MOST TestCase Generator

Open MxTransIt. Select a MOST Master Transform from the toolbox then click on Launch TestCase Generator.

Step 1: Click the Load button to browse to the MOST Catalog file.

Step 2: Enter the Scenario name and click to add a Scenario for generation.

Note: The (add) button is used to add an item to a box and the button is used to remove items.

Step 3: Select the Scenario name in the Scenarios box to add all TestCases under that scenario.

Step 4: Select MOST from the “Select Test Type” drop-down list, then select the “Auto Generate Testcase” check box.

Step 5: Select the required Module Name, Fblock, and Function from the drop-down lists.

Notes:

•Select a single function or “All” from the  Select Function drop-down list to generate TestCases for the selected function or for all available functions respectively.

•TestCases cannot be automatically generated for Functions which are preceded by an asterisk (*) in the “Select Function” drop-down list.

Step 6: Enter the Step Size, Split Time, Start Value (if required), and End Value (if required), then click the Generate button.

Split time: The time interval between two transitions in a Signal. (For example: Split time = 1 means transitions are added at one second intervals.)

Step size: The value difference between two transitions in a Signal. (For example: Step size = 1 means each transition is incremented by 1 from the previous transition value.)

Start Value: You can enter a start value from which the tool starts generating transitions for the selected function. (The default is the minimum range of the function type specified in the catalog.)

End Value: You can enter an end value at which the tool stops generating transitions for the selected function. (The default is the maximum range of the function type specified in the catalog.)

Step 7: Select a TestCase to display the transitions on all its Signals in the Signals box:

Transitions are displayed in the format: <Signal name> <value>

1.Click the Load button to browse to the MOST Catalog file:

2.Enter the Scenario Name and click to add the Scenario.

Note: The (add) button is used to add an item to a box and the button is used to remove items.

3.Select the Scenario name from the Scenario list box and add TestCases. All these TestCases are included in the Scenario.

4.Select the TestCase from TestCases list box.

5.Select Wait(s) from “Select Test Type”, enter the wait time in seconds, and click to add the transition to the Signals list box. By default, the first transition starts from 0.2 sec.

6.Select MOST from “Select Test Type”.

7.Select the Module Name and Signal Type (Tx, Rx or Fb) from the drop-down lists.

8.Select the FBlock.

9.Select the Function.

10.Select the Op Type. (The Parameters list will populate.)

11.Enter the required value  for each parameter, then select the parameter.

12.Click to add the parameter to the Signals box.

Note: Tx is for MOST Transmit Driver, Rx is for MOST Receive Driver, Fb is for MOST Vnode Transform.

Wait inserts a time interval between two consecutive transitions in a Signal.

Example:

Amplifier. Tx_Amplifier_DSPMode_Set_DSPMode 2 -> Wait 1 -> Amplifier.Tx_Amplifier_DSPMode_Set_DSPMode 3

means Amplifier.Tx_Amplifier_DSPMode_Set_DSPMode transition 3 is added 1 second after transition 2.

To modify the Signal value, select the Signal in the Signals box, enter the updated value, and click Update.

The following commands are available for saving and opening TestCase files:

•Select Generate -> Excel TestCases from the menu or click to generate an Excel spreadsheet with TestCase data.

•Select File -> Save from the menu or click to save all TestCases in .mxt format.

•Select File -> Open from the menu and select an .mxt file to open all TestCases.

•Save the TestCases to an MxVDev project:

a.Select an Excel TestCase file using browse button.

b.Select an MxV Project Folder using browse button.

c.Select Generate -> MxVDev TestCases from the menu or click .

There is a limit of 1000 steps per Signal.
