The most important quality assurance activity in flight software development is techniques used for software verification and validation. When compared with conventional software, testing of real-time systems presents unique and challenging problems since various real-time constraints of the software also need to be verified. The real-time executive software component (REX) of onboard flight software should be tested for the real-time aspects to accurately evaluate the system performance in different implementation scenarios. This paper summarizes the Independent Verification and Validation strategy followed for REX Software.
