| Abstract | This work proposes a new fault-tolerant method able to deal with open and shortcut circuit faults in SRAM-based FPGA routing connections. The bitflips provoked by upsets in the routing control memory cells are the major concern in SRAM-based FPGAs, since these memory cells represent the majority of the bits in the configuration bitstream. Even in an application hardened by triple modular redundancy (TMR), upsets in the routing bits still represent a major problem, due to the possibilities of short and open circuits that can happen in more than one redundant block of the TMR The idea presented in this paper is to create local redundancy in the routing, so that whenever the critical connection fails, the redundant one ensures a working connection by propagating the correct value. The proposed method is based on duplication of the internal critical connections. A detailed classification and test of each case solution is explained in this paper. Preliminary results show the efficiency of this method to reduce error due routing upsets. |

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.
