The error you are facing is that the Stateflow model is missing an enumeration for the state ‘SELFTEST STATE’. This typically happens when the state is not correctly represented by an enumeration literal in your custom ‘enum’ definition. You may can refer to the following steps to resolve it:
- Ensure that your custom enumeration includes a literal for ‘SELFTEST STATE’.
- Make sure that each state in your Stateflow chart is uniquely represented by an enumeration literal. No two states should share the same enumeration value.
- Ensure that the Stateflow chart is using the correct enumeration type. You can set the state to use the enumeration by specifying the ‘EnumType’ property in the Stateflow chart properties.
- After making the changes, rebuild your model to ensure that the changes take effect.
Here is an example of how to define and use the enumeration in Stateflow:
Defining the Enumeration:
Create a new MATLAB class file, ‘StateEnum.m’ as given below:
classdef StateEnum < uint32
enumeration
IDLE(0)
INIT(1)
SELFTEST_STATE(2)
RUN(3)
% Add other states as needed
end
end
Using the Enumeration is Stateflow:
- Open your Stateflow chart and go to the properties of the Stateflow chart (right-click on the chart and select Properties).
- Set the ‘EnumType’ to ‘StateEnum’.
- Ensure that each state in the chart is correctly assigned to an enumeration literal.
Example Stateflow chart:
In your Stateflow chart, you should see states like this:
- IDLE -> StateEnum.IDLE
- INIT -> StateEnum.INIT
- SELFTEST STATE -> StateEnum.SELFTEST_STATE
- RUN -> StateEnum.RUN
