We introduce a new hardware/software platform for testing SRAM-based FPGAs under heavy-ion and neutron beams, capable of tracing the bit-flips in the configuration memory back to the physical resources affected in the FPGA. The validation was performed using, for the first time, the neutron source at the RAL-ISIS facility. The ISIS beam features a 1/E spectrum, which is similar to the terrestrial one with an acceleration between 107 and 10(8) in the energy range 10-100 MeV. The results gathered on Xilinx SRAM-based FPGAs are discussed in terms of cross section and circuit-level modifications.

Abstract
We introduce a new hardware/software platform for testing SRAM-based FPGAs under heavy-ion and neutron beams, capable of tracing the bit-flips in the configuration memory back to the physical resources affected in the FPGA. The validation was performed using, for the first time, the neutron source at the RAL-ISIS facility. The ISIS beam features a 1/E spectrum, which is similar to the terrestrial one with an acceleration between 107 and 10(8) in the energy range 10-100 MeV. The results gathered on Xilinx SRAM-based FPGAs are discussed in terms of cross section and circuit-level modifications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
