Problems solved by technology

The traditional repair method adopts three-mode redundant backup, and directly switches to a brand new circuit when a failure occurs; although this method works well, it may start the entire backup system due to a small error, using too much circuit resources
[0003] Due to the characteristics of application scenarios such as aviation, aerospace, navigation, weapons, etc., it is impossible to manually input all possible error information in advance

Abstract

The invention discloses a circuit self-repairing method based on improved evolution hardware. The circuit self-repairing method comprises the following steps: realizing a self-repairing circuit by adopting the evolution hardware; a compensation circuit is additionally arranged on a circuit system, error output is repaired, a truth table of the compensation system is obtained by performing exclusive-or operation on target output and error output by utilizing the characteristic of reverse calculation of the exclusive-or operation, and after the compensation system is realized, the function of repairing the error output is completed by utilizing the exclusive-or operation. According to the invention, the self-repairing circuit of evolved hardware is used for repairing an error part only, circuit resources are reduced, and the reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of reliability embedded system design, in particular to a circuit self-repair method based on improved evolution hardware. Background technique [0002] For aviation, aerospace, navigation, weapons and other application scenarios, the operation of the circuit is difficult to be subject to human intervention. Once the circuit fails, the ability to self-repair the circuit is required. The traditional repair method uses three-mode redundant backup, and directly switches to a brand-new circuit in the event of a failure; although this method works well, it may start the entire backup system due to a slight error, and it is used too much. circuit resources. [0003] Due to the characteristics of application scenarios such as aviation, aerospace, navigation, and weapons, it is impossible to manually input all possible error information in advance. The self-evolution characteristics of the evolutionary hardware p...
