151015Abstract: The IP-XACT Standard forms the conformance checks for XML data designed to describe electronic systems. The meta data forms which are standardized include: components, systems, bus interfaces and connections, abstractions of those buses, and details of the componentsincluding address maps, register and field descriptions, and file set descriptions for use in automating design, verification, documentation, and use flows for electronic systems. The standard includesa set of XML schemas of the form described by the World Wide Web Consortium (W3C) and a setof semantic consistency rules (SCRs). The standard also provides for a generator interface that isportable across tool environments. The specified combination of methodology-independent metadata and the tool-independent mechanism for accessing that data provides for portability of designdata, design methodologies and environment implementations.Keywords: Electronic Design Automation, EDA, XML Design Meta Data, IP-XACT, XML Schema,Tight Generator Interface, TGI, Semantic Consistency Rules, SRCs, Design Environment, UseModels, Tool And Data Interoperability, Implementation Constraints, Register Transfer Logic, RTL,Electronic System Level, ESL, Bus Definitions, Abstraction Definitions, and Address Space Specification.202530354045The SPIRIT Consortium.1370 Trancas Street #184, Napa, CA 94558Copyright 2007 - 2008 by the SPIRIT Consortium.All rights reserved.

IP-XACT meta-data and tool interfacesIP-XACT Standard/D4, December 19, 20071IntroductionThis introduction is not part of the Draft Standard for the IP-XACT meta-data and tool interfaces.5The purpose of this standard is to provide the electronic design automation (EDA), semiconductor,electronic intellectual property (IP) provider, and system design communities with a well-defined andunified specification for the meta-data which represents the components and designs within an electronicsystem. The goal of this specification is to enable delivery of compatible IP descriptions from multiple IPvendors; better enable importing and exporting complex IP bundles to, from and between EDA tools forSoC design (system on a chip design environments); better express configurable IP by using IP meta-data;and better enable provision of EDA vendor-neutral IP creation and configuration scripts (generators). Thedata and data access specification is designed to coexist and enhance the hardware description languages(HDLs) presently used by designers while providing capabilities lacking in those languages.The SPIRIT Consortium is a consortium of electronic system, IP provider, semiconductor, and EDAcompanies. IP-XACT enables a productivity boost in design, transfer, validation, documentation, and use ofelectronic IP and covers components, designs, interfaces, and details thereof. It is extensible in specifiedlocations.IP-XACT enables the use of a unified structure for the meta specification of a design, the components that isbased on manual or automatic methodologies. IP-XACT specifies the tight generator interface (TGI) foraccess to the data in a vendor-independent manner.This standardization project provides electronic design engineers with a well-defined standard that meetstheir requirements in structured design and validation and enables a step function increase in theirproductivity. This standardization project will also provide the EDA industry with a standard to which theycan adhere and which they can support in order to deliver their solutions in this area.The SPIRIT Consortium has prepared a set of bus and abstraction definitions for several common buses. It isexpected, over time, that those standards groups and manufacturers who define buses will include IP-XACTXML bus and abstraction definitions in their set of deliverable. Until that time, and to cover existing usefulbuses, a set of bus and abstraction definitions for common buses has been created.101520253035A set of reference bus and abstraction definitions allows many vendors who define IP using these buses toeasily interconnect IP together. The SPIRIT Consortium posts these for use by its members, with nowarranty of suitability, but in the hope that these will be useful. The SPIRIT Consortium will, from time-totime, update these files and if a Standards body wishes to take over the work of definition, will transfer thatwork to that body.40These reference bus and abstraction definition templates (with comments and examples) are available fromthe public area of the http://www.spiritconsortium.org web site.45Notice to users50ErrataErrata, if any, for this and all other standards of The SPIRIT Consortium can be accessed at the followingURL: http://www.spiritconsortium.org/releases/errata/.
