System Architecture Virtual Integration: A Case StudyP. Feiler1, L. Wrage1, J. Hansson1,21: Software Engineering Institute, Carnegie Mellon University, Pittsburgh, PA 15213, USA2: Chalmers University of Technology, SE-412 96 Gothenburg, SwedenAbstract:Aerospaceindustryisexperiencingexponential growth in the size and complexity ofonboard software. It is also seeing a significantincrease in errors and rework of that software. All ofthose factors contribute to greater cost; the currentdevelopment process is reaching the limit ofaffordability of building safe aircraft. An internationalconsortiumofaerospacecompanieswithgovernment participation has initiated the SystemArchitecture Virtual Integration (SAVI) program,whose goal is to achieve an affordable solutionthrough a paradigm shift ofintegrate then build. Akey concept of this paradigm shift is an architecture-centric approach to analysis of virtually integratedsystem models with respect to multiple operationalquality attributes such as performance, safety, andreliability. By doing so early and throughout the lifecycle at different levels of fidelity, system-level faultsare discovered earlier in the life cycle—reducing risk,cost, and development time. The first phase of thisprogram demonstrated the feasibility of this newdevelopment process through a proof of conceptdemonstration and a return on investment analysis,which are the topics of this paper.Keywords: virtual integration, embedded softwaresystem, safety-critical, validation & verification1. IntroductionAerospace industry is experiencing exponentialgrowth in size, complexity, errors, rework and cost oftheir onboard software. The current developmentprocess is reaching the limit of affordability ofbuilding safe aircraft. The size in terms of sourcelines of code (SLOC) has doubled every four years.The cost 27M SLOC of software is estimated toexceed $10B (see Figure 1).
