Novel methodology for requirements to design traceability of onboard software

This paper focuses on requirements to design traceability. There have been many advances in requirements traceability and various tools are available to perform requirements traceability. Software Requirements to Design Traceability Technique named SoRDeTT, is the methodology proposed, which is based on templates. Software Requirements Specification (SRS) and Software Design Document (SDD) form inputs to this methodology. SoRDeTT has defined a common template (for requirement and design) to capture data and information from these documents. The template with data populated from SRS is called SRS Trace Item (SRSTI), and the one filled with data from SDD is called SDD Trace Item (SDDTI). The template defined needs to be filled for every software requirement. Initialization, input, output, data type, range, resolution of data etc. are the fields which are part of the template. The filled templates namely SRSTI and SDDTI corresponding to all software requirements are used to carry out traceability analysis. Since the template is same for requirements and design data, hence it is easy to compare and raise alerts for appropriate action to be taken.
