DO-178B standard document generator

Abstract

The invention discloses a DO-178B document generator, belonging to the field of software engineering automation. The DO-178B document generator is characterized by decomposing and organizing data items of a plurality of documents, compiling, modifying and querying the documents in the mode of a WEB page, and automatically querying the content of the data items from a database, taking out document formats from a template base and generating various documents. The invention can radically overcome multiple difficulties in the traditional document compilation, realize immediate update of document content, guarantee the content consistency of different documents, ensure the completeness of each document, realize concurrent work of document compilation of a large-scale team, avoid document conflict, meet the requirements of the military on different formats, reduce the workload on compilation, improve the efficiency on document compilation and save the time on document compilation.

Description

technical field [0001] The invention can automatically generate multiple types of documents that need to be written in the development process of aviation airborne software meeting the DO-178B standard, and belongs to the field of software engineering automation tools. Background technique [0002] DO-178B is an international civil aviation airborne software development and review standard formulated and promulgated by RTCA and EUROCAE. The development of all civil aviation airborne software in the world needs to meet the DO-178B standard. At the same time, many military aviation airborne software in the world are also developed and reviewed according to the DO-178B standard, such as A400M, EC 225 in Europe, C-130J, C-17 in the United States, and the XXX project in my country (involving password, do not provide a name) and so on. [0003] According to the DO-178B standard, a large number of documents need to be written during the software development process, and a large am...

AI Technical Summary

Problems solved by technology

These same contents appear in many different documents, but these contents are changed every day during the document compilation process, and it is difficult to maintain the consistency of these contents in each document

[0005] Question 2. In addition to the above-mentioned repeated content, many contents between different files are closely related

[0006] Question 3. Due to the above two reasons, software developers, software verification personnel, software configuration management personnel, and software quality assurance personnel who write various documents need a lot of coordination and information update activities

Although information updates to a certain extent can be achieved through version management tools, such information updates are not instant, resulting in difficulties in coordination

[0007] Question 4. In the traditional document writing process, there is another serious problem that multiple people need to modify the same file at the same time, which leads to the contradiction between parallel document writing and file conflict merging

Common version management tools can only solve one of the problems, either achieve a certain degree of parallel writing of documents, but this will lead to a large number of document conflicts; or use a mutual exclusion mechanism to prevent document conflicts, but this cannot achieve multiple personnel Write documents in parallel, reducing efficiency

[0008] Question 5. The DO-178B standard puts forward strict requirements on the content of these documents. In the process of compiling this series of documents, the software development unit often has the phenomenon of taking care of one thing and neglecting the other, missing some content and failing to meet the requirements of DO-178B

This requires a lot of maintenance work and the data needs to be rechecked and maintained whenever the baseline changes (e.g. due to reviews, audits, etc.)
