| Abstract | Describes using cascading of two existing tools: Hyperbook for source code analysis to facilitate software understanding, and PARAGON, for static analysis of safety-critical real-time systems. The goal is to provide an efficient and scalable toolset that minimizes human interaction during analysis. The toolset operates directly on source code without the need for the user to come up with initial or intermediate specification. Such a specification is constructed automatically during the analysis. The toolset is applicable to analysis of legacy software as well as to validation of new software. It is oriented towards exhaustive static analysis of software, without resorting to simulation. The source code together with the description of its architecture and environment are presented as input. Hyperbook produces a set of state machines that represent the static view of the code. The state machines serve as input to PARAGON. PARAGON reports interleaved events, which are used for software understanding and testing. It can detect flaws such as whether deadlocks are possible or if any catastrophic events may occur. PARAGON can produce diagnostic information that is used to identify the source of the problem. A major concern in software reengineering is the size of the source software. Hyperbook partitions the source code into software units that conform with the given architectural view. PARAGON's formal analysis is performed in a modular and hierarchical fashion. |

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.
