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

Simulation-ready models

A single source of truth across hardware, software, and systems teams.

01

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.

02

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.

03

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.

04

Interface & Data Modeling

  • Interface control modeling (data flows, protocols)
  • Timing and bandwidth modeling
  • Data dictionary standardization
05

Behavior Modeling & Simulation

  • State machines, activity diagrams
  • End-to-end scenario simulation
  • Performance modeling (latency, throughput)
06

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.
