Title: On-Line Single Event Upset Detection and Correction in Field Programmable Gate Array Configuration Memories
Abstract: Larger field programmable gate array (FPGA) configuration memories and shrinking design rules have raised concerns about single event upsets (SEUs), especially for highreliability, high-availability systems that use FPGAs. We present a design for the on-line detection and correction of SEUs in the configuration memory of Xilinx Virtex-4 and Virtex-5 FPGAs. The design corrects all single-bit errors and detects all double-bit errors in the configuration memory at maximum speed and with minimal overhead and power dissipation. A method for SEU emulation in the configuration memory of FPGAs is presented which enables the experimental verification of the approach. The results of SEU emulation in Xilinx FPGAs are discussed. 1
