Cathedral Blueprint - MBSE
Cathedral Blueprint helps systems engineering programs deliver complex, safety-critical systems faster and with less risk by replacing fragmented, document-based engineering with a model-based architecture and safety framework that improves predictability, reduces rework, and accelerates certification
A single source of truth across hardware, software, and systems teams.
System Architecture Modeling
SysML v1/v2 structural and behavioral models — block definitions, internal block diagrams, state machines — built in tools such as Cameo Systems Modeler or Capella.
Requirements Traceability
Requirements management setup that links every stakeholder need to design elements and test cases, so impact analysis is a query, not a re-read of every document.
Digital Twin & Simulation Support
Executable models and simulation harnesses that let you validate system behavior before hardware exists, catching architectural issues while they're still cheap to fix.
Interface & Data Modeling
- Interface control modeling (data flows, protocols)
- Timing and bandwidth modeling
- Data dictionary standardization
Behavior Modeling & Simulation
- State machines, activity diagrams
- End-to-end scenario simulation
- Performance modeling (latency, throughput)
Verification & Validation
- Model-based test case generation
- Requirement-to-test traceability
- Digital validation environments
What We Do.
We're brought in at program kickoff to establish the systems model that everything downstream references, or mid-program to retrofit traceability onto a system that's grown past what documents alone can track. In both cases, the model becomes the shared reference between systems, software, hardware, and V&V teams — the thing every discipline points back to.
