Comparison Tool

View differences between two architecture models

Description

The Comparison Tool in System Composer™ shows differences between two architecture models.

The tool shows differences for these types of architectural data:

  • Model structural differences (components, ports, and connectors)

  • Different types of supported components and ports

  • Interfaces on model data dictionaries

  • Owned port interfaces

  • Applied stereotypes and property value changes on model elements

  • Architecture views

  • Parameters

  • Simulink® properties

Rows in the comparison report are highlighted according to the type of difference:

  • Insertion teal highlight — Added elements to the right side that did not exist on the left side

  • Deletion gold highlight — Removed elements that did exist on the left side but not on the right side

  • Modification purple highlight — Changes to existing elements that exist on both the left and right sides

Comparison Tool

Open the Comparison Tool

  • Open the Comparison Tool from the System Composer toolstrip.

    1. Navigate to Modeling > Compare.

    2. In the Select Files or Folders for Comparison dialog box, select the second file against which to compare.

    3. Set the comparison type as System Composer Model Comparison.

    4. Click Compare.

    Select files or folders for comparison.

  • Open the Comparison Tool from the MATLAB® file manager by selecting one architecture model.

    1. In the MATLAB® file manager, right-click an architecture model.

    2. Select Compare Against and then Choose.

    3. In the Select Files or Folders for Comparison dialog box, select the second file against which to compare.

    4. Set the comparison type as System Composer Model Comparison.

    5. Click Compare.

  • Open the Comparison Tool from the MATLAB® file manager by selecting two architecture models.

    1. In the MATLAB® file manager, select two architecture models.

    2. Right-click and select Compare Selected Files/Folders.

Parameters

Swap sides of the two models being compared on the comparison report.

When the architecture models are out of sync, pull in the changes to the comparison report. You must save both architecture models first before clicking Refresh.

When Always Highlight is turned off, you can click Highlight Now to highlight the currently selected comparison report node in the architecture models.

By default, the two models being compared display to the right of the comparison report, with the model corresponding to the left side of the report on top and the model corresponding to the right side appearing below. Turn Always Highlight off to use the Highlight Now button and control highlighting in the models.

Access this check box from the Filter menu. When selected, graphical changes such as component positioning and resizing are ignored from the comparison report.
