SDF (Standard Delay Format) is an existing OVI standard for the representation and interpretation of timing data for use at any stage of the electronic design process. The ASCII data in the SDF file is represented in a tool and language independent way and includes path delays, timing constraint values, interconnect delays and high level technology parameters.

This part of ISO/IEC 15026 specifies the concept of integrity levels with corresponding integrity level requirements that are required to be met in order to show the achievement of the integrity level. It places requirements on and recommends methods for defining and using integrity levels and their integrity level requirements. It covers systems, software products, and their elements, as well as relevant external dependences.This part of ISO/IEC 15026 is applicable to systems and software and… read more is intended for use by:a) definers of integrity levels such as industry and professional organizations, standards organizations, and government agencies;b) users of integrity levels such as developers and maintainers, suppliers and acquirers, users, and assessors of systems or software and for the administrative and technical support of systems and/or software products.One important use of integrity levels is by suppliers and acquirers in agreements; for example, to aid in assuring safety, economic, or security characteristics of a delivered system or product.This part of ISO/IEC 15026 does not prescribe a specific set of integrity levels or their integrity level requirements. In addition, it does not prescribe the way in which integrity level use is integrated with the overall system or software engineering life cycle processes. It does, however, provide an example of use of this part of ISO/IEC 15026 in Annex A. read less

This recommended practice defines the processes and procedures that should be followed to implement Verification, Validation, and Accreditation (VV&A) for federations being developed using the High Level Architecture (HLA) Federation Development and Execution Process (FEDEP). This recommended practice is not intended to replace existing VV&A policies, procedures, and guidance, but rather is intended to focus on the unique aspects of the VV&A of federations. It provides a higher-… read more level framework into which such practices can be integrated and tailored for specific uses. The VV&A overlay provides implementation-level guidance to VV&A practitioners; however, it does not describe the individual techniques that might be employed to execute the VV&A processes for federations. This VV&A overlay focuses upon the VV&A processes that apply to federations and not the VV&A processes associated with individual simulations (federates), but does consider using the information produced by those processes. Users, developers, and VV&A personnel working with simulations and simulation compositions not based upon the HLA and the FEDEP can also benefit from the guidance in this document since the activities that this overlay describes can be tailored to support any type of distributed simulation application. read less

The peak-program meter (PPM) is designed for directly measuring the quasi-peak level of complex electrical audio signals occurring in the transmission or recording of an audio program in order to achieve optimum technical utilization of the transmission channel or recording medium. For this purpose, full-wave rectification is used, and the integration time is chosen to indicate the level of those peaks that would cause audible nonlinear distortion if they were clipped or otherwise severely… read more distorted by the transmission channel or recording medium. The PPM can therefore be used to indicate the peak level that the channel or medium must accommodate if audible distortion is to be avoided. This standard refers to the overall characteristic of the PPM and not the performance of its component parts. read less
