Wide range of digital systems from wireless devices to multi-media terminals is characterized by their multi-mode behavior. Many of these systems are deployed in high-radiation environments. SRAM-based FPGAs are popular platforms to implement multi-mode systems, because of their high performance and reconfigurability. However, high susceptibility of FPGAs toward soft errors makes them less-than reliable platforms. To overcome the reliability issue, various redundancy techniques have been proposed. These techniques exhibit different design and the reliability characteristics.
