GMW14241 DWCAN Project

1.Open MxVDev.

2.Select File-> Open->Project from the main menu.

3.Use the Open dialog to select the project file:

MxPLT Sample Project GM.mxp

4.Click Open.

5.Click Edit Harness () to start MxTransIt.

6.In MxTransIt, click on the PLT Test Manager Transform to select it and display its Properties box.

7.Click the Launch MxPLTConversionTool Verb to open the tool.

8.Select the “TestCase Generation” tab to generate Scenarios and TestCases dynamically based on selected inputs.

9.Following are the inputs for the ‘TestCases Generation’ tab of the MxPLT tool.

a.Select TestCase Definition File. Click the browse button () to select the file. Once the input test case definition file is selected, fields in the GUI (Vendor Spec, Bus Interface, Baud Rate, Comm Enable Type, DUT type, Supply voltage Range, Crank Communication) are automatically loaded. Enter the ECU response ID at Rx CAN ID.

b.DUT Type. If the DUT does not have a termination resistor, select the “No Internal Termination.” If the DUT has internal termination, select Internal Termination_120Ohms or Internal Termination_60Ohms.

c.Select the Baud Rate as per DUT type.

d.Select the Supply Voltage Range. Either“Standard” (9V to 16V) or “Extended” (6V to 26.5V).

e.Select Crank Communication. If the DUT supports communication during cranking, select the Supported option. Otherwise select “Not Supported.”

f.Enter a valid Rx CAN Id, which is received from the ECU. This Rx id is used to trigger and display the waveform.

g.Click the browse button () to select the MxVDev project folder.

10.Click the Generate TestCases button to generate Scenarios and TestCases for a specific OEM.

11.Select the Message Configuration tab.

12.Configured default messages are displayed. You can edit the messages as applicable based on the ECU under test. This message is used to wake up the DUT and to continue the ECU communication (BCM message).

Note: Default configured messages need to be deleted if ECU wakes up with Vbatt or Ignition line.

13.Click the “Save Configuration” button. Observe the “XML file successfully generated” status message.

Note:The CAN Configuration file path is the same as the selected MxV Project folder path selected in the “TestCase Generation” tab.

14.Close the Test Conversion Tool, but leave MxVDev running.

1.Open MxVDev.

2.Select File-> Open-> Project from the main menu.

3.Use the Open dialog to select the project file:

MxPLT Sample Project GM.mxp

4.Click Open.

5.The generated Scenarios and TestCases are displayed in the Project Explorer:

6.Select Tools-> Regression Test ->New.

7.Click the Add button in the Regression Command File dialog:

8.Enter User Details (Optional)  in Test Info panel. Click Next.

9.Click Next in Regression Output Wizard.

10. Click Next in Distribution List.

11. Click Next in Execution Options.

12. In Scenario Query Builder, expand the tree for the NoInternalTermination folder. Select a Scenario (for example:"4.1.1.1 RecessiveOutputVoltageLevels.mxs") and click Next.

13. Click Finish to open the Save Regression Script dialog:

14. Save the Regression Script File (.mxreg).

15. Click the Close and Run button in the Regression Command File dialog:

The Regression Test Progress window shows the progress and pass/fail information of Regression Test for the selected Scenario.

After completion of the Regression Test, the report is automatically displayed.
