Challenges in Low-Level Integration Testing of T2080 in Integrated Modular Architecture

Abstract

The aircraft’s mission system is subject to continual revision by removal or obsolete upgrades. In addition to user and integration requirements, security considerations have become a major driving force in the design of today’s avionics systems. To achieve this, system design uses functional risk analysis and abstract system description to provide a coherent design that meets certification needs. The objective of the study was to spot evaluation criteria that may allow developers and certification bodies to gauge specific real-time security-critical software development tools from a system security perspective. The report clarifies the context of software development tools in relevancy current aeronautical systems certification guidelines. Research efforts continue in two directions: (1) collecting data on instrument quality assessment efforts to consider possible future revisions of existing guidelines, and (2) create a classification for evaluating software development tools by identifying tool categories, characteristics, concerns, factors, and evaluation methods. The topic report has four components: (1) industry perspective, (2) expertise, (3) quality assessment, and (4) instrumental assessment. Data collected from the industry influences the assessment process and recommendations for development tooling practices. Several methods of instrument evaluation are described. The report presents the different types of tools identified during the research. This classification is prohibited within the scope of studies directed by DO-178C DAL standard. Finally, the report defines the tool evaluation structure and organization.
