| Abstract | The on board control, signal acquisition and communication (OBCSAC) subsystem is a critical component of all satellite systems. This paper presents the results of a feasibility study on realizing the design subsystem first on FPGA, and then on ASIC. Apart from giving the design details and results on a typical basic configuration, a number of extensions of this architecture have been studied and the results are presented. Specifically, starting from the realization of the basic configuration on a commercial antifuse FPGA, the studies carried out include (a) mapping the vital configuration onto an equivalent radiation hardened antifuse FPGA (b) mapping the same configuration onto a commercial FPGA after incorporating dasiaTriple Modular Redundancy (TMR) manually at the RTL level, (c) altering the basic architecture significantly to conform to the CCSDS standard prescribed for the OBCSAC of any satellite and mapping the design onto to FPGAs as well as on ASICS first without TMR and then separately incorporating TMR for each case. The basic configuration realized in an FPGA had been extensively tested in hardware under various expected environmental conditions and the FPGA utilization details are provided. For the ASIC design, the details up to the layout/GDSII stage are presented. Further, in the case of the ASIC, the test patterns for the netlist were generated based on ATPG software and the details of fault coverage are provided. The FPGA designs were carried out with Actel SX72A and AX1000 device families and the ASIC designs were carried out using the AMIS 0.35u CMOS libraries. The results presented in this work will serve as a design guideline in terms of FPGA/ASIC area, power, speed, and fault coverage and fault tolerance to those working in the area of system design. |

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.
