| Abstract | Embedded systems are a key enabling technology for the recent vast increase in functionality of a huge list of critical infrastructures. Hybrid automata can be used to model system-level behaviors for the large category of systems that exhibit strong couplings between discrete and continuous dynamics. Many software tools have been developed for hybrid automata to enable model-based design of embedded systems and these software tools are constructed by using their own modeling languages. Model-based design frameworks, such as model-integrated computing (MIC), model driven architecture (MDA), and model driven design (MDD), have been advocated to raise the level of abstraction in software tool design by placing stronger emphasis on the use of software models in the software tool design process. In particular, MIC places strong emphasis on the use of domain specific modeling languages (DSMLs) and model transformations in design flows. Practical and effective development of formal specifications for DSML semantics within model-based tools can be challenging, but could positively impact adoption and reuse of these tools. The semantic anchoring methodology was developed to address this challenge by formally tying DSMLs to a "semantic unit", which is a formal specification that captures the operational semantics of a specific model of computation. Leveraging our prior work with semantic units, we develop a semantic unit for hybrid automata. In this paper, we explicitly specify the operational semantics of hybrid automata, and develop the corresponding semantic unit and model transformation rules. We demonstrate the effectiveness of the infrastructure in a practical case study involving the hybrid automata DSMLs, HyVisual and ReachLab. |

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.
