Component Verification Approaches
Component verification allows you to test a design component in your model using one of
two approaches:
• Within the context of the model that contains the component — Using systematic
simulation of closed-loop controllers requires that you verify components within a
control system model. Doing so allows you to test the control algorithms with your
model. This approach is called system analysis.
• As standalone components — For a high level of confidence in the component
algorithm, verify the component in isolation from the rest of the system. This
approach is called component analysis.
Verifying standalone components provides several advantages:
• You can use the analysis to focus on portions of the design that you cannot test
because of the physical limitations of the system being controlled.
• You can use this approach for open-loop simulations to test the plant model
without feedback control.
• You can use this approach when the model is not yet available or when you need to
simulate a control system model in accelerated mode for performance reasons.
Simulink Verification and Validation Tools for Component Verification
By isolating the component to verify and using tools that the Simulink Verification and
Validation software provides, you create test cases that allow you to expand the scope of
the testing for large models. This expanded testing helps you accomplish the following:
• Achieve 100% model coverage — If certain model components do not record 100%
coverage, the top-level model cannot achieve 100% coverage. By verifying these
