Investigation of the Xilinx SEM Core on a Zynq-Based Software-Defined Radio Under Proton Irradiation

Abstract

This paper presents the latest single event effects (SEE) test results of the Xilinx soft error mitigation (SEM) core under proton irradiation. The Xilinx SEM code is used on a software-defined radio which uses the Xilinx Zynq-7020 system on-chip. The SEM core is being tested under different conditions to validate its performance under proton irradiation. In this test, the SEE susceptibility and dependency of programmable logic (PL) utilization and different flux configurations are evaluated. The test results show good performance of the SEM core under low proton flux conditions with no impact of field programmable gate array (FPGA) resource allocation.
