Embodiment Construction
[0020] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0021] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "front", "rear", "circumferential" and...

The invention relates to the technical field of radiation effect evaluation, and discloses a mobile terminal soft fault test method and system, and the method comprises the steps: enabling a to-be-tested mobile terminal to be in a test mode; performing an irradiation test on the to-be-tested mobile terminal by using a neutron beam; controlling the mobile terminal to be tested to operate different application functions; monitoring the to-be-tested mobile terminal, and observing and counting error conditions when the to-be-tested mobile terminal operates different application functions; and distinguishing different soft fault types according to the error condition. And the neutron beam is used to simulate irradiation of atmospheric neutrons on the mobile terminal to be tested in a real environment. And error conditions of the to-be-tested mobile terminal in different operation modes are observed and counted, and different soft fault types are distinguished based on the error conditions of the to-be-tested mobile terminal. An irradiation test is carried out on the to-be-tested mobile terminal through the high-flux neutron source, soft fault types possibly existing in the to-be-tested mobile terminal are rapidly excited, and effective data support is provided for product research and development personnel.
Description
technical field [0001] The invention relates to the technical field of radiation effect evaluation, in particular to a mobile terminal soft fault testing method and system. Background technique [0002] In the environment of our daily life, there is an invisible and intangible dangerous particle—atmospheric neutrons, which originate from the interaction between high-energy cosmic rays and the earth's atmosphere. Atmospheric neutrons are extremely penetrating and widely distributed on the ground and throughout the atmospheric space. The single event effect caused by the bombardment of atmospheric neutrons on semiconductor devices and integrated circuits may cause problems such as data flips, function errors, crashes, and even catastrophic burnouts of the devices. The processor and memory chip in the mobile phone system are sensitive components of atmospheric neutron single event effects, and are also the root cause of soft failures in the system. Random atmospheric neutrons...
