Embodiment Construction

[0026] The present invention will be further described in detail below with reference to the drawings and specific embodiments of the specification.

[0027] Such as figure 1 As shown, a single-event soft error system-level propagation analysis method based on cellular automata, its steps are:

[0028] (1) Functional module division; analyze the hardware structure, interface characteristics and function realization logic of the system, and divide the system into functional modules. Each functional module is a sub-circuit system capable of completing independent tasks;

[0029] (2) Establish a cell space and construct a cellular automaton; regard the entire system as a cell space, and each functional module as one of the cells, select the appropriate neighbor relationship according to the connection relationship of the cells; determine the cell Coupling degree and propagation rules between cells; combining cell space, neighbor relations, propagation rules, etc., to determine the cell...

Abstract

A cellular automata-based single particle soft error system level propagation analysis method comprises the steps of (1) dividing function modules: analyzing the hardware structure, interface characteristic and function implementation logic of a system to divide the function modules of the system, wherein each function module is a sub circuit system capable of completing tasks independently; (2) establishing a cellular space, and building a cellular automata: taking the whole system as one cellular space, and each function module as one of the cells, and selecting an appropriate neighbor relation based on the connection relation of the cells; determining the coupling degree and transmission rule among the cells; determining the state evolution process of the cells; (3) performing propagation analysis: assuming that a single particle soft error occurs on a certain function module, which means that the corresponding cells join the fault disturbance, on the basis of the propagation rule, analyzing the propagation process and influence of the single particle soft error in the system. The cellular automata-based single particle soft error system level propagation analysis method has the advantages of simple principle, easy operation, low complexity, capability of improving the analysis method precision and the like.

Description

Technical field [0001] The present invention mainly relates to the field of electronic system reliability analysis, and specifically refers to a single-event soft error system-level propagation analysis method based on cellular automata. Background technique [0002] Electronic systems operating in a space radiation environment or a nuclear explosion environment are extremely susceptible to single event effects. Although single event effects occur in a certain part or module of the system, after a single event soft error occurs, the corresponding functional module There will be faults, and through the coupling and propagation of faults between the functional modules and other modules, the faults will spread to the output end, and there is a certain probability that the output error or function failure of the system will result. In the end, a single-event soft error will cause the entire system to fail. Therefore, it is necessary to analyze the propagation and diffusion process of...
