Railway Functional Safety Automation
Next-Gen Signaling. Zero-Compromise Safety.
Automate EN 50128 SIL 4 Compliance for ETCS and CBTC Systems.
Tymaton is the world’s first Autonomous Functional Safety Engineer for the railway industry. We bridge the gap between legacy signaling infrastructure and modern digital control, automating the rigorous verification required for CENELEC EN 50128 SIL 4 certification. Deliver safer trains faster, with mathematically proven reliability.
The "Long-Lifecycle" Trap in Railway Engineering
The railway industry faces a unique contradiction: it must maintain safety-critical systems for 30+ years while integrating modern digital standards (ERTMS/ETCS).
The SIL 4 Barrier
Achieving Safety Integrity Level (SIL) 4 requires the highest level of rigor, where the probability of failure on demand (PFD) must be less than 10 −8 . Manual verification of this magnitude is slow and prohibitively expensive
Legacy "Spaghetti Code"
Decades of patches and updates create architectural erosion in signaling software. Validating changes in these fragile environments often requires full regression testing, which is time-consuming and error-prone
The Documentation Mountain
CENELEC standards (EN 50126/50128/50129) require massive documentation for the Safety Case. Manually synchronizing requirements, code, and test results for every software update is a primary cause of project delays
Deterministic Automation for High-Speed Rail
Tymaton applies advanced "Hybrid AI" and architectural discipline to solve the headaches of railway software validation, ensuring compliance from the interlocking logic to the onboard computer

100% MC/DC for SIL 4 (Hybrid AI)
Ensure no requirement is left untested. Tymaton integrates seamlessly with Jama and CodeBeamer to link requirements, code, and test results automatically
Hybrid Solver
We combine Z3 SMT Solvers (formal methods) with Large Language Models (LLMs) to generate test vectors that achieve 100% Modified Condition/Decision Coverage (MC/DC). This guarantees that every logic gate in your interlocking or braking system is tested and verified
Unreachable Code Detection
Tymaton identifies "dead code" (unreachable instructions) using Control Flow Analysis (CFA), ensuring that your deployed software contains only verified, executable logic as required by EN 50128

Mastering Legacy Code with DSM
Railway projects rarely start from scratch. TimeZero helps you manage the evolution of long-lifecycle assets.
Architectural Visualization
Using Dependency Structure Matrix (DSM) technology, TimeZero creates a visual heatmap of your software architecture. It highlights "bad dependencies" (e.g., UI layers calling Safety Kernels directly) that violate modularity and safety concepts
Safe Refactoring
The platform acts as a guardrail, allowing engineers to refactor legacy C/C++ code for modernization (e.g., moving to LTE/5G signaling) without introducing regression faults

​Automated Safety Case Generation
Turn the bureaucratic burden into an automated process.
Traceability Matrices
Tymaton automatically links Requirements → Architecture → Code → Test Results.

Evidence Packs
Generate the specific artifacts required by Independent Safety Assessors (ISAs), including Software Requirement Specs (SRS), Software Design Specs (SDS), and Verification Reports, drastically reducing the time required for final safety audits
Real-Time MISRA & CENELEC Compliance
Ensure code quality from the first keystroke.
Static Analysis
TimeZero enforces MISRA C/C++ rules in real-time within VS Code. This prevents common coding errors (buffer overflows, uninitialized variables) that could lead to dangerous failures in Train Control Management Systems (TCMS)
