5、 Standards documents are developed within the Technical Committees of the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Board. Members of the committees serve voluntarily and without compensation. They are not necessarily members of the Institute. The standards devel
6、oped within IEEE represent a consensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE that have expressed an interest in partici- pating in the development of the standard. Use of an IEEE Standard is wholly voluntary. The existence of an IEEE S
7、tandard does not imply that there are no other ways to produce, test, measure, purchase, mar- ket, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about thro
8、ugh developments in the state of the art and com- ments received from users of the standard. Every IEEE Standard is subjected to review at least every ve years for revision or reafrmation. When a document is more than ve years old and has not been reafrmed, it is reasonable to conclude that its cont
9、ents, although still of some value, do not wholly reect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership afliation wi
10、th IEEE. Suggestions for changes in docu- ments should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specic applications. When the need for
11、 interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appro- priate responses. Since IEEE Standards represent a consensus of all concerned inter- ests, it is important to ensure that any interpretation has also received the concurrence of a balance of in
12、terests. For this reason IEEE and the members of its technical com- mittees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration. Comments on standards and requests for interpretations should be add

This package provides a
16、 standard datatype system for the declaration of ports and signals used in modeling digital components in VHDL. Use of this package with its dened logic values and operators is intended to provide a mechanism for writing VHDL component models that have well-dened behavior when connected to other mod
17、els adhering to this standard. Development of the Std_logic_1164 package: The work of this committee is the culmination of efforts by several groups with the same goals working over a period of over three years. The EIA (Electronic Industries Association) and the VDEG (VHDL Design Exchange Group) ha
18、ve been working on the problem of interoperable VHDL component models since the standardization of VHDL by the IEEE in 1987. The work at the EIA has been guided by John Wilner, Jack Kinn, and Len Finegold in their efforts to produce a specication for procuring interoperable VHDL compo- nent models.
19、The work at the VDEG was guided by Moe Shahdad, Ghulam Nurie, and its last chair, Victor Berman, who merged this group with the IEEE Model Standards Group in order to promote a unied stan- dard. The VDEG group has since disbanded. At present there is agreement by the IEEE P1164 and EIA 567 groups on
20、 this standard. Between 1989 and this date, many individuals made valuable contributions to the development of this stan- dard. At the time of approval of the standard, the members of the working group were: William Billowitch, Chair David AckleyAndrew GuylerZainalabedin Navabi Gordon AdsheadWilliam
