Simulink Performance Tools 1.2 Release Notes

New Features

Note    The Simulink Performance Tools 1.2 incorporates changes introduced in the Simulink Performance Tools 1.1.1, which was initially released in Web-downloadable form after Release 12.1 was released, but before Release 13. These Release Notes describe those changes, as well as changes introduced after Version 1.1.1.

If you are upgrading from a release earlier than Release 12.1, then you should also see New Features in the Simulink Performance Tools 1.1 Release Notes.

Graphical Merge Tool Enhancements

This release provides the following enhancements to the Graphical Merge tool:

• Performance enhancements

• The enhancements reduce the time required to compare models.

• Support for SimMechanics and SimPowerSystems models

• This release recognizes and compares instances of SimMechanics and SimPowerSystems blocks

• Heuristic comparisons

• The heuristic comparison enables the tool to recognize block naming differences (i.e., instances of the same block that occur in the same place in both of the models being compared but under a different name in each case).

Model Coverage Tool Enhancements

Simulink Performance Tools 1.2 includes several enhancements to the Model Coverage Tool.

Redesigned Coverage Settings Dialog Box

The redesign groups related settings into tabbed panes, thereby improving the readability of the settings.

Multirun Coverage Reports

To display results for a series of runs, select Cumulative runs on the on the Report pane of the Coverage Settings dialog box.

Coverage of Additional Objects

In addition to the blocks covered in previous releases, this release covers the following blocks:

• Discrete-Time Integrator

• Instrumented for decision coverage when saturation limits enabled.

• Fcn

• Instrumented for condition coverage when root operator is a logical operator (&&, ||, and !).

• Rate Limiter

• Instrumented for decision coverage with respect to slew rates specified.

This release also extends coverage to Stateflow event and state temporal decisions

Cyclomatic Complexity Coverage

The Model Coverage Tool now computes the cyclomatic complexity of covered objects and includes the result by default in the summary and detail sections of the coverage report. See Coverage Analysis in the online documentation for more information.
