Author and Simulate Basic Colors Sequence Diagram with Enumerations

This example shows how to author and simulate a sequence diagram containing a variable of data type Simulink.IntEnumType.

Define BasicColors.m Enumeration

Create an enumeration class called BasicColors. Define Red(0), Yellow(1), and Blue(2) as the enumerated values.

classdef BasicColors < Simulink.IntEnumType
  enumeration
    Red(0)
    Yellow(1)
    Blue(2)
  end

Open Enumeration Example Model

Open the EnumExample.slx architecture model that contains a sequence diagram that implements the BasicColors enumeration.

model = systemcomposer.openModel("EnumExample");

To inspect the Stateflow® Chart (Stateflow) block, double-click the source component.

The output data port, data, is typed by the BasicColors enumeration in this state chart, where the color changes from Red to Yellow as the model simulates.

Open Enumeration Sequence Diagram

To open the Architecture Views Gallery and access the EnumSequenceDiagram sequence diagram, go to Modeling > Sequence Diagram. To simulate the sequence diagram, click Run.

As the inEnum destination port inherits a value of 1 from the BasicColors enumeration, indicating a change from Red (0) to Yellow (1), the sequence diagram executes successfully.
