Data Dictionaries

A data dictionary is a file containing details about the variables defined in your design model. These variables can be inspected on the physical system using a calibration tool.

Selecting A Data Dictionary Format

OpenECU supports two types of data dictionaries:

  1. Tab-delimited text, as defined by OpenECU.

  2. Simulink data dictionary (.sldd), as defined by MATLAB and available from R2015a onwards.

Text-based data dictionaries can be divided into multiple files corresponding to your model’s architecture. These files are editable with any text editor or Microsoft Excel, and changes can be compared using any diff tool.

Simulink data dictionaries are proprietary and must be managed within Simulink or MATLAB. Simulink provides a Comparison Tool for comparing and merging dictionary changes.
