Construction Method of Script-Based Embedded Software Simulation and Testing Integrated Platform

Abstract

The present invention belongs to the automation test field, relates to the automation test technology aiming at aircraft airborne embedded software, and relates to a construction method of a script-based embedded software simulation and test integrated platform. Implementation of the construction method is based on configuration of a real-time processor and a main control computer. In the main control computer, test cases and simulation models are described by using test scripts, anomaly detection is also carried out, and the scripts which are tested to be correct are sent down to the real-time processor. In the real-time processor, simulation of external crosslinking devices and a test device of a to-be-tested device is implemented on basis of the scripts. The external crosslinking devices are simulated by the simulation model scripts, and the test device is simulated by the test case scripts. The simulation model scripts and the test case scripts are parsed by a real-time script interpreter, all simulation and test tasks are added to a task register and scheduling module, and finally interaction with the to-be-tested device is implemented through a bus driving module.

Description

technical field [0001] The invention belongs to the field of automatic testing, is aimed at the automatic testing technology of aircraft airborne embedded software, and relates to a construction method of a script-based integrated platform for embedded software simulation and testing. Background technique [0002] The increasing complexity of airborne embedded systems puts forward higher requirements on the quality of equipment software. In airborne equipment, complex tasks usually require multiple devices to interact and cooperate to complete. This requires the development unit to connect to other manufacturers' equipment for debugging during the development and testing process, resulting in a long resource coordination cycle and unguaranteed project progress. In order to solve this problem, many simulation tool platforms have appeared, such as Matlab, SCADE, Rhapsody and so on. With the help of such tools, developers can simulate external cross-linking equipment with sim...

AI Technical Summary

Problems solved by technology

[0004] However, the following problems still exist in the front line of research and development. First, the threshold for using traditional simulation tool platforms is high, and the cycle of model establishment and verification is long.

Second, when the traditional simulation tool platform is used for simulation, the entire modeling process needs to be completed, and the model library written in C / C++ language accumulated by other units cannot be reused

Third, due to the different technical solutions adopted in the current simulation and testing platform, the testing and simulation processes are isolated from each other, so that the test script can only obtain the operation information of the device under test, but cannot obtain the operation information of the simulation model cross-linked with it. Therefore, Unable to build test cases for complex scenarios, insufficient testing

In addition, since the test script cannot detect the state of the simulation model during the run

When the final test case fails, it is impossible to determine whether it is the problem of the simulation model or the problem of the device under test itself

[0005] To sum up, traditional simulation and testing platforms cannot meet the requirements of ease of use, reusability and testing comprehensiveness. Therefore, it is of great significance and urgency
