| Abstract | This paper introduces a new methodology for digital design properties extraction from simulation traces. The innovated methodology is based on a new data mining technique guided with static analysis of the intended design. The mining engine of the proposed methodology is based on innovated Breadth-First Decision Tree (BF-DT) search algorithm. The data structure of each node in the decision tree is handled to well present sub-space of the input simulation traces data space. Besides, new features are added to BF-DT to enhance its performance in both output sequential assertions and time of search. A new static analysis technique is innovated to extract all the combinational and sequential data dependencies between the digital design signals. The mining engine is guided with these data dependencies to extract complete combinational and sequential design properties relating signals desired to extract properties for and their cone of interest signals. The contributed mining technique has been tested for bit-level designs with different sizes. The design properties generated from the mining engine completely match with all design properties covered in the input simulation traces. Plus, the generated properties are at the highest possible level of abstraction leading to the best coverage for the input data space. The simulation results show that the proposed methodology has proven superior efficiency in extracting bit-level assertions of digital design in a feasible time. The next challenge is to include word-level assertions as well. |

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.
