Fault filling method and apparatus based on programmable logical device

Abstract

The present invention provides a fault injection method based on programmable logic device and its device. Its kernel lies in that a fault injection module is set in the interior of programmable logic device having need of making fault injection to obtain the signal of the described programmable logic device, the described fault injection module can inject the correspondent fault into the obtained signal and can output the signal in which the fault is injected. Said invention has no need of external fault injection equipment or scrambling equipment, and can utilize the fault injection module set in the interior of programmable logic device to make fault injection process have no need of manual intervention and do not damage the programmable logic device.

Description

technical field [0001] The invention relates to electronic equipment, in particular to a fault injection method and device based on programmable logic devices. Background technique [0002] With the development of testing technology, fault-tolerant testing has been paid more and more attention. [0003] The purpose of fault-tolerant testing is to determine the impact of faults on the system and the ability of the system to automatically return to normal after the fault is restored. [0004] Therefore, generating the fault signal required for fault-tolerance testing is a very necessary step in the process of fault-tolerance testing. [0005] Fault injection technology is a technology gradually developed to meet the needs of fault-tolerant testing. [0006] Due to the advantages of powerful programmable performance, high-speed processing speed, and numerous pins in today's electronic product design, programmable logic devices are widely used in clock generation, synchronizat...
