Correcting Over- and Underspecified Truth Tables

An overspecified truth table contains a decision that will never be executed because it is already specified in a previous decision in the Condition Table. An underspecified truth table lacks one or more possible decisions that might require an action to avoid undefined behavior in the application. Stateflow helps you correct over- and underspecified truth tables with the special error messages described in the following topics:

• Defining an Overspecified Truth Table -- Gives you an example of an overspecified truth table and a truth table that is not overspecified.
• Defining an Underspecified Truth Table -- Gives you an example of an underspecified truth table and a truth table that is not underspecified.
