C CLOE
Requirements · MBSE · IVV · Traceability

All your system engineering.
One platform.

CLOE unifies requirements management, MBSE models, verification campaigns and end-to-end traceability — so your team stops juggling DOORS exports, Capella files and spreadsheets.

Features

Everything a system team needs, connected

Each artifact lives in the same workspace and can be linked to any other — requirements, models, tests — feeding live indicators.

Requirements as documents

Structured requirement documents with rich text, auto-numbered REQ IDs, MoSCoW priorities, verification methods and statuses — like DOORS, without the pain.

MBSE diagrams

Operational, functional, logical and physical architecture diagrams in a modern editor. Model your system from need to implementation.

IVV campaigns

Plan integration, verification and validation tests, record expected results and pass/fail status — dashboards update in real time.

End-to-end traceability

Typed links between any artifacts: JUSTIFIES, IS TESTED BY, DEPENDS ON… Navigate from a requirement to its tests in one click.

Live traceability matrix

Instant coverage analysis: which requirements are covered, verified, or failing — with orphan test detection and smart filters.

Open data, no lock-in

One-click JSON export of a full project, CSV exports for every module, and JSON re-import to duplicate or restore. Your data stays yours.

How it works

From need to verified system in three steps

CLOE follows the V-cycle your team already knows — it just removes the friction between its branches.

Capture & model

Write requirement documents and build MBSE diagrams for each engineering layer — operational, functional, logical, physical.

Link everything

Connect requirements to functions and tests with typed traceability links. CLOE keeps the graph consistent as things evolve.

Verify & prove

Run IVV campaigns, watch coverage climb on the live matrix, and export audit-ready evidence for your client or certification body.
