Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawings and examples.

[0032] The working principle of the automotive software source code simulation test system based on the UPPAAL model is as follows: figure 1 shown. Requirements specification document can be formalized as UPPAAL model, and UPPAAL model can be used to verify requirements and generate software source code. In order to realize the automation and real-time performance of the source code simulation test system, it is necessary to convert the UPPAAL model into C++ code. The input of the source code simulation test system is a queue of triples (d, e, t), where d is a collection of data variables, e is a collection of event variables, and t is a collection of clock constraints. An input tuple (d, e, t) indicates that when the data input is d and the clock constraint is t, the event request message e is sent. When the software source code and the converted UPPAAL mo...

Abstract

The invention belongs to the field of software engineering and designs an automobile software source code simulation test system aiming to solve the problems existing in a source code test related to a controllable physical working process in an automobile software system, according to features of a UPPAAL model. The input of the system is a triple queue composed of a data variable set, an event variable set and a clock constrained set, and the output of the system is the data variable set. In order to achieve automaticity and real-time property of the source code simulation test system, the UPPAAL model is converted into a C++code. All input data are processed by a software source code and the UPPAAL model after code conversion, and if output results are consistent, a source code can be judged to be correct, otherwise, mistakes are judged to exist. By the aid of an automobile software source code simulation test method based on the UPPAAL model, the source code related to the controllable physical working process in an automobile software can be tested, and accordingly safety of the system is guaranteed, software development cost can be lowered, software development speed is accelerated, and quality of softwares is improved.

Description

technical field [0001] The invention relates to the field of software engineering, in particular to a method for simulating and testing automobile software source codes based on the UPPAAL model. Background technique [0002] With the continuous improvement of automobile intelligence, more control functions tend to be realized by software, resulting in the continuous growth of the scale and complexity of automobile software. Manfred Broy predicted in the literature [M.Broy, I.H.Kruger, A.Pretschner, C.Salzmann.Engineering Automotive Software.Proceedings of the IEEE,95(2):356-373,2007.], "the In the next generation of high-end cars, the total amount of software will reach 1GB, software will become the main contributor to the value of the car, and the proportion and cost of software development will continue to increase.” With the continuous increase of the proportion of software in automobiles, automotive software development is facing more and more challenges. These challen...
