MATLAB/Simulink Testing with TPT - PikeTec

MATLAB/Simulink Testing with TPT
Model Based Testing MATLAB/Simulink Stateow TargetLink
TPT oers unique and all-encompassing support for testing
MATLAB/Simulink/Stateow- and TargetLink models. The strengths of both systems
can be used because of the perfectly tuned interface between TPT and
MATLAB/Simulink. Functional models are created normally in MATLAB/Simulink,
Stateow and TargetLink. Then the associated test models are created in TPT. The
integration feature of TPT with MATLAB/Simulink ensures an ecient execution and
an eective test process.

MATLAB/Simulink Testing MATLAB
with TPT
Model and interface analysis
In order to make the test models simple to
create and easy to reuse, TPT extracts the
interface information for the functional
models and inserts this into the test model.
TPT takes the subsystem model to be tested,
automatically handles the interfacing and
analysis of complex signals, the vectors,
busses, multiplexer. The TPT interfaces can
also be manually adapted or corrected if
necessary.
Test-frame generation
TPT requires a test-frame model for test
execution which contains a copy of the
complete sub system behaviour and a
special TPT execution engine. The creation
of the TPT test-frame model is completely
automatic, if desired.
Important features of the integration:
- Full support of MATLAB/Simulink 6.1 to 2007b
- Full support of TargetLink 1.3 to 2.2.1
- Automatic interface analysis
- Automatic generation of the test-frame models
- Comparison of test results through Back-to-Back-Analysis
- Flexible conguration options by way of M-script support
- Bi-directional exchange of parameters
- Reusability of tests between MiL, SiL, PiL and HiL
Test execution
All aspects of test execution management are
handled by TPT. This means that TPT starts
the appropriate version of MATLAB with
required system components and loads the
complete MATLAB models necessary for test
execution. Afterwards TPT exchanges model
parameter binding with MATLAB. In this way
all the parameters in the MATLAB model can
be accessed in the TPT test model and
modied for each and every test case.
Afterwards TPT selects and executes the
appropriate test cases and handles the
logging of all signals relevant to the test in
order to automatically evaluate the results
and include the data in the test report.
Test execution control for MATLAB tests is
managed by TPT and complex tests can be
executed unattended in batch mode.
