LCF is a domain specific language tailored for signaling engineering. It gives you a universal way of expressing signaling domain configuration data in a compact and review-friendly format.
LCF enables you to specify and express signaling configuration data in a uniform way, adaptable to any set of signaling principles and any choice of interlocking platforms using a powerful generic application configuration methodology. The methodology is object-model based and consists of (predefined and user-defined) generic components that are instantiated, interconnected and configured.
The LCF format, together with Provers associated tool suite, offers an extensive machinery for checking correctness and consistency, and for computing derived data for use in design, testing, or formal verification of interlocking software. The configuration of this machinery is highly flexible and the resulting process is CENELEC SIL-4 compliant.
