| Abstract | Escaped errors in released silicon are growing in number due to the increasing complexity of modern processor designs and shrinking production schedules. Worsening the problem are recent trends towards chip multiprocessors (CMPs) with complex and sometimes non-deterministic memory subsystems prone to subtle, devastating bugs. This deteriorating situation is causing a growing portion of the validation effort to shift to post-silicon, when the first few hardware prototypes become available and where validation experiments are run directly on newly manufactured prototype hardware. While post-silicon validation enables much higher raw performance in test execution, it is a much more challenging environment for bug diagnosis and correction. In this work we briefly overview some of the current methodologies used in industry. We then discuss some recent ideas developed in our research group to leverage the performance advantage of post-silicon validation, while sidestepping its limitations of low internal node observability and expensive bug fixing. Finally we present some of today's general trends in post-silicon validation research. |

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.
