This specification defines a standard XML format for representing electronic design intellectual property (IP) quality information, based on an information model for IP quality measurement. It includes a schema and the terms that are relevant for measuring IP quality, including the software that executes on the system. The schema and information model can be focused to represent particular categories of interest to IP users. In the context of this document, the term IP shall be used to mean electronic design intellectual property. Electronic design intellectual property is a term used in the electronic design community to refer to a reusable collection of design specifications that represent the behavior, properties, and/or representation of the design in various media.

This guide assists users in specifying the functional requirements for transmission static Var compensators (SVCs) using conventional thyristor technology. Many sections will be useful for compensator systems using gate turn-off thyristor technology [static synchronous compensator (STATCOM)] or other semiconductor devices, or SVCs associated with high-voltage direct current (HVDC) converter stations, or industrial and distribution applications. Although this guide may not directly serve for… read more SVCs primarily associated with industrial drives nor with the correction of load disturbances or phase unbalance, many sections will be useful also for these applications. General terms and conditions forming the commercial part of a specification for a particular project are outside the scope of this document. read less

This guide establishes typical dimensions for connections of a gas insulated substation (GIS) to extruded, self contained fluid-filled, and high pressure fluid-filled (pipe-type) cables in single and three phase arrangements for voltages 72.5 kV and above. The guide applies to both fluid filled and dry type cable terminations with insulating barrier separating SF6 gas in GIS housing from the termination fluid. It also determines the arrangement for dielectric tests of the termination with simulated GIS enclosure. Responsibilities in grounding connections, installation, and field tests are also defined.

This document is a guide for field testing and commissioning of static var compensators (SVCs). As such, the document establishes general guidelines and criteria for field testing to verify the specified performance of SVC systems. Many clauses will be useful for compensator systems using gate turn-off (GTO) thyristor technology (static compensator [STATCOM]) or other semiconductor devices such as insulated gate commutated transistor (IGCT). This guide does not a) Cover factory and simulator… read more tests of SVC system components (but it assumes that such tests have been performed beforehand). b) Discuss the division of responsibility between user and supplier, since this division is usually defined in the contract between buyer and supplier. Most often, however, the practice is for the equipment, subsystem, and commissioning tests to be performed by the supplier, and the acceptance tests to be performed by the buyer or user. read less

This standard defines a low-cost method for testing the interconnection of discrete, complex memory integrated circuits (ICs) where additional pins for testing are not available and implementing boundary scan (IEEE Std 1149.1)1 is not feasible. This standard describes the implementation rules for the test logic and test mode access/exit methods in compliant ICs. The standard is limited to the behavioral description of the implementation and will not include the technical design for the test… read more logic or test mode control circuitry. read less

This standard details the criteria required for communication between a C12.21 Device and a C12.21 Client via a modem connected to the switched telephone network. The C12.21 Client could be a laptop or portable computer, a master station system, or some other electronic communications device. This standard does not specify the implementation requirements of the telephone switched network to the modem, nor does it include definitions for the establishment of the communication channel. This document provides details for an implementation of the Open Systems Interconnection (OSI) seven-layer model in accordance with ISO/IEC 7498-1. The protocol specified in this standard was designed to transport data in Table format. The Table definitions are in ANSI C12.19 and in Annex D of this document. This standard specifies the differences between ANSI C12.18-2006 and ANSI C12.19-1997 and the features and services required to describe a protocol specification for telephone modem communications.
