New Features

This section introduces the new features and enhancements added in Simulink

Performance Tools 1.1 since Simulink Performance Tools 1.0 (Release 12.0).

The following tools were enhanced:

• “Model Coverage Tool” on page 29-2

• “Graphical Merge Tool” on page 29-4

For an introduction to the Simulink Performance Tools, see the Release Notes

for Release 12.

Model Coverage Tool

This section describes features and enhancements added to the Model

Coverage Tool .

Additional Coverage Types

This version adds the following types of coverage analysis:

• Condition coverage

Examines blocks that output the logical combination of their inputs, e.g., the

Logic block, and Stateflow transitions. A test case achieves full coverage if it causes each input to each instance of a logic block in the model and each condition on a transition to be true at least once during the simulation and false at least once during the simulation.

• Modified condition/decision coverage (MC/DC)

Examines blocks that output the logical combination of their inputs, e.g., the

Logic block, and Stateflow transitions to determine the extent to which the test case tests the independence of logical inputs and transition conditions.

• Look-up table (LUT) coverage

Examines blocks, such as the Look-Up Table block, that output the result of looking up one or more inputs in a table of inputs and outputs, interpolating between or extrapolating from table entries as necessary. Lookup table coverage records the frequency that table lookups use at each interpolation interval.

See “Coverage Analysis” in the “Model Coverage Tool” section of Using

Simulink for more information.

New Features

See “Covered Blocks” in the “Model Coverage Tool” section of Using Simulink for more information.

Additional Coverage Reporting Options

This version provides the following additional coverage reporting options:

• Include each test in the model summary

• Produce bar graphs in the model summary

• Use two color bar graphs

• Display hit/count ratio in the model summary

• Don't report fully covered model objects

See “HTML Settings” in the “Model Coverage Tool” section Using Simulink for more information.

Hyperlink Enhancements

When you click a hyperlink to the model in a coverage report, the tool now opens the model, if it is not already open. Hyperlinks to the model in the coverage report now persist across Simulink sessions. This means that you no longer have to regenerate a report in order to use its hyperlinks.
