Find the right way to improve your signaling lifecycle
Railway Signaling Automation with formal methods and digital twin
Explore common use cases for stronger requirements, earlier verification, safer change, better safety evidence, and more predictable modernization.
We digitalize the railway by implementing Signaling Design Automation, leveraging our expertise in formal methods and digital twins.
Where do you need to improve?
Choose the challenge you want to solve, then go deeper into the use case, the typical outcome, and the best way to start.
01
Improve requirements and specifications
Reduce ambiguity, improve quality earlier, and create a stronger foundation for downstream engineering and verification.
02
Fix data quality and inputs
Turn incomplete, inconsistent, or unreliable signaling data into a trusted baseline for engineering, simulation, and V&V.
03
Reduce acceptance and testing risk
Find issues earlier, improve coverage, and reduce surprises before FAT, SAT, and site testing.
04
Automate design and engineering
Move from manual and error-prone processes to more scalable, repeatable signaling design automation.
05
Generate safety evidence for certification
Create more consistent, traceable, and assessor-ready evidence for sign-off and acceptance.
06
Manage system changes safely
Maintain control across modifications, upgrades, and recurring change with stronger confidence in impact and reuse.
07
Modernize legacy signaling systems
Support safer migration from legacy environments to more open, maintainable, and future-ready signaling architectures.
— How Prover works
One structured approach across the railway signaling lifecycle
From baseline definition to project verification to lifecycle change, Prover helps create a more controllable and scalable signaling lifecycle.
Trusted baseline
Structure requirements, data, and signaling logic into a trusted baseline before risk moves downstream.
Project confidence
Model, simulate, and verify system behavior to reduce acceptance risk and improve project confidence.
Begin with a focused engagement
Most customers start with a bounded engagement that proves value quickly and creates a practical path toward broader adoption – especially in railway signaling.
Starter
Specification Intelligence Starter
Build a stronger understanding of existing railway systems and requirements before change, tendering, or modernization.

Prover SDA Software Suite – Verify safety in every step of your project.
Prover SDA Software Suite is a complete process and tool suite that reduces engineering efforts and life cycle costs, provide prompt time-to-market, and ensures certification to the highest available safety standards.
Our software suite contains the following three solutions: Prover Studio, Prover iLock, and Prover Certifier.
The desktop tool for producing fully documented, tested and verified application software for railway signaling systems.
The only sign-off verification tool on the market that allows you to automatically produce complete safety evidence using formal verification.
The software tool for automated processing, checking and generation of Relay-Based Interlocking (RBI) system schematics.
Prover PSL is a model checker capable of formally verifying big industrial systems. It supports HLL and sHLL.
Your way to ensure that no one makes unnoted changes to approved documents, drawings or programs.
