[0033] like Figure 1 As shown, an embodiment of the present invention provides a method for developing customized embedded software based on models and templates, comprising:

[0034] S101. According to the requirements analysis of the embedded software system program, a requirements model of the embedded software system to be developed is established, a design model is derived from the requirements model, and according to the test standard, unit test properties are set for the minimum processing unit in the design model to generate a unit test case model; based on the requirements model, a system test case model is created;

[0036] The model-based embedded software development method of the embodiment of the present invention uses the model to drive software development. On the basis of building a software requirement model, a design model and a test model are derived, and the established requirement, design and test models are exported as a standard model, which can be reused for embedded software development in the same field. In addition, the LUA language is used to create software templates, and each chapter is marked with functional requirements, pictures and tables. When customizing software requirement, design, system test case and unit test case templates, relevant templates are called as needed, and based on the various models that have been built, the function of generating software requirement, design, system test case and unit test case documents with one click is realized.

[0037] In a specific implementation method of an embodiment of the present invention, a requirement model of an embedded software system to be developed is established based on the requirement analysis of an embedded software system program, including: compiling a requirement data dictionary based on the key functional information of the requirements in the embedded software development project file, combining the system external interface relationship in the embedded software development task book and the requirement data dictionary to construct the corresponding requirement model.

[0038] During the specific implementation, the key functional information of the requirements in the project file is compiled into a requirements data dictionary; the corresponding requirements model is constructed by combining the system external interface relationship and the requirements data dictionary in the software development task book, and the data specifications of the processing and terminals in the requirements model, and the input and output data flow / control flow between each other are defined. The data specifications of the processing and terminals use a combination of data dictionary elements and regular expressions to specifically describe the input and output data items, and the consistency of the input and output data items is checked; the system modules are decomposed layer by layer until the smallest module is reached, and the requirements model is constructed.

[0039] In a specific implementation of the embodiment of the present invention, a system test case model is created based on the requirement model, including: setting the processed data specification and attribute strategy according to the requirement model and the requirement data dictionary, and creating the system test case model.

[0040] In a specific implementation of an embodiment of the present invention, a design model is derived according to the requirement model, including: configuring ports, data flows, and control flows between software modules and interface modules according to functional requirements, and using requirement data dictionary elements to describe the data item functions of soft components, data flows, and control flows; checking and decomposing each software module until the smallest soft unit, adding corresponding input and output variables and global variables to the soft unit, drawing software flow charts, and generating pseudocode; and using a semi-automatic method to generate design model software code by combining design model architecture code generation and manual addition of related code.

[0041] In a specific implementation of the embodiment of the present invention, according to the test standard, a unit test attribute is set for the minimum processing unit in the design model using a regular expression to generate a unit test case model.

[0042] In a specific implementation of the embodiment of the present invention, the software templates of the requirement model, the design model, the unit test case model and the system test case model of the embedded software system are customized respectively using LUA language.

[0043] During the specific implementation, the software templates of the requirement model, the design model, the unit test case model and the system test case model of the embedded software system are customized using the LUA language, the functional requirements of the constructed requirement model, design model, unit test case model and system test case model are obtained through the code, and non-functional requirements such as general quality characteristics are defined using natural language; finally, the software documents corresponding to each model are generated with one click.

[0044] In a specific implementation of an embodiment of the present invention, the software templates of the requirement model, the design model, the unit test case model and the system test case model of the embedded software system are customized respectively, including: analyzing the template structure of the document corresponding to each model software, constructing a template structure for each chapter in the document, configuring the template structure of each chapter with the corresponding data acquisition method or data information, and finally completing the composition and data input configuration of the software template framework and exporting it as the software template of each model.

[0045] In the specific implementation, the specific method of using LUA language to customize the software template of each model is as follows:

[0046] (1) Analyze the template structure of the software document, construct a template structure for each chapter, identify and classify the functional requirement texts, tables, and pictures that need to be dynamically updated in the document, and make templates corresponding to each part; use natural language to describe the functional performance, reliability and other indicators for the non-dynamically updated parts;

[0047] (2) Filter different functional requirement texts, tables, and picture mark configurations to associate corresponding data acquisition methods or data information, complete the software template framework composition and data input configuration, and export them as software templates;

[0048] Among them, the functional requirement text describes the specific functional requirements in chapters based on the constructed model hierarchy by binding the model hierarchy number and name. For example, the first-level system processing diagram in the requirement model corresponds to Chapter 1 Initializing the System; the second-level software processing diagram corresponds to Section 1.1 Initializing Peripherals.

[0049] Image tag configuration starts with {export template begin@} and ends with {@export template end}. After obtaining the model image in the tag content, set the image number, name, size, color and other information if the image is not empty. In addition, the number and name of the image need to be dynamically obtained and updated in the tag below the image.

[0050] Table tag configuration dynamically adjusts the number of table rows based on the number of data flows / control flows processed in the model, obtains relevant attribute information processed in the model as needed, fills the table in sequence, and sets text font, size and other formats.

[0051] Finally, based on the existing model, import the customized software template and generate the software documentation of the relevant model with one click.
