Abstract | Circuit fingerprinting is a method that adds unique features into each copy of a circuit such that they can be identified for the purpose of tracing intellectual property (IP) piracy. It is challenging to develop effective fingerprinting techniques because each copy of the IP must be made different, which increases the design and manufacturing cost. In this paper, we explore the Observability Don't Care (ODC) conditions to create multiple fingerprinting copies of a design IP (e.g. in the form of gate level layout) with minute changes. More specifically, we find locations in the given circuit layout where we can replace a gate with another gate and some wires without changing the functionality of the circuit. However, as expected, this could introduce design overhead. Our experimental results show that, although we can embed fingerprints of up to 1438 bits, there is an average of 10.9% area increase, 50.5% delay increase, and 9.4% power increase on circuits in the MCNC and ISCAS 85 benchmark suites. We further propose a fingerprinting heuristics under delay constraints to help us reduce area and power overhead. |

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.
