

15、lication may require use of material covered by patent rights. By publication of this standard, no position is taken with respect to the existence or validity of any patent rights in connection therewith. IEC or IEEE shall not be held responsible for identifying Essential Patent Claims for which a l

16、icense may be required, for conducting inquiries into the legal validity or scope of Patent Claims or determining whether any licensing terms or conditions provided in connection with submission of a Letter of Assurance, if any, or in any licensing agreements are reasonable or non-discriminatory. Us

17、ers of this standard are expressly advised that determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility. ,( design models; design implementation descriptions; verification coordinators, stimulus generators, checkers and as

21、Glossary of Terms there are three kinds of answers: a/o/n (a/o/n, Always, Often, Never), y/n (y/n, y, n), or empty for free text. The tool uses this attribute to propose the possible answer values for the assessment of the criterium. g127 The element class specifies the class of the criterium; there

22、 are four classes: Imperative, Rule, Guideline, or Optional. The tool uses this attribute to classify the criterium. g127 The element weight specifies the integer score of the criterium when satisfied. The tool uses this attribute for scoring and consolidation. g127 The element dependent specifies t

23、he integer id of another criterium from which the current criterium depends. If the referenced criterium is not satisfied then the current criterium is not relevant. The tool uses this attribute to identify the parent of the criterium. Figure 6 Criterium element 5.1.1.1 Example The following example

33、ling requirements for operating on golden XML The golden XML file contains the complete list of quality criteria (or questions) classified by topic and assessment type. The XML elements criterium, topic, and assessment contain attributes and subelements, used to store the relevant data and informati

34、on to enable automation of the QIP management with tools. The golden XML can be downloaded from the online IEEE repository.11The tool shall read and parse the golden XML file, check the semantic of the imported XML file with the golden XML schema, and translate the XML structure in a proprietary dat

35、a structure format. The golden XML schema file is accessible from the online IEEE repository.12If an error is detected during the golden XML file import, the tool shall display an explicit message with the detailed information for debugging and stop the import operation without creating or updating

36、its internal data structure. By way of example, an error shall be generated if a wrong value is supplied for a field subType. See Figure 9 for an example of a means for displaying this information. 11Available at http:/standards.ieee.org/downloads/1734/1734-2011/ieee-qip-golden.xml. 12Available at h

The tool shall interpret the different XML elements and att

39、ributes as described in 4.3.1. The tool shall operate on the QIP criteria following the rules described in the Annex B. 5.3.1 QIP checklist table construction using the golden XML The top level element of the golden XML file holds the version number of the golden XML file and the URL for XML schemas

40、. The tool shall use the attributes xmlns:* to search for the golden XML schema. The tool should store the float attribute version in its internal data structure to later check the coherence with imported answer XML files version. Example: 5.3.2 Assessments The second level elements of the golden XM

41、L file represent the highest level topical areas of the QIP: the types of assessment. These are: Vendor, Soft IP Integration, Soft IP Development, Hard IP Integration, Hard IP Development, Verification IP, Software IP. Example: . 17 Copyright 2011 IEEE. All rights reserved.

The

43、text attribute title shall be used by the tool to display the title of the assessment table. 5.3.3 Top level topics The third level elements of the golden XML file represent the top level topical areas of the QIP assessment. These are: Vendor Assessment, IP Ease of Reuse, Design & Verification Quali

44、ty. Example: The tool shall create a specific section for each third level element of the golden XML, within the assessment table. The attribute qipId shall be used by the tool to form and display a unique name for the section header row. The text attribute title shall be used by the tool to display

45、 the title of the top level topical area in the header row of the corresponding section. The float attribute order shall be used by the tool to display the different top level topical areas in the proper order. 5.3.4 Topics The fourth level elements of the golden XML file represent the topical areas

46、 within the top level topical areas of the QIP assessment. These are for example: Configurability and Parameterization, Build Environment, Portability Issues, and others. Example: The tool shall create a specific section for each fourth level element of the golden XML, within the parent top level to

47、pical area sections of the assessment table. The attribute qipId shall be used by the tool to form and display a unique name for the section header row. The text attribute title shall be used by the tool to display the title of the topical area in the header row of the corresponding section. The flo

48、at attribute order shall be used by the tool to display the different topical areas in the proper order. 5.3.5 Questions The fifth level elements of the golden XML file represent either the final topical sub-areas or questions (criterium elements). The sixth level elements of the golden XML file, if any, represent questions (criterium elements). The criterium elements are the leaves of the tree structure. Example: 18 Copyright 2011 IEEE.
