|Abstract||Self-assembled nanofabrication processes yield regular and reconfigurable devices. However, defect densities in this emerging nanotechnology are higher than those in conventional lithography-based VLSI. In this article, we present an application-independent defect tolerant design flow to minimize customized postfabrication design efforts to be performed per chip. In this flow, higher level design steps are not needed to be aware of the existence and the location of defects in the chip. Only a final mapping step is required to be defect aware. Application independence of this flow minimizes the number of per-chip design steps, making it appropriate for high volume production. We also present two mapping algorithms, recursive and greedy, which make the connection between defect-unaware design steps and the final defect-aware mapping step. Experiments show that the results obtained by the greedy algorithm are very close to the exact solutions. Using these algorithms, we analyze the manufacturing yield of molecular crossbars under different defect distribution models. We report on the size of the minimum crossbar to be fabricated such that a defect-free crossbar of the desirable size can be found with a guaranteed manufacturing yield.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at 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 Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
