    24、 CORE MODEL OF THE ELECTRONICS DOMAIN FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all quest

    25、ions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(

    26、s)”). Their preparation is entrusted to technical committees; 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. IEC colla

    27、borates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion o

    28、n the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure

    29、 that the technical content of IEC Publications is accurate, IEC 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 transparently to t

    30、he maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered res

    31、ponsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its techn

    32、ical committees and IEC National Committees 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 Publication or any other IEC

    33、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 some of the elements of this IEC Publication may be the subjec

    34、t of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62016 has been prepared by IEC technical committee 93: Design automation. The document was released by the feeder organization, Government Electronics and Information Techn

    35、ology Association, a sector of the Electronic Industries Alliance (EIA), for committee draft, comment, and review by members of IEC TC93 1. The text of this standard is based on the following documents: FDIS Report on voting 93/172/FDIS 93/176/RVD Full information on the voting for the approval of t

    36、his standard can be found in the report on voting indicated in the above table. _ 1The EIA feeder organization retains the copyright and intellectual property of this work but provides permission for IEC to reproduce and exploit the information contained herein. 6 62016 IEC:2003(E) This standard doe

    37、s not follow the rules for the structure of International Standards given in the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until 2012-07. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised editio

    38、n, or amended. 62016 IEC:2003(E) 7 INTRODUCTION The Core Model of the electronics domain provides a common basis for design information handled by CAD systems within the electronic domain. It is the purpose of this model to provide a conceptual representation of the electronics domain, so that the c

    39、ompliant CAD systems handle a similar set of concepts, thus making inter-communication, sharing and exchange of design information a much easier task. It is not the purpose of this model to describe implementation details or to provide a data representation of electronics domain information. The Cor

    40、e Model of the electronics domain, Edition 1.0, is referred to as the “Core Model” throughout this document. The Core Model, in part, has been created by enhancing the industry connectivity consensus model, EDIF CFI DR Alignment Model Version 1.0 (www.edif.org). The chosen description language for t

    41、his Core Model is EXPRESS, as defined by ISO 10303-11. It is necessary to describe the Core Model as an information model in order to provide a formal definition of the design information that shall be be recognized by the compliant CAD systems. The benefits of a formal description derive from its a

    42、bility to provide an unambiguous representation of concepts, attributes and relationships, and the global rules and constraints that may be applied. By having such a description, it is possible to check the consistency and the correctness of the model as well as to provide a reliable starting-point

    43、for further development. It also facilitates the design of correct electronics CAD implementations based on this Core Model, as the actual implementation methods can be checked against the model. This Core Model includes connectivity, hierarchy and design information for the electronics domain. Futu

    44、re parts of this Core Model standard may be extended to include other categories of information (for example, cell_representation, schematic representation, the PCB domain, symbols and display information). In order to facilitate the creation of other parts of this Core Model standard, some objects

    45、have been used in this Core Model to facilitate support for other parts of the electronics domain. There are two types of such objects. Entities, such as cell_representation, are important concepts that provide support for defining other Core Model parts. Constraints: Some of constraints of this Cor

    46、e Model use conditions that are always true. They have been written in this way in order to ensure that they remain valid when the model is extended. 8 62016 IEC:2003(E) CORE MODEL OF THE ELECTRONICS DOMAIN 1 Scope and object This International Standard provides the semantics definitions for the fol

    47、lowing categories of information related to electronic circuit designs. Each category of design information is modelled as an EXPRESS schema. The Core Model consists of 10 schemas. Each of them is presented in this document as a separate chapter. At the beginning of each chapter, a description of th

    48、e corresponding schema is provided. The hierarchy_model schema describes the hierarchical information of a cell, i.e. the way a cell may be divided into other cells. A circuit may be divided into cells which, in turn, may be further subdivided into other cells, thus creating a hierarchy. The hierarc

    49、hy information describes the cells, the possible cell representations and their instances. The design_hierarchy_model schema describes the annotation on an occurrence hierarchy. The definition of a design requires that specific representations (views) of design objects in the hierarchy are selected. This unambiguously creates a configured design hierarchy. This concept is similar to the configuration of a design in VHDL and is related to view selection mech
