| Abstract | This paper introduces a method to predict of the impact of packaging changes on microprocessor maximum operating frequency (Fmax). This is useful both in package technology selection and subsequent design optimization. The method uses power draw versus frequency and Fmax versus supply voltage data to enable time-domain circuit simulations using a resistive-acting dissipative core model instantiated within a field-solver-based model of the package. Measurements and simulations are carried out for an existing part that is packaged in a first, characterization package, in order to back out a theoretical intrinsic Fmax versus supply voltage curve for the package-free device. Subsequent circuit simulations using alternative package models can then be used to find the new Fmax for the device in a new package of interest that may not yet be fabricated. The method is useful for tasks such as predicting the outcome of reduced cost re-packaging of existing parts or estimating package effect on new similar parts in a family of parts. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
