Shape requirements into a trusted baseline
Turn fragmented requirements, documents, and engineering data into a more structured, analyzable, and verifiable foundation.
Build executable system understanding
Use models and digital twins to make system behavior visible, testable, and reusable earlier in the lifecycle.
Derive and align implementation under control
Create or assess implementation artifacts with stronger alignment between engineering intent and delivered system behavior.
Verify critical properties with greater rigor
Use simulation, formal verification, and traceable analysis to reduce project risk earlier and strengthen confidence.
Maintain confidence through change
Handle upgrades, modifications, and recurring lifecycle change with more control, repeatability, and reuse of evidence.
A better way to engineer confidence

With Prover
Applied in depth in railway signaling
Prover’s approach is relevant across safety-critical industries, and it is already applied in depth in railway signaling. For railway infrastructure managers, this means:
Structuring signaling requirements before tender, upgrade, or modernization
Reducing risk before FAT, SAT, and site testing
Generating safety evidence for certification and assessors
Managing upgrades and changes without losing behavioral control
A specification-driven, model-based, and formally verified approach
Prover connects requirements, modeling, implementation, verification, and lifecycle change into one more controllable engineering logic.
01
Requirement engineering
Make requirements more precise, structured, and analyzable before ambiguity becomes downstream risk and rework.
02
System modeling and prototyping
Create executable system understanding through models and digital twins that make behavior visible earlier.
03
Implementation under control
Support controlled derivation, generation, or assessment of implementation artifacts with stronger alignment to intent.
04
Verification and validation
Verify critical properties with greater rigor through simulation, formal verification, traceability, and structured evidence.
05
Change and lifecycle management
Maintain confidence through upgrades, modifications, and recurring change without rebuilding assurance from scratch.
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.

Built for safety-critical systems
Prover is relevant in industries where safety depends on electrical, electronic, and programmable electronic systems, where functional safety must be engineered across the lifecycle, and where IEC 61508 or related standards drive high demands on requirements, verification, evidence, and controlled change.
Railway signaling
Make requirements more precise, structured, and analyzable before ambiguity becomes downstream risk and rework.
Process automation
Safety-related control functions in industrial plants where proof, traceability, and controlled change are critical.
Energy and power systems
Protection, control, and automation environments where high assurance and safe evolution over time are essential.
Nuclear instrumentation and control
High-assurance environments where modernization, verification rigor, and audit-ready evidence are central.
Machinery and industrial safety systems
Software- and control-driven systems where functional safety depends on disciplined engineering.

Prover’s innovative solution bring benefits to many types of rail control projects
The project formalized Trafikverket’s signaling regulations by translating them into machine readable requirements and building internal competence in formal methods, paving the way for safer, more efficient, and fully digitalized railway signaling.
In this project, Prover enabled a safe and stepwise migration from legacy relay systems to a modern, PLC-integrated Traffic Management System for the Stockholm Metro.
In signaling design automation projects, we start by developing a digital twin of your existing, future, and conceptual systems.

And 100% secure system.
