IEC 63501-2416:2023

Overview

IEC 63501-2416:2023 (also published as IEEE Std 2416) defines a parameterized, abstracted power modeling framework to enable accurate system-level power, software, and hardware IP-centric analysis and optimization. Published as an IEC–IEEE double-logo standard (Edition 1.0, 2023-10), it describes concepts and requirements for building power models that are efficient, complete, and portable across process, voltage, and temperature (PVT) conditions. The standard targets system-level power/thermal analysis by specifying the information content and architecture needed for reusable power models.

Key topics and requirements

• Parameterized power models: Guidance for workload and architecture parameterization so models represent a range of operating scenarios.
• PVT independence: Concepts to decouple models from specific process, voltage, and temperature points for broader applicability.
• Power & thermal management interface: Definitions for how models expose control and telemetry for system-level power and thermal management.
• Model architecture: Two modeling levels and four modeling representations are defined to support different abstraction layers.
• Library and cell semantics: Formal semantics for libraries, cells, pins, modes, events, states, and contributors to ensure consistent model interpretation.
• Power contributors and energy contributors: Structured constructs to represent dynamic and static power sources within IP blocks and subsystems.
• Data structures and expressions: Table formats, indices, expression types, and parameter expressions to capture model data efficiently.
• Information-content requirements: Minimum content and organization recommendations to guide development and interoperation with other modeling standards.

Applications and who should use it

IEC 63501-2416 is practical for organizations and roles involved in system-level power/thermal optimization:

• System architects and SoC designers who need system-level power budgets and tradeoffs.
• IP vendors and hardware designers creating reusable power models for integration into larger systems.
• EDA and tools vendors implementing power modeling, simulation, and analysis flows.
• Power/thermal management engineers who require standardized interfaces for control and telemetry.
• Software and firmware teams optimizing runtime behavior against power/thermal constraints.

Typical applications include SoC power estimation, thermal management validation, workload-aware power optimization, IP power characterization, and integration of multiple IP power models into a system simulation.
