IEEE 1481-2019

IEEE 1481-2019 is the IEEE standard for Integrated Circuit (IC) Open Library Architecture (OLA) - Redline, providing a technical reference for how IC library structures are organized and reviewed. It is relevant to components, circuits, devices, and systems work where consistent library architecture supports clearer design exchange and evaluation. IEEE 1481-2019 helps teams compare requirements, track changes, and understand the architecture rules that shape IC library development and maintenance.

IEEE 1481-2019 overview

This standard focuses on the open library architecture used in integrated circuit design environments, with the redline format highlighting changes relative to a prior edition. IEEE 1481-2019 is useful when engineering teams need a controlled view of library structure, interface expectations, and related documentation for IC assets. In practice, it supports more reliable interpretation of the architecture so that design data can be handled consistently across development, review, and procurement workflows.

Typical use cases

IEEE 1481-2019 is commonly used in IC design and verification workflows where library organization affects how components are specified, shared, and maintained. It may support teams working with design databases, library management tools, and engineering documentation for semiconductor devices and related systems. The standard can also be useful during internal reviews, supplier coordination, and change tracking when a redline document is needed to identify updates in the open library architecture.

Why this standard matters

Clear library architecture reduces confusion when multiple engineers, tools, or organizations must work from the same IC design reference. IEEE 1481-2019 supports consistency in how requirements are understood and applied, which can improve design control and lower the risk of mismatched interpretations. For organizations handling component-level technical data, the redline format is especially practical because it makes revisions easier to inspect, helping with compliance review, documentation management, and controlled adoption of changes.
