| Abstract | This paper presents new techniques for generating a small set of patterns for power network simulation to estimate the maximum power supply noise of the chip, as well as to identify cells/blocks for which the power supply noise at their V/sub dd/ ports exceeds a specified threshold. We first present an efficient, cell-level simulator for estimating power supply noise of any given vectors. Based on this simulator, we then apply the genetic algorithm (GA) to derive a small set of patterns producing high power supply noise. To identify critical nodes with power supply noise exceeding a threshold, the multiobjective GA is adapted for pattern generation. To achieve high coverage of such critical nodes, we model the search criteria as the maximum weighted matching of a bipartite graph, and guide the search direction according to the matching results. The derived patterns will be simulated on a power network simulator to obtain a lower bound of the maximum power supply noise and to identify the critical nodes. Experimental results on public benchmark circuits, as well as some industrial designs, are presented to demonstrate the efficiency and effectiveness of the proposed approaches. |

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.
