Mission- and safety-critical systems are increasingly reliant on software. However, their development and qualification has become increasingly challenging: increasing size and more coupling between software and hardware layers has driven development cost to unaffordable levels. Mismatched assumptions at the architecture level, impacting quality attributes such as performance, timing, safety, reliability, are the leading causes and are difficult to test for. To cope with these issues, architecture must be established to identify problems earlier in the development process. Architecture-centric modeling technology has led to a model-based virtual system integration approach that permits early discovery of problems (integration, performance, etc.). Despite advances in this area, such technologies have found limited use due to the perceived modeling and analysis cost with limited value.
