Problems solved by technology

However, these models have less support for AADL-based model testing, and these models are relatively deficient in describing the time attributes of the system, which cannot meet the testing requirements of embedded real-time systems.
The real-time and correctness of the embedded real-time system are the first issues to be considered in system design. If the execution of an embedded real-time system cannot meet the real-time response and correctness of operation, it will lead to disastrous consequences.

Embodiment Construction

[0030] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0031] This example describes the control system, the system consists of two process components, each process component contains three thread components, and each thread is a periodic thread. The system includes 5 modes os1, os2, 01, 02, 03, 04. After the system is initialized, it enters modal os1, which contains two modals 01 and 02. When the event ports t1s.e1 and t2s.e2 of threads t1 and t2 receive events, the trigger thread mode switches from 01 to 02. After the data port t3s.e3 of thread t3 receives an event, the thread mode switches from 02 to 01. The system mode os2 contains two modes 03 and 04. After the process p1 receives an event at the event port p1s.event1, it triggers the system mode transition from os1 to mode os2. Under the mode os2, the ports of threads t4 and t5 When t4s.e4 and t5s.e5 receive an event, they switch from mode 03 to mode 04, and...

Abstract

The invention relates to an embedded software testing method based on an AADL (Architecture Analysis and Design Language) mode time automata model, which is technically characterized by comprising the steps of: generating an AADL system member tree with mode information according to an AADL architecture model file, and constructing a time automata model of an AADL model through carrying out breadth-first traversal on the member tree. The correctness and the time attribute of converting the AADL model mode are verified by using a verifying tool of the traditional time automata. The method provided by the invention is used for testing the model in an early state of designing the embedded software so as to find whether the correctness and the real time of the software model meet the design requirement or not as soon as possible and immediately correct the design scheme, thereby shorting the period of developing the embedded real-time system and saving the development cost.

Description

technical field [0001] The invention relates to an embedded software testing method based on an AADL modal time automaton model, and relates to an embedded system software testing method. Background technique [0002] With the growth of embedded software scale, various problems in the software development process are highlighted. Traditional software development processes such as V model and W model have been difficult to meet the needs of today's large-scale software development. To this end, the industry has proposed a model-driven architecture method (Model Driven Architecture, MDA), based on which a platform-specific system model constructed can be automatically converted into code. Therefore, the system model becomes the key to the software development process, and how to evaluate the quality of the model naturally becomes the key to the model-driven architecture software development. Traditional code-based software evaluation can no longer meet the evaluation needs of...
