What It Is

SafetyML (Safety Modeling Language) is a safety modeling language from PivotPoint Technology Corporation. It is positioned not as a traditional code development framework, but as a UML/SysML Profile and model library for safety-critical systems. It is used to describe system architecture, design, and safety analysis models, covering scenarios that require functional safety methods, such as automotive, aerospace, medical devices, and rail.

Core Capabilities

Functionally, SafetyML provides safety-related constructs such as SIL, hazard, risk, reliability, availability, fault, error, failure, failure mode, failure cause, and harmful effect. Through recursive analysis, design, and architecture patterns, it spans the SDLC and the System V-Model. It emphasizes traceability support on the left side and Verification & Validation support on the right side. It can extend SysML requirements, activity, block definition, internal block, parametric, sequence, and state machine diagrams, and can also extend UML 2 requirements, activity, class, composite structure, sequence, and state machine diagrams.

Ecosystem, Pricing, and Documentation

SafetyML’s main advantage is compatibility with UML 2 and OMG SysML, so in theory it can be implemented in visual modeling tools that conform to these standards. If supported by the tool, behavioral diagram simulation, parametric simulation, and round-trip engineering may also be possible. The official website does not disclose whether it is open source or closed source, its license, download method, API/SDK, self-hosting options, or specific pricing. It only mentions that SafetyML is being used in PivotPoint’s Model-Based Functional Safety + SafetyML hands-on training. The current documentation reads more like an FAQ and conceptual introduction, and lacks practical reference manuals and example models.

Pros, Cons, and Who It’s For

Its strengths are its focused domain scope, concise concepts, and attempt to reduce the complexity of full BUFD modeling languages through an Agile/Lean UML/SysML subset. For teams already familiar with UML/SysML, the official site says it can be learned through a 2–3 day hands-on workshop. The limitations are insufficient information transparency, difficulty for ordinary developers to try it directly, and value that depends heavily on the modeling tools used and the maturity of the organization’s safety engineering processes.

Access from China

The collected text does not provide information about network access, payments, or local support in China, so its access status can only be marked as unknown. Domestic teams evaluating it may also want to compare general-purpose UML/SysML toolchains, standard SysML modeling methods, and existing functional safety process tools.
