Our PRODUcts

Resulting from decades of experience with Enterprise Architect, LemonTree and Embedded Engineer are two plug-and-play products that will make your job much easier, faster, and more streamlined.


Managing different versions of the same model. LemonTree is the Plug & Play model versioning tool (Diff & Merge) that revolutionizes the work of a distributed modeling team and supports compliance with required standards such as ISO 26262. In this way, models get the same lifecycle as other artifacts (such as software). LemonTree provides a meaningful review of changes between individual model versions.

Embedded Engineer

Embedded Engineer combines automated source code generation with model-level debugging. This Plug & Play product offers optimized code generation of ANSI-C code from UML structures, state machines and activity models, as well as the generation of C++ source code. Embedded Engineer also guarantees the traceability of requirements to the code and back again.
