The Sequential model is the default process model that you use to test one UUT at a time. Use the Parallel and Batch process models to simultaneously run the same test sequence on groups of similar UUTs. Select Configure»Model Options to launch the Model Options dialog box to specify the number of test sockets in the test system.

The following table lists the process models and their respective sequence files.

Process Model Process Model Sequence File
Sequential Model <TestStand>\Components\Models\TestStandModels\SequentialModel.seq
Parallel Model <TestStand>\Components\Models\TestStandModels\ParallelModel.seq
Batch Model <TestStand>\Components\Models\TestStandModels\BatchModel.seq

You can create a custom process model, or you can modify a copy of a built-in process models.

To modify the installed process model or to create a new process model, copy all the process model files from the <TestStand>\Components\Models\TestStandModels directory to <TestStand Public>\Components\Models and make changes to the copy.

The list of search paths includes the subdirectories in the <TestStand Public>\Components directory.

When you create a custom process model, use the Model tab of the Station Options dialog box to specify the custom process model sequence file as the process model for the station.

Note Note  If you modify any process model or process model plug-in types, open and save all the process models and process model plug-ins that use the modified types to ensure you avoid a type conflict. To modify or save the process models, you must first copy all the files from the <TestStand>\Components\Models\TestStandModels directory to the <TestStand Public>\Components\Models\TestStandModels directory and modify or save the files in the <TestStand Public>\Components\Models\TestStandModels directory. The files in the <TestStand Public>\Components\Models\TestStandModels directory override the files in the <TestStand>\Components\Models\TestStandModels directory. Similarly, you must copy any process model plug-in files from the <TestStand>\Components\Models\ModelPlugins directory to the <TestStand Public>\Components\Models\ModelPlugins directory before modifying the files.
