eTrice Models and Their Relations

eTrice comprises several models:

• the ROOM model (*.room) – defines model classes and the logical structure of the model
• Config model (*.config) – defines configuration values for attributes
• Physical model (*.etphys) – defines the structure and properties of the physical system
• Mapping model (*.etmap) – defines a mapping from logical elements to physical elements

In the following diagram the models and their relations are depicted. The meaning of the arrows is: uses/references.

In the following sections we will describe those models with emphasis of their cross relations.
