Version 2.2 (R2008b) SystemTest™ Software Release Notes

Version 2.2 (R2008b) SystemTest Software

This table summarizes what's new in Version 2.2 (R2008b):

New features and changes introduced in this version are:

• Signal Builder Block Test Vector

• Multiple Test Vector Groups

• New Plot Element

• Simulink Design Verifier Data File Test Vector

• Model Coverage Support for Reference Blocks

• Run Status Hyperlink Change

Signal Builder Block Test Vector

If you have created a Simulink model test harness using a Signal Builder block, you can automate the running of all your test cases by integrating them into a SystemTest™ test. This also offers the ability to collect cumulative model coverage metrics for all your Signal Builder test cases.

For more information on this feature, see Creating Signal Builder Block Test Vectors

Multiple Test Vector Groups

The ability to create multiple test vector groups has been added to the SystemTest software. A test vector group is a collection of test vectors of the same length whose values are indexed sequentially with the other vectors in the group. Groups are commonly used for Monte Carlo and Design of Experiments (DOE) based testing, or when multiple vectors have a relationship (e.g. the mass and damping values of different throttle body types). Until R2008b, you could only create one test vector group.

For example, you could have a model of an automobile motor with two blocks – one block for the fuel system and one for the oxygen flow. Each block has a number of inports that are mapped to SystemTest vectors. In previous release you could not create a test that checks how the model behaves when performing a Monte Carlo test on both the fuel system and oxygen flow at the same time. With multiple test vector group support, you can now perform a Monte Carlo style test on both blocks, saving time in the test run.

For more information on this feature, see Creating Grouped Test Vectors.

New Plot Element

The new General Plot element offers support of all MATLAB plot types. You can plot any type of data, using any MATLAB plot types, or Simulink data.

The General Plot element allows you to plot data produced from a Simulink model. The supported data types are such [time signal] array, a structure, a structure with time, or a time series. Note that the element creates a line for each signal in the Simulink data. If time is not present, the signals are plotted against their indices.

You can also plot Simulink data provided by test vectors, such as the Signal Builder Block test vector, the Simulink Design Verifier Data File test vector, or the Spreadsheet Data test vector.

For more information on this feature, see Working with the Basic Elements > Basic Elements > General Plot Element in the SystemTest help.

Simulink Design Verifier Data File Test Vector

The Simulink Design Verifier Data File test vector can read test cases created by the Simulink^® Design Verifier™ software. In order to use this test vector, you need a Simulink Design Verifier data file with test cases.

To use this feature, you first run Simulink Design Verifier with the appropriate configuration. Then you can do one of two things:

• Generate a SystemTest harness for the model from Simulink. When it completes, a new test opens automatically in SystemTest and a Simulink Design Verifier Data File test vector is automatically created. This workflow is described in Automatically Creating a SystemTest Test Harness from Simulink Design Verifier.

• If you already have a data file from Simulink Design Verifier, you can create a test vector in SystemTest that uses the data, and configure overrides in a Simulink element. This workflow is described in Creating a Simulink Design Verifier Data File Test Vector.

Model Coverage Support for Reference Blocks

The SystemTest software now supports Model Coverage for Reference blocks. The Simulink element will allow model coverage to be gathered for referenced models.

For more information on this feature, see Using Simulink Model Coverage.

Run Status Hyperlink Change

Prior to R2008b, after a test ran, the Run Status pane contained a link "Open Test Results in Viewer." This is no longer available. However, you can still open the results in the Test Results Viewer by selecting the Tools > Test Results Viewer menu or setting the automatic launch option on the General tab in the Test Properties pane.

The hyperlink in Run Status has been replaced by a link that opens the test results object in MATLAB.
