The invention discloses an FPGA (
Field Programmable Gate Array) single-particle overturning
soft error detection method based on redundancy
interconnection resources. The FPGA single-particle overturning
soft error detection method comprises the following steps: step 1, establishing a connection relation in
interconnection resources in an FPGA; step 2, not using a logic unit and directly inserting a comparing circuit into an FPGA device; step 3, finding a
copying line for the existing
interconnection resources; and step 4, combining the
copying line and the comparing circuit to carry out dual
backup comparison on the FPGA based on the redundancy interconnection resources so as to realize error detection. By the aid of the FPGA single-particle overturning
soft error detection method, a phenomenon that more redundancy exists in the interconnection resources of the design is sufficiently designed, and an efficient redundancy interconnection resource
search algorithm is explored; an FPGA structure is simply modified so that the efficient online detection on single-particle overturning soft errors is realized.
