Trechoro is Sparx Systems’ dedicated SysML v2 modeling environment in Enterprise Architect. It implements SysML v2 and KerML natively with a modeling‑first approach, independent of UML. Trechoro supports graphical and textual authoring, scales to large repositories, and preserves traceability with existing assets via controlled referencing and performance for distributed teams.
Introduced at the Sparx Systems Global Summit 2025, Trechoro delivers a clean, high‑performance SysML v2 experience: native KerML alignment, UML‑free internals, and synchronized graphical + textual authoring. Rendering acceleration via Sparx Pro Cloud Server keeps large, distributed repositories responsive. Controlled referencing maintains links to existing UML/SysML 1.x assets, work items, and reviews.
SysML v2 is the OMG®’s modern language for systems engineering, created to make models more precise, expressive, and usable in day‑to‑day work. It evolves SysML 1.x with a leaner metamodel and a single, coherent graphical‑plus‑textual notation. With formally specified semantics and stronger MBSE constructs, teams can describe, analyze, and verify systems in one consistent model.
Designed for reuse, scale, and machine readability, SysML v2 fits today’s digital‑engineering pipelines from concept to verification. It strengthens end‑to‑end traceability, connects cleanly with broader toolchains, and enables executable models for simulation and analysis. Across aerospace, automotive, defense, and other complex product domains, it aligns intent, architecture, and analysis in a unified framework and is quickly becoming the standard for robust, model‑based development.
KerML (Kernel Modeling Language) is the OMG®-standard metamodel that underpins SysML v2. It supplies the language’s core semantics and structure—defining universal modeling primitives such as types, features, relationships, and behaviors. By providing a precise kernel, KerML ensures models are consistent, interpretable, and portable across tools and domains at enterprise scale.
Trechoro works directly on KerML, expressing elements in the same structures defined by the specification. This native alignment enables semantically rich, standards‑compliant models, clearer inheritance, and reliable automation. It also improves responsiveness on very large repositories and keeps traceability clean when linking to UML or SysML 1.x content.
In the initial release, Sparx Systems Enterprise Architect Trechoro aims to support:
