Embodiment Construction
[0027] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be further described in detail and in-depth with reference to the accompanying drawings and examples below.
[0028] A reliability comprehensive test profile construction method combining software and hardware proposed by the present invention includes a hardware reliability profile and a software reliability profile, and an effective combination between the two, wherein the combination method of the two is to combine these two types of profiles Slice and combine slices based on the combination of tasks and time.
[0029] Since the construction method of the hardware reliability profile is very mature, the hardware reliability profile in the present invention is mainly drawn according to the reliability identification and acceptance test standard GJB899A-2009, and the appendix B of this standard describes in detail the determination of t...

The invention provides a constitution method of comprehensive reliability testing profile for both software and hardware. The method is used for reliability testing of an embedded system and includes the steps of system analysis, system task analysis, system flow analysis, core profile constitution, probabilistic information determining and software-hardware reliability profile combining. A hardware reliability profile and a software reliability profile are constituted and are sectioned, sections are combined on the basis of a task combing point and a time combining point, and accordingly the profiles are effectively combined. By the constitution method, true service condition of the embedded system can be truly embodied, reliability test data of the tested embedded system, which is generated on the basis of the comprehensive test profiles, is more reliable and more adaptable to reliability testing of systems, and the constitution method can be used for failure analysis for the tested embedded systems.
Description
technical field [0001] The invention is applied to the field of reliability testing of embedded systems, and specifically relates to a method for constructing a reliability comprehensive test profile combining software and hardware. Background technique [0002] With the application of embedded systems more and more widely in various fields, the reliability and security of the system have higher requirements. Due to the close combination of software and hardware, the reliability of an embedded system depends on its software and hardware. However, at present, software and hardware reliability tests are usually carried out separately, and the corresponding test profiles are also considered separately. Even if the software and hardware comprehensive test is carried out together, the constructed software and hardware reliability test profile does not consider consistency from the perspective of the system, and the failure data collected on this basis cannot be used for system r...
