I wonder if you have seen our preemptive version ？

· Model dynamic testing tool TPT 18 The new version goes online , Help test efficiency one step faster
· Model dynamic testing tool TPT 18 More new features ——HiL test 、 demand management
·TPT 18 Function expansion and update ：IBM ALM, Equivalence class ,ADAS test , Code debugging

Now we will introduce it in detail ：

One 、 Formal needs assessment

Do you want to edit requirements without writing assessments ？ Now? TPT18 Formal needs assessment can meet this requirement .

Formal requirements are concise 、 Clear and evaluable characteristics . stay TPT18 in , You can import Excel Requirements are translated into formal requirements assessment . Formal requirements are not just requirements covered by link relationships , It's a more direct assessment of needs .

such as , Lamp control model requirements SPEC-17, It can be translated into the following formal requirements assessment .

chart 1 Formal needs assessment

The test results are as follows .

chart 2 test result

Two 、 More flexible requirements management

TPT18 front , Functional requirements can only be imported from outside , Can't be in TPT Change in . Although this can ensure the unity of requirements , But it also brings inconvenience to the change of functional requirements . stay TPT18 in , But directly in Requirements Change in / Create a new functional requirement / Sub functional requirements , And the requirements will not change with the introduction of functional requirements .

3、 ... and 、 TASMO Support MC/DC Automatically generate test cases

What if the test coverage fails to meet the requirements ？ Consider using TASMO.TASMO According to the model / Code structure generates test cases , Improve test coverage .

TPT18 In addition to supporting CC and DC Outside coverage , And support MCDC Cover , It is easier to achieve the desired coverage .

For example, in the model OR modular , If it is necessary to meet MCDC, The following conditions must be included ：

chart 4 In the model Or structure

1, All inputs are False;
2, One input is True, The rest are False;

stay TPT18 in , The following structures can be analyzed , And automatically generate test cases according to this structure .

Four 、 New code coverage statistics tool ——TPT Coverage

TPT When calculating coverage , Offers a variety of options , During the test, it can be decided according to its own situation .

In the model phase , You can call Targetlink、CTC++ for Targetlink and Simulink V&V Statistical coverage .

In the code phase , except CTC++ and GNU gcov Outside , It also provides TPT Coverage Statistical coverage .

5、 ... and 、 Enrich MALTAB Platform functions

1) MATLAB/Simulink Platform Accelerated operation mode

You can imagine that the data of a test case after running reaches nearly 10G Do you ？

A huge amount of data means one word —— slow , And it's super slow .

Now? , This situation is alleviated ,TPT18 Of “MATLAB/Simulink Platform” New options “Simulation Mode”, You can use “Normal”、“Accelerator”、“Rapid Accelerator” and “Software in the loop” Mode run test , It can speed up the test running .

Tip： For a large number of test cases ,TPT Support multi-core mode to accelerate operation .

2) Detect specific system coverage

TPT18 front , If you need to analyze the coverage of a specific sub level , Other sub levels need to be commented out . however , If there is interaction before the sub level , Grounding and other commissioning are required , More complicated . Now? ,TPT18 Get rid of this worry , Because you can directly exclude sub levels that you do not want to detect .

3) Direct import Stateflow Intermediate variable

TPT18 Pre import Stateflow Intermediate variables need to be manually created and set Import Measurements, You also need to add scripts to the test platform .TPT18 Can be clicked directly “offline logging” Import , Convenient and quick .

chart 12 Import Stateflow Intermediate variable

4) Automatic generation TPT Simulink Function Handler

When... Is used in the model Simulink Function, But test target level Function Caller And Simulink Function Not at the same level , An error will be reported when running the test （ Can't find Simulink Function）.

In the face of this situation ,TPT18 Automatically generated in the test framework TPT Simulink Function Handler.

6、 ... and 、 Ways to enrich a given excitation signal （TPT Built in functions ）

TPT18 The given mode of excitation signal is added , for example ：TPT.impulse()、TPT.step()、TPT.sinwave() etc. , It is more convenient to realize the desired signal .

chart 14 TPT Built in functions

7、 ... and 、 Batch Runner Interface and function update

When there is more than one TPT The project needs to run , have access to Batch Runner Running at the same time .

stay TPT18 in , Updated interface , The following steps are added ：

• TPT API-script
• Execute Tests
• Generate Testframe
• Generate Overview RePort

Support the following platforms to generate test frameworks ：

• AUTOSAR
• C/C++
• MATLAB
• [email protected]
• ASCET

8、 ... and 、 ASAM XiL And Vector Related updates

1) Expanded ASAM XiL Support

Added... To the service items ASAM XiL Diag Port, It can be used directly in the test case DTC To operate , as follows ：

• Read DTCs
• Clear DTCs
• Read/Write Values
• Execute Services
  

chart 16 Added service steps

2) Support import DBC Enumerating type signals in

stay DBC If... Is defined and associated in Value Table,TPT18 Support import .

chart 17 Import enumeration

3) XCP Communication control

Not only can you control before the test case is executed XCP Communications , And it can also be controlled in the test case , Easy to test .
