IEC/IEEE Dual Logo International Standards This Dual Logo International Standard is the result of an agreement between the IEC and the Institute of El
13、ectrical and Electronics Engineers, Inc. (IEEE). The original IEEE Standard was submitted to the IEC for consideration under the agreement, and the resulting IEC/IEEE Dual Logo International Standard has been published in accordance with the ISO/IEC Directives. IEEE Standards documents are developed
14、 within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus development process, approved by the American National Standards Institute, which brings together volunteers represent
15、ing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve without compensation. While the IEEE administers the process and establishes rules to promote fairness in the consensus development process, the IEEE does not independe
16、ntly evaluate, test, or verify the accuracy of any of the information contained in its standards. Use of an IEC/IEEE Dual Logo International Standard is wholly voluntary. The IEC and IEEE disclaim liability for any personal injury, property or other damage, of any nature whatsoever, whether special,
17、 indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance upon this, or any other IEC or IEEE Standard document. The IEC and IEEE do not warrant or represent the accuracy or content of the material contained herein, and expressly disclaim a

19、EEE Dual Logo International Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEC/IEEE Dual Logo International Standard. Furthermore, the viewpoint expressed at the time a standard is appr
20、oved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is more than five years old and has no
21、t been reaffirmed, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. In publishing and making this document available, the

Interpretations Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific applic
24、ations. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of concerned interests, it is important to ensure that any interpretation has also received the concurrence o
25、f a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration. Comments for revision of
26、IEC/IEEE Dual Logo International Standards are welcome from any interested party, regardless of membership affiliation with the IEC or IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Comments on standards a

IEEE introduction The IEEE 1076.1 language, informally known as VHDL-AMS, is a superset of IEEE Std 1076-2002 (VHDL) that provides capabili
36、ties for describing and simulating analog and mixed-signal systems with conservative and nonconservative semantics for the analog portion of the system. The language supports many abstraction levels in electrical and non electrical energy domains. The modeled analog systems arelumped systems that ca
37、n be described by ordinary differential equations and algebraic equations. The language does not specify any particular technique to solve the equations, but it rather defines the results that must be achieved. The solution of the equations may include discontinuities. Interaction between the digita
38、l part of a model and its analog part is supported in a flexible and efficient manner. Finally, support for frequency domain small-signal and noise simulation is provided. The extension of VHDL to support analog and mixed-signal systems began in 1989, as part of the second revision of IEEE Std 1076
39、targeted for a 1993 release. A large number of requirements to support analog and mixed-signal systems were submitted, and it soon became apparent that the complexity of the topic required the formation of a separate working group. The design of the IEEE 1076.1 language formally began in 1993, when
40、the IEEE 1076.1 Working Group was formed under the auspices of the Design Automation Standards Committee of the IEEE Computer Society, under Project Authorization Request (PAR) 1076.1. Its charter was to extend the IEEE 1076 (VHDL) language to support the requirements for the description and simulat
41、ion of analog and mixed-signal systems. The IEEE 1076.1 Working Group approved the draft standard in June 1997. The first release of the draft of IEEE Std 1076.1-1999 was approved by the IEEE Standards Board on 18 March 1999. The 2007 revision includes changes made to IEEE Std 1076-2002 since the fi
42、rst release of the IEEE 1076.1 standard. It also includes clarification of IEEE 1076.1 language definitions and corrections of typographical errors that were introduced in the 1999 version of the IEEE 1076.1 language reference manual. See the Annex D for a list of changes from the 1999 release. Noti
