Artigo de evento Analyzing the Influence of using Reconfiguration Memory Scrubber and Hardware Redundancy in a Radiation Hardened FPGA under Heavy Ions(2018-09-05) OLIVEIRA, A.B. DE; BENEVENUT,I F.; BENITES, L. A. C.; RODRIGUES, G. S.; KASTENSMIDT, F. L.; ADDED N.; AGUIAR, V. A. P.; MEDINA, N. H.; Marcilei Aparecida Guazzelli; DEBARGE, C.© 2018 IEEE.This work investigates the influence of using the built-in configuration memory scrubber and triple modular hardware redundancy in the cross section of a radiation-hardened SRAM-based FPGA from NanoXplore. Different designs versions are investigated under heavy ions for the occurrence of transient errors, failures, and timeouts. The calculated dynamic cross-sections are in agreement with the expected order of magnitude of radiation hardened SRAM-based FPGAs. Results show that the most reliable configuration is using DSPs for the operational logic and applying full design redundancy combined with scrubbing.
