However, this increased reliance on software to enhance avionic system functionality raises crucial safety questions, emphasizing the need for compliance with standards like DO-178C/DO-331. To facilitate development, a process-oriented build tool was created in MATLAB/Simulink. This tool enhances development efficiency and ensures adherence to established processes, offering benefits like modular software management, systematic artifact handling with traceability, seamless integration with various verification tools, automated model and code verification, and a well-defined design environment. Recently, two new advancements have been made to the tool, integration of System Composer for developing software architecture and automated processor-in-the-loop (PIL) verification using Trace32. This paper presents these new developments along with examples.enDO-178CDO-331model-based softwareprocess-orientedsoftware architectureverificationText/Conference Paper10.18420/sw2024-ws_05
