15、Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed quality. The object of the System is to facilitate international trade by the harmonization of the specifications and quality assessment procedures for electronic components,
16、 and by the grant of an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System are thereby acceptable in all member countries without further testing. This specification has been formally approved by the CECC, and has been prepared for those countrie
17、s taking part in the System who wish to issue national harmonized specifications for DIGITAL GATE ARRAY INTEGRATED CIRCUITS. It should be read in conjunction with the current regulations for theCECC System. At the date of printing of this specification, the member countries of the CECC are Austria,
18、Belgium, Denmark, Finland, France, Germany, Ireland, Italy, theNetherlands, Norway, Portugal, Spain, Sweden, Switzerland and theUnitedKingdom, and copies of it can be obtained from the addresses shown on the blue fly sheet. Preface This blank detail specification (BDS) was prepared byCECCWG9:“INTEGR
19、ATED CIRCUITS”. It is based, wherever possible, on the Publications of the International Electrotechnical Commission and in particular on IEC747: Semiconductor devices Discrete devices and integrated circuits, and IEC748: Semiconductor devices Integrated circuits. The text of this specification was
20、circulated to the CECC for voting in the documents listed below and was approved for publication: It is recognized that the layout proposed cannot be applied to all detail specifications based on this document. For instance, it may be preferable to indicate the limiting values in the form of a table
21、 when several similar devices appear in the same detail specification. AVIS In accordance with the decision of the CECC Management Committee, this specification is published initially in English and French. The German text will follow as soon as it has been prepared.

This is necessary, because it is related to non-finished products, where the
23、customer is involved in their design, layout and specification. As a consequence, this BDS describes requirements for “tools” (e.g.fordesign, verification, test, and measurement), rather than requirements for components. The application of this specification requires that the relevant process techno
24、logy and the associated manufacturing line are already qualified. The following information is given for guidance. Scope This BDS relates to Integrated Gate Arrays in accordance with IEC748: Semiconductor devices Integrated circuits. A gate array is a circuit having a design methodology based on a t
25、echnological process and function library which elements have been prediffused. The set of such gate arrays shall be defined in terms of complexity: maximum number of equivalent gates maximum percentage of usable gates (where appropriate) die size I/O number.
