| Abstract | Thermal effects are becoming a limiting factor in high-performance circuit design due to the strong temperature-dependence of leakage power, circuit performance, IC package cost and reliability. While many interconnect reliability models assume a constant temperature, this paper presents a physics-based model for estimating interconnect lifetime for any time-varying temperature/current profile. This model is verified with numerical solutions. With this model, we show that designers may be more aggressive with the temperature profiles that are allowed on a chip. In fact, our model reveals that when the temperature magnitude variation is small, average temperature (instead of worst-case temperature) can be used to accurately predict interconnect lifetime, allowing for significant design margin reclamation in reliability-aware design. Even when the variation of temperature magnitude is large, our model shows that using the maximum temperature is still too conservative for interconnect lifetime prediction. Therefore, our model not only increases the accuracy of reliability estimates, but also enables designers to consider more aggressive designs. This model is similarly useful for temperature-aware dynamic runtime management. |

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.
