Abstract

The invention discloses a method and system for reliability testing of a software and hardware system. The method includes: obtaining a comprehensive test profile of the software and hardware system; obtaining the conversion sequence of each working mode corresponding to the temperature step of the comprehensive test profile; The working status, task category and proportional factor of the mode switching sequence; generate the comprehensive probability of each working mode switching sequence, normalize the comprehensive probability, and generate the execution times of each working mode switching sequence; according to the preset test cycle times and each The number of execution times of the working mode conversion sequence is generated to test the sequence for software reliability testing. The implementation of the present invention enables the reliability test to more accurately simulate actual use conditions, truly reflect the adaptability of the software and hardware system to operational changes and environmental changes during actual use, and detect comprehensive software and hardware failures that may occur in actual use.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of reliability testing, in particular to a method and system for reliability testing of software and hardware systems. [0003] 【Background technique】 [0004] With the improvement of the intelligence of the equipment system, more and more functions are realized by software. Most of the equipment systems are inseparable from the software system. Algorithms and functions originally implemented by hardware, such as DSP algorithms, have gradually become software Combined with hardware to achieve, some functions have even been realized by pure software. Therefore, the probability of software defects leading to system failure is also increasing. A multi-task software-hardware system (hereinafter referred to as a "software-intensive system") composed of hardware embedded with software is characterized by a high degree of integration of hardware and software. [0005] However, the reliability testing of s...
