| Abstract | We introduce a detailed process for software requirements safety analysis. The approach for identification of safety faults in this process is based on fault tree analysis. This process consists of four main steps: software requirements fault tree generation; software requirements fault tree verification and validation; software safety requirements generation and safety fault mitigation; and software requirements safety verification and validation. We have defined a set of rules that can automatically generate the software requirements fault tree given the software requirements specified in Statemate, and the software fault tree top events identified in the system safety analysis. Statemate CASE tool is used in this process for specification of software requirements, and execution and analysis of the software requirements to verify and validate safety. Essential tree analysis is introduced as a method for dependency analysis of the software fault tree top event. The outcome of essential tree analysis is captured in an essential tree which we introduce as a graphical representation of the dependencies and their interrelations. |

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.
