Abstract

The invention discloses a homemade computer based build in test system and method, which belong to the technical field of computer self-detection and achieve the effects that a build in test (BIT) function of a homemade computer is realized and the demands of a homemade computer platform on possession of fault detection and isolation capabilities and shortening of maintenance time are met. The technical scheme is that: the homemade computer based build in test system and method is provided; hardware involved in the system comprises a system-level testing module, a module-level testing module and a chip-level testing module; and software layers involved in the system include a hardware platform layer, a driver layer, a kernel layer, a support layer and an application layer. The homemade computer based build in test system and method adopts the self-detection system, performs self-detection on the homemade computer, and comprises power-on BIT, periodic BIT and maintenance BIT.

Description

technical field [0001] The invention relates to the technical field of computer self-testing, in particular to a system and method based on domestic computer self-testing. Background technique [0002] With the increasing complexity and technical content of computers, maintainability and testability have an increasingly important impact on the combat capability, survivability, mobility, maintenance personnel, and support costs of computer equipment. In the prior art, the connotation of testability mainly uses automatic test equipment (ATE). [0003] ATE is the abbreviation of Automatic Test Equipment, which is translated as automatic test equipment, which is used to test the integrity of the integrated circuit function of the computer, and is the final process of integrated circuit manufacturing to ensure the quality of integrated circuit manufacturing. In the manufacturing process of all electronic components (Device), there is a need to remove the false and preserve the t...
