Study on Testing and Harden Technique of Single Event Upset for SRAM-Based FPGA

With the increasing application of SRAM-based FPGA,only the specially designed testing program according to its features can obtain the accurate characteristics of single-event upset,which may supply the basis for strengthening anti-radiation.The static and dynamic methods for testing single event upset were described in detail.In static testing,the hardware and readback program of the test system were designed.In the dynamic testing,the corresponding software testing programs were designed for CLB and BRAM.Some efficient methods from engineering application were given to improve the reliability of field programmable gate array.The testing obtained the upset cross sections,which are very important for evaluating the reliability of FPGA on the ground.
