Background
The application software running in the processing unit of the nuclear power plant is high-safety software, and the designer of the application software is often nuclear power engineering related personnel rather than software developers. From the perspective of convenience, usability and efficiency of use of designers, or from the perspective of high security requirements of application software, the generation of application software codes first requires the design and development of a logic configuration function diagram to be completed.

The logic configuration function diagram has complex flow and various functions. The logic configuration function diagram is crucial in the whole life cycle of the application software from design to use. The functional diagram is used in subsequent V & V, test, joint debugging and other links. Participants in each link need to understand the idea of the designer and the logical meaning to be expressed by the logic diagram.
For complex logic diagrams, a large amount of description information is included outside the core logic, which needs to be passed to the next link in a stepwise, accurate and dependent manner. Therefore, in the prior art, it is very difficult to accurately transmit the design information of the engineering designer to the subsequent links only by using the logic function diagram.

On one hand, the method can realize that the description information in the whole logic function diagram is transferred to the next link step by step, accurately and dependently; on the other hand, the logic part of the functional diagram is guaranteed not to be interfered and influenced.
The invention provides a method for layering graph drawing according to grades and an algorithm for automatic area tracking closing. The core logic function and the description information are all presented by the same logic function diagram, and the presentation mode of the description information is flexibly designed by designers according to actual requirements. The main work to be done to implement the present invention consists of four steps. Firstly, according to user setting, a logic layer and a cloud layer drawn by a graph are flexibly switched. Secondly, according to the input of an operator, a cloud picture frame pattern is set, and the thinking activities of the operator are shown by different line widths, colors, line types and the like. And thirdly, according to the position of a plurality of points selected by a user on the cloud picture labeling layer, the configuration software searches for a track according to a rectangular algorithm and a Bezier curve algorithm, completes the area closing, and draws the cloud picture. And finally, when the function graph is converted into the code, the configuration software filters the cloud layer, and converts the logic layer into the logic code, so that the cloud layer is not influenced by the operation logic.
