IEC 61523-1:2012

Delay and power calculation standards - Part 1: Integrated circuit delay and power calculation systems

IEC 61523-1:2012(E) focuses on delay and power calculation for integrated circuit design with support for modeling logical behavior and signal integrity. This second edition cancels and replaces the first edition, published in 2001, and constitutes a technical revision.

Overview

IEC 61523-1:2012 - Delay and power calculation standards, Part 1 - specifies requirements for integrated circuit delay and power calculation systems used in IC design. This second edition (2012) is a technical revision that cancels and replaces the first edition (2001). The standard provides guidance and a framework for IC timing and power analysis with explicit support for modeling logical behavior and signal integrity, and is published in close alignment with IEEE Std 1481-2009.

Key Topics

• Scope of delay and power calculation systems: Defines the intended use and functional boundaries for tools that perform delay estimation and power calculation in integrated circuit design flows.
• Modeling logical behavior: Requirements for representing logic functionality so that delay and power estimations reflect realistic switching and functional scenarios.
• Signal integrity support: Consideration of crosstalk, coupling and interconnect effects to improve accuracy of delay and power analysis.
• Tool-level interoperability: Guidance to help ensure consistent results across EDA tools and calculation engines (interfaces, inputs and outputs implied by tool-system requirements).
• Technical revision highlights: Updates from the 2001 edition that reflect advances in analysis methods, device scaling and signal-integrity-aware modeling.

Applications

IEC 61523-1:2012 is practical for organizations and professionals involved in:

• IC design and verification - architects and design engineers using delay and power estimation as part of timing sign-off and power budgeting.
• EDA tool vendors - developers of static timing analysis, power-estimation, and signoff tools who need to align features with an international standard.
• Semiconductor teams - validation, characterization and IP integration groups requiring repeatable, standardized delay and power calculation practices.
• System integrators - ensuring IC-level power and timing estimates propagate accurately into board- and system-level planning. Practical uses include early-stage power budgeting, timing closure workflows, signal-integrity-aware timing checks, and harmonizing results from multiple calculation tools.

Who Should Use It

• IC design houses and semiconductor companies
• Electronic design automation (EDA) vendors
• Verification and signoff engineers
• IP integrators and system architects

Related Standards

• IEEE Std 1481-2009 - explicitly referenced and co-published alignment in the IEC document header.
• Other parts of the IEC 61523 series (Part 1 is focused on integrated-circuit systems) - consult IEC catalog for updates and related parts.

By adopting IEC 61523-1:2012, teams can improve the consistency and reliability of integrated circuit delay and power calculation, especially where logical behavior modeling and signal integrity materially affect timing and power outcomes.
