Table 3 Techniques selected for design specification [13]. The three columns report respectively the technique name, a brief description of the technique, and its implementation
From: Development and validation of a safe communication protocol compliant to railway standards
Technique | Description | Implementation |
|---|---|---|
Modular approach | Decomposition of a software into small comprehensible parts in order to limit the complexity of the software | Definition of different SW modules depending on functionalities needed. |
Components | Well-defined interfaces and behaviour with respect to the software architecture and design | Fully defined interface, parameter number limit |
Modelling | Use of precise and field-specific graphical formalisms to provide a complete description of the system and its parts. | Control flow, state-transition and structure diagrams |
Design and coding standard | To ensure a uniform layout of the design documents and the produced code, enforce consistent programming and to enforce a standard design method which avoids errors. | MISRA C 2012 coding standard [25], adequate coding styles |
Strongly typed programming language | Reduce the probability of faults by using a language which permits a high level of checking by the compiler | Subset of the standard C99: MISRA C 2012 coding standard [25] |
