| Abstract | Soft errors caused by ionizing radiation have emerged as a major concern for current generation of CMOS technologies and the trend is expected to get worse. Soft error rate (SER) measurement, expressed as number of failures encountered per billion hours of device operation, is time consuming and involves significant test cost. The cost stems from having to connect a device-under-test to a tester for extended period of time. While built-in self-test (BIST) mechanisms have been around for over a decade, that minimizes the use of a tester; they have not been applied to measure or characterize soft error rate. This is because traditional BIST methods cannot distinguish between a soft failure and a hard failure and have no provision for counting the number of errors. In this paper, we propose a BIST design for soft error rate (SER) characterization, which obviates those issues. The proposed BIST based SER measurement scheme can be further accelerated by improved controllability and observability while unlike traditional BIST schemes, a test by test failure detection capability enables higher diagnostic resolution for single event based transient errors. We further propose to integrate this chip-level BIST-based SER characterization system with a distributed on-line scheme using a network controller that tests multiple chips in parallel and completely eliminates the need for a tester. The hardware overhead of the proposed architecture is small and it becomes insignificant for larger design. |

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.
