Abstract

The growing adoption of SRAM-based FieldProgrammable Gate Arrays (FPGAs) in safety-criticalapplications demands for efficient methodologies forevaluating their reliability. Single Event Upsets (SEUs)affecting the configuration memory of SRAM-basedFPGAs are a major concern, since they can permanentlyaffect the function implemented by the device. Weexploited a fault-injection environment developed at ourinstitution to analyze the impact of such faults on SRAM-basedFPGAs when fault tolerant design techniques areadopted. The experimental results allow quantitativeevaluations of the effects of these faults, and show that thesensitivity of the TMR design technique mainly dependson the characteristics of the adopted TMR architecture interms of placing and routing.
