Exclude Blocks From Custom Checks

This example shows how to exclude blocks from custom checks. To save time

during model development and verification, you might decide to exclude individual

blocks from custom checks in a Model Advisor analysis. By modifying the

sl_customization.m file to include the ModelAdvisor.Check.supportExclusion

and Simulink.ModelAdvisor.filterResultWithExclusion functions, you can exclude

your custom checks from:

• Simulink blocks

• Stateflow charts

This example shows how to exclude blocks from a custom check.

At the command prompt, type slvnvdemo_mdladv.

In the model window, double-click View demo sl_customization.m.

To exclude the custom check Check Simulink block font from blocks during Model

Advisor analysis, make three modifications to the sl_customization.m file.

Enable the Check Simulink block font check to support check

exclusions by using the ModelAdvisor.Check.supportExclusion

property. You can now exclude the check from model blocks.

After rec.setInputParametersLayoutGrid([3 2]);, add

rec.supportExclusion = true;. The check 1 section of the function

defineModelAdvisorChecks now looks like:

% --- sample check 1

rec = ModelAdvisor.Check('com.mathworks.sample.Check1');

rec.Title = 'Check Simulink block font';

rec.TitleTips = 'Example style three callback';

rec.setCallbackFcn(@SampleStyleThreeCallback,'None','StyleThree');

rec.setInputParametersLayoutGrid([3 2]);

rec.supportExclusion = true;

Use the Simulink.ModelAdvisor.filterResultWithExclusion function

to filter model objects causing a check warning or failure with checks

that have exclusions enabled. To do this, there are two locations in the

sl_customization.m file to modify, both in the [ResultDescription,

ResultDetails] = SampleStyleThreeCallback(system) function:
