Abstract | Characterization of I/O channels in 3D package systems is quite challenging as it is difficult to observe signal quality. A traditional way of measuring each device in a component level does not capture complex interaction in 3D integration. Although a sense line can be designed to externally measure noise on power lines, it is not feasible for signal lines as it significantly alters the signal quality. Hence, on-chip measurement features are highly desirable for 3D package systems including emerging Through-Silicon Vias (TSV) technology. In this paper, four key on-chip measurement concepts and circuitries are reviewed: eScope for measuring overall link margins, eWave for capturing a signal waveform, nScope for generating and monitoring on-chip power noise, and zScope for measuring power distribution network (PDN). These circuitries are implemented in a low power differential memory interface. The test vehicle is built based on Package-on-Package (PoP) environment. Measurements from the test vehicle are compared with the predicted data based on simulation. |

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.
