Abstract

The invention provides an aviation application-based verification method for domestic storages. The aviation application-based verification method sequentially comprises the following steps: 1) storage chip detection; 2) board level functionality test; 3) board level performance test; 4) complete machine level verification; 5) comprehensive analysis and evaluation. According to the aviation application-based verification method disclosed by the invention, basic environment adaptation verification is performed on the applications of the domestic storages on aviation weapon systems, and the single memory unit faults, single memory unit reversal faults, inter-unit coupling faults and memory faults and unit sensitization faults of the various storages, as well as the data retention faults of the changes of unit logical values due to electric leakage after some periods, can be verified, thus providing a beneficial guarantee for domestic development of the aviation weapon systems.

Description

technical field [0001] The invention belongs to the field of avionics circuit testing, and relates to a method for verifying the application of a localized memory based on aviation applications. Background technique [0002] With the increasingly urgent need for the localization of aviation weapons, as the core information carrier, the memory has many types and wide applications, and plays a pivotal role and position in the weapon system; Scientific research institutions have the research and development capabilities of domestic memory, but domestic memory generally has the characteristics of many types, late start, and low maturity. It lacks effective aviation adaptability testing methods before installation and use, and cannot be effectively used in the initial stage of model development. Therefore, it is urgent to explore a scientific and effective application verification method for localized storage in the aviation environment. Contents of the invention [0003] In o...
