| Abstract | Two 65 nm bulk complementary metal-oxide-semiconductor (CMOS) digital application-specific integrated circuit (ASIC) chips were designed, and then tested in a heavy ion accelerator to characterize single-event effects (SEE). Test chip 1 incorporates test structures, and test chip 2 implements an unhardened and a hardened digital signal processing (DSP) core. Our testing results reveal the radiation effects on the low-voltage and high-frequency operations of the ASIC chips. At a low supply voltage of 0.7 V, cross sections increase by a factor of 2 to 5 at low linear energy transfer (LET), while the increase in cross section at high LET is almost negligible, suggesting that the charge conveyed by heavy ion has far exceeded the critical charge and tuning the supply voltage is not effective. Increasing the clock frequency increases the relative importance of single-event transients (SET) compared to single-event upsets (SEU), especially in hardened designs due to their better SEU immunity. The hardened DSP core experiences a factor of 2 increase in cross section when its clock frequency is increased from 100 MHz to 500 MHz. |

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.
