Abstract

The present invention discloses a model based system design and information flow visualization simulation system and method. The system comprises a component model library module, a system model building module, an information display module, a simulation code generation module, a code compiling module, and a running and control module. The present invention by integrating a model concept into a software development process, provides a novel software development and test method, and the method improves a conventional software development mode, and improves development efficiency; based on a reusable component model, the present invention adopts a building block manner to build a system model, so that the amount of manually written codes is reduced to a large extent, the work focus of a developer is shifted to the logic and principle design, and programmable ability of the system is lifted; and the present invention adopts a simulation information visualization manner to display a program running process and delivery variable information, and the conventional black box test is turned to be a white box test, so that validation capability of system design is improved.

Description

technical field [0001] The invention belongs to the field of software development and simulation, in particular to a model-based system design and information flow visualization simulation system and method. Background technique [0002] With the rapid development of computer technology and the continuous improvement of human needs, the functions of software are becoming more and more complex, and the requirements for software security and stability are becoming increasingly strict. The competition in the market and the individual needs of different customers shorten the software development cycle continuously, which puts forward strict requirements for software development and testing. At present, software development mainly includes three stages: requirement analysis, software development and software testing. In the software development stage, a large amount of source code needs to be written. However, the traditional manual coding method is not only time-consuming and l...

AI Technical Summary

Problems solved by technology

In the software development stage, a large amount of source code needs to be written. However, the traditional manual coding method is not only time-consuming and labor-intensive, but also the reliability of the code cannot be guaranteed. Developers need to devote a lot of energy to boring code writing instead of software architecture design. and logic design, which greatly reduces the efficiency of software development

[0003] At present, the way to improve the efficiency of the development stage is to use code reuse technology and automatic code generation technology. The existing code reuse and automatic code generation technology has a high threshold for use, and it is difficult for non-professionals to operate and requires a lot of manual configuration and use. intervene

In the system testing stage, the current situation is that almost all system integration tests are black-box tests (that is, only know whether the output results are correct, but do not know anything about the running path of the code), and the program cannot be directly obtained during the test The running path of the program, and it is impossible to directly obtain some information during the running process of the program

Therefore, once the test results do not meet the expected value, it will take a lot of time to determine the location of the error, which greatly increases the time required to fix software defects

At the same time, since the traditional test can only measure whether the result is correct, it is impossible to distinguish the situation where the running path is wrong but the result happens to be correct, which will bury hidden dangers for the correctness of the software.

In addition, the separation of software development environment and test environment also increases the time cost of software development
