A joint reliability test profile construction method for a hybrid system of software and hardware

Abstract

The invention discloses a joint reliability test section construction method for a software and hardware hybrid system. The method comprises a total of 12 steps: the software and hardware hybrid system is analyzed; a comprehensive task section of the software and hardware hybrid system is determined; a hardware task section is determined; an environment section is determined; an electromagnetic section is determined; a hardware reliability test section is determined; a software task section is determined; a software-related function section is determined; a software-related operation section is determined; a software reliability test section is determined; probabilistic scenario information is determined; and the hardware reliability test section and the software reliability test section are combined. The influences of electromagnetic interference stress on the hardware and software hybrid system can be considered, the actual use situation of the software and hardware hybrid system canbe more truly reflected, and the reliability test of the software and hardware hybrid system based on the reliability test section detects the software and hardware hybrid system comprehensive faultappearing during the actual use process, and reliability identification test of the software and hardware hybrid system is more facilitated.

Description

technical field [0001] The invention relates to the field of reliability test of a software-hardware hybrid system, in particular to a joint reliability test profile construction method of a software-hardware hybrid system, which is suitable for the reliability design of a software-hardware hybrid system. Background technique [0002] With the development of modern electronic technology, information technology, especially embedded technology, and software-hardware collaborative design technology, more and more weapons and equipment are designed using a hybrid method of software and hardware based on general-purpose or special-purpose computing platforms. Increasing digitization and automation have dramatically increased the size and complexity of equipment. The traditional method of reliability test of mixed hardware and software system is to test the reliability of the hardware and software parts respectively. When assessing and testing the software part, the influence of t...

Problems solved by technology

Today's human living environment already has a strong electromagnetic environment, and the electromagnetic environment in which products are located is becoming more and more complex. The electronic system of the hybrid hardware and software system itself is also becoming more and more complex. The defects of the hardware hybrid system may not be found, which is not conducive to the improvement of the reliability of the hardware and software hybrid system

Currently, there is a lack of implementation of targeted test profiles in the reliability identification and acceptance tests of mixed hardware and software systems. To explore the method of comprehensive test profiles for the reliability of mixed hardware and software systems can meet the urgent needs of reliability tests for mixed hardware and software systems.
