Strategies for Removing Common Mode Failures from TMR Designs Deployed on SRAM FPGAs

Triple modular redundancy (TMR) with repair has proven to be an effective strategy for mitigating the effects of single-event upsets within the configuration memory of static random access memory field-programmable gate arrays. Applying TMR to the design successfully reduces the design's neutron cross section by 80×. The effectiveness of TMR, however, is limited by the presence of single bits in t...
