XML
Extensible Markup Language (XML) is a markup language and file format for storing, transmitting, and reconstructing arbitrary data. It defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. T ...
format that defines and describes individual, re-usable
electronic circuit designs (individual pieces of intellectual property, or IPs) to facilitate their use in creating
integrated circuits
An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material, usually silicon. Large numbers of tin ...
(i.e. ''microchips''). IP-XACT was created by the
SPIRIT Consortium as a standard to enable automated configuration and integration through tools.
The goals of the standard are
* to ensure delivery of compatible component descriptions from multiple component vendors,
* to enable exchanging complex component libraries between
electronic design automation (EDA) tools for
SoC design (design environments),
* to describe configurable components using
metadata, and
* to enable the provision of EDA vendor-neutral scripts for component creation and configuration (generators, configurators).

Overview
All documents will have the following basic titular attributes spirit:vendor, spirit:library, spirit:name, spirit:version.
A document typically represents one of:
* bus specification, giving its signals and protocol etc.;
* leaf IP block data sheet;
* or a hierarchic component wiring diagram that describes a sub-system by connecting up or abstracting other components made up of spirit:componentInstance and spirit:interconnection elements.
For each port of a component there will be a spirit:busInterface element in the document. This may have a spirit:signalMap
that gives the mapping of the formal net names in the interface to the names used in a corresponding formal specification of the port.
A simple wiring tool will use the signal map to know which net on one interface to connect to which net on another instance
of the same formal port on another component.
There may be various versions of a component referenced in the document, each as a spirit:view element, relating to different versions of a design: typical levels are gate-level, RTL and TLM.
Each view typically contains a list of filenames as a spirit:fileSet that implement the design at that level of abstraction in appropriate language, like Verilog,
C++ or PSL.
Non-functional data present includes the programmer's view with a list of spirit:register declarations inside a spirit:memoryMap or spirit:addressBlock.
