— Why Prover

Because safety-critical engineering needs confidence you can prove

Railway Signaling Automation with formal methods and digital twin

Safety-critical systems are becoming more software-driven, data-dependent, modular, and continuously evolving. At the same time, engineering teams are under pressure to move faster, manage more complexity, produce stronger evidence, and maintain confidence through every change.

Prover helps organizations turn requirements, verification, evidence, and lifecycle change into a more structured, repeatable, and formally supported engineering process.

We digitalize the railway by implementing Signaling Design Automation, leveraging our expertise in formal methods and digital twins.

— The challenge

Functional safety is becoming harder to prove and maintain

In safety-critical engineering, the challenge is no longer only to design safe systems. The challenge is to prove, document, and maintain safety in a controlled way over time.

Fragmented inputs

Requirements often live across documents, spreadsheets, legacy systems, standards, supplier deliverables, and expert knowledge.

Late verification

Verification may happen late, when changes are already expensive and uncertainty has already moved downstream.

Manual evidence

Evidence is often assembled manually before audits, acceptance, or certification.

Change uncertainty

Every modification can trigger new uncertainty about what has changed, what must be rechecked, and what can still be trusted.

Growing complexity

As systems become more software-driven and connected, engineering teams need a better way to reduce ambiguity and verify behavior with greater rigor.

The reason Prover exists

Engineering teams need to generate stronger evidence and maintain confidence through upgrades, releases, migrations, and changes.

— What makes Prover different?

A specification-driven,
model-based, and formally verified approach

Prover brings together software, formal methods, domain expertise, and engineering services in one coherent methodology.

Shape requirements into a trusted baseline

Prover helps transform natural-language requirements, documents, rules, and engineering data into structured, analyzable, and verifiable specifications.

Build executable system understanding

Prover helps create executable models and digital twins that make system behavior visible, testable, and reusable earlier in the lifecycle.

Keep implementation under control

Prover supports controlled derivation, generation, or assessment of implementation artifacts so that delivered behavior remains aligned with engineering intent.

Verify critical properties with greater rigor

Prover uses simulation, formal verification, traceability, and structured analysis to help prove that critical properties hold under defined assumptions and modeled conditions.

Maintain confidence through change

Prover helps teams manage upgrades, modifications, migrations, and recurring releases with stronger control.

— Lifecycle value

From a trusted foundation to
controlled lifecycle change

Prover creates value across three connected stages of the safety-critical engineering lifecycle.

Level 0 — Create the truth

Trusted foundation

Before teams can automate, verify, certify, or modernize with confidence, they need trusted inputs. Prover helps turn fragmented requirements, documents, data, assumptions,
interfaces, and system knowledge into a structured baseline that can be analyzed, reused, and verified.

Level 1 — Build and prove

Project execution

Once the foundation is trusted, teams need to execute with greater confidence. Prover helps engineering teams use executable models, simulation, formal verification, conformance checking, and evidence generation to reduce project risk earlier.

Level 2 — Evolve safely

Lifecycle and change

Safety-critical systems do not stand still. Prover helps teams preserve confidence through change by supporting impact analysis, reusable baselines, incremental re-verification, and updated evidence.

— Why Prover in the AI era?

AI increases speed.
Prover helps ensure trust.

AI is increasingly supporting requirements analysis, specification review, model generation, code and configuration assistance, test generation, documentation, evidence drafting, and change
analysis.

Faster output only creates value if the output can be trusted. AI-generated or AI-assisted artifacts can look structured and convincing while still being incomplete, inconsistent, or wrong.

In safety-critical systems, a subtle error in a requirement, model, interface assumption, configuration file, or generated artifact can create a risk that may not appear in ordinary testing.

Prover provides a practical trust layer for AI-assisted engineering. With structured requirements, executable models, conformance checking, formal verification, traceable evidence, and controlled lifecycle change, Prover helps teams use AI-enabled speed without losing engineering control.

AI can help generate. Prover helps verify, validate, and build trust.

— Proven in railway signaling

Applied in one of the world’s most demanding safety-critical domains

Prover’s approach is relevant wherever functional safety depends on requirements, verification, evidence, and controlled change. It is already applied in depth in railway signaling.

Railway signaling is one of the most demanding safety-critical engineering environments. Systems must operate safely over long lifecycles, integrate with legacy infrastructure, support complex operational rules, and meet strict assurance
requirements.

Prover works with railway infrastructure managers, signaling suppliers, system integrators, and engineering partners to improve how signaling systems are specified, modeled, verified, automated, accepted, maintained, and modernized.
