railway-simulation

This project is a railway network simulation that models trains, switches, and signaling systems. Its core innovation is the use of the SPARK language (a subset of Ada) to formally prove the correctness of the signaling logic, ensuring that trains cannot collide under any scenario.

Key Features

• Formally Verified Signaling — The signaling system is mathematically proven using SPARK to prevent train collisions.
• Railway Network Simulation — Simulates trains, switches, and track layouts in a controlled environment.
• Hardware Deployment — Can be flashed and run on an STM32F429 Discovery board for real-world demonstration.

Philosophy

The project emphasizes safety-critical software engineering through formal verification, demonstrating how SPARK can be used to build high-assurance systems where failure is not an option.
