Runtime Monitor Using Temporal Logic for Requirement Validation

The patent implements a universal runtime monitor that can validate requirements across multiple different systems using the same infrastructure. The monitor translates requirements into temporal logic formulas and uses a single monitoring setup to validate various systems, eliminating the need for separate simulation or lab measurement setups for each system. This universal approach maintains validation accuracy while reducing resource consumption and increasing reusability.

The patent replaces traditional simulation-based or lab measurement-based monitoring methods with a formal methods approach using temporal logic. Requirements are translated into temporal logic formulas that can be automatically evaluated against system traces. This substitution enables precise violation detection through formal verification techniques while consuming fewer computational resources compared to running separate simulation or measurement setups.

The runtime monitor provides system-specific validation accuracy by translating each system's requirements into appropriate temporal logic formulas while maintaining a universal monitoring infrastructure. The same monitor can validate different systems by loading their specific requirements, eliminating the need to create separate simulation setups for each system. This approach maintains validation precision while significantly improving productivity through reusability.

The patent performs preliminary translation of requirements into temporal logic formulas before runtime monitoring. The requirement translation and formula generation are done in advance, allowing the runtime monitor to focus on evaluating traces against pre-compiled temporal logic specifications. This preliminary action reduces the complexity of the runtime monitor implementation while maintaining high validation accuracy through formal methods.
