What is IP-XACT?
IP-XACT is the IEEE 1685 standard for describing semiconductor IP, interfaces, registers, memory maps, connectivity, and system architecture using a machine-readable format. It provides a common framework for capturing design metadata that can be shared across tools and engineering teams, enabling automation, interoperability, and reuse throughout the SoC development lifecycle.
Why does IP-XACT matter?
As modern SoCs grow in complexity, engineering teams must manage hundreds of IP blocks, multiple processor architectures, extensive software stacks, and increasingly sophisticated integration requirements. Manual processes create inefficiencies, inconsistencies, and opportunities for error. IP-XACT addresses these challenges by providing a standardized way to describe and exchange design information across the development flow.
What does IP-XACT describe?
IP-XACT can capture a wide range of design information, including:
- IP blocks and reusable design components
- Interfaces and bus protocols
- Registers and memory maps
- Address spaces and bridges
- Configuration parameters and design variants
- System hierarchy and assembly information
How IP-XACT works
IP-XACT uses XML-based descriptions to define the structure and relationships of design elements. EDA tools, integration platforms, software development environments, and documentation systems can consume these standardized descriptions. Rather than recreating information in multiple formats, engineering teams can establish a single source of truth that remains consistent across the project lifecycle.
The role of IP-XACT in SoC integration
IP-XACT has become one of the foundational standards for SoC integration and design automation. Standardizing how IP and system information are described enables automation of tasks such as IP packaging, interface validation, register generation, system assembly, and documentation creation. This reduces manual effort while improving consistency and reuse across projects.
IP-XACT and the digital thread
One of the most significant advantages of IP-XACT is its ability to establish a digital thread across hardware and software development. The same metadata can be leveraged by architects, design engineers, verification teams, software developers, and documentation groups. This improves traceability, reduces duplication of effort, and helps maintain consistency throughout development.
IP-XACT and Magillem
Magillem has been one of the industry’s leading contributors to the adoption and practical application of IP-XACT. For more than two decades, semiconductor companies have used Magillem solutions to automate IP packaging, connectivity management, register generation, documentation, and system assembly using IP-XACT as the underlying data model.
Today, Magillem solutions from Arteris continue to build upon this standards-based foundation, helping engineering organizations establish a digital thread that connects IP creation, integration, verification, software development, and documentation. By leveraging industry-standard metadata rather than proprietary formats, teams can improve reuse, reduce integration effort, and maintain consistency across increasingly complex SoC programs.

Frequently asked questions
What does IP-XACT stand for?
IP-XACT originally stood for “Intellectual Property eXtensible Markup Language-based description format,” although it is now most commonly referenced as IEEE 1685.
Is IP-XACT an IEEE standard?
Yes. IP-XACT is standardized as IEEE 1685 and is widely adopted throughout the semiconductor industry.
Why is IP-XACT important for SoC development?
It provides a standardized way to describe IP and system metadata, enabling automation, consistency, interoperability, and reuse across the design flow.
How does IP-XACT improve IP reuse?
The IP-XACT standardizes the description of interfaces, registers, parameters, and connectivity, making it easier to reuse IP across multiple projects.
Is IP-XACT still relevant?
Yes. As SoCs evolve to include chiplets, heterogeneous compute architectures, and larger software ecosystems, standardized metadata has become increasingly important for integration and automation.
How does Magillem use IP-XACT?
Magillem solutions use IP-XACT as the foundation for integration automation, connectivity management, register generation, packaging, documentation workflows, and system assembly.
