A sram type fpga flipping fault injector and fault injection method

Abstract

The invention provides an SRAM type FPGA turnover fault injection device and fault injection method. An upper computer indicates a lower computer to perform chain device identification, thereby obtaining a device type corresponding to an ID of a target FPGA device; the upper computer selects a working interface and indicates the lower computer to perform configuration bit stream backward reading through the working interface; an original configuration bit stream file of the target FPGA device is obtained; the upper computer indicates the lower computer to finish power-on program loading of thetarget FPGA device by utilizing the original configuration bit stream file of the target FPGA device; the upper computer generates a turnover fault injection bit stream file according to a fault injection type; and the lower computer is indicated to finish fault injection for the target FPGA device through the selected working interface by utilizing the fault injection bit stream file. The shortcomings that an existing hardware fault injection device is complex and high in cost, a test result after injection is low in credibility because an existing fault model for software fault injection isinsufficiently real, and the like can be overcome.

Description

technical field [0001] The invention relates, in particular, to an SRAM (Static RAM, static random access memory) type FPGA (FieldProgrammable Gate Array, field programmable gate array) flip fault injector and a fault injection method. Background technique [0002] Single event effects mainly include SEU (Single Event Upset, single event flip), SET (Single Event Transient, single event transient pulse), SEL (Single Event Latch, single event lock), etc., among which SEU is the most important form of expression. For SRAM-type FPGAs, single-event effect failures, especially single-event flipping failures, are very likely to occur due to the SRAM process used. From the perspective of the proportion of single event flip failures, configuration memory accounts for the largest proportion, followed by LUT-type RAM, block RAM and flip-flops, and other (such as SET, SEFI) single event effect failures account for a smaller proportion , the SEU of the configuration memory is the most i...
