Designing Future Aerospace Systems: Integrating BIP Formal Verification Into F Prime Framework

Traditional component-based frameworks (CBFs), such as NASA’s F Prime, promote modularity and reuse but lack native support for formal verification, limiting their applicability in safety-critical and real-time domains. Ensuring deterministic behavior and correct synchronization remains a major challenge, especially on multicore embedded platforms. To address this gap, we propose a novel integration of the Behavior-Interaction-Priority (BIP) framework with F Prime, enabling correctness-by-construction through formal modeling and verification. Our methodology translates F Prime components into BIP models, allowing the use of priority rules and interaction semantics to detect race conditions and enforce synchronization determinism. We evaluate this hybrid framework on a Raspberry Pi 3 Model B platform, under both default Linux and PREEMPT_RT kernels, comparing two execution configurations: SYNC (synchronized mode updates via priority messages) and UNSYNC (sequential thread-level updates). Experimental results reveal that SYNC mode, when coupled with real-time kernel support, significantly reduces execution time variability and latency spikes, demonstrating improved synchronization and predictability. This integration enhances the reliability of modular embedded software while offering a practical pathway to adopt formal methods in industry-grade systems.
