| Abstract | Many prior works have discussed the power grid design and optimization in the post-layout stage, when design change is inevitably expensive and difficult. In contrast, during the early stage of a development cycle, designers have more flexibility to improve the design quality. However, there are several fundamental challenges at early-stage when design database is NOT complete, including extraction, modeling and optimization. This paper tackles these fundamental issues of early-stage power grid design. The proposed methods have been silicon-validated on 32nm on-market chips and successfully applied to a 22nm design for its early stage power grid design. The findings from such practices reveal that, for sub-32nm chips, intrinsic on-die capacitance and power gate scheme may have more significant impact than expected on power integrity, and need to be well addressed at early stage. |

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.
