HP3070 TESTER

Start Board Development Begin the test development by creating or opening a board directory. To create a new board, 1    Select  File  >  New . Figure 3-2    Create a new board 2    Specify the board directory to create, and use the Browse buttons to specify the locations of the board and board_xy files. 3    Click  Create Board . To open an existing board, select  File  >  Open  to locate the file. Or select  File  >  Reopen  to select from a list of recently opened files. When you open an existing board, the window opens at the task you were working on when you last saved the board. Figure 3-3    Configuration > Start Board Development

The  Configuration  Phase defines the features and options for testing a board. Select  Configuration  in the Phases panel to perform the tasks in this phase: Start Board Development : Create or open a board file. Target Configuration : Define the configuration of the test system. Board Configuration : Modify the board options. Fixture Configuration : Modify the fixture defaults and define custom fixture components. You can create a new configuration by filling in the fields and options, or import and edit data from templates. You can also save the new configuration to templates for future use. As board test development can be done on any workstation, the software does not check that the features and options that you enable for the test are actually available on the target test system.

The ICT browser will automatically be launched whenever highlight device/nodes statements are encountered in the testplan being run. The devices/nodes in question are listed in the  Highlight  tab as shown in  Figure 2-5 . (While the testplan is running, keep the ICT Browser window in the background. The list of highlighted devices and nodes will continue to be updated as the tests are run.) From the ICT Browser window, you can press  F4  to stop the testplan and  F1  to continue running the testplan. Navigate through the tree in the  Highlight  tab to view information on the highlighted devices or nodes. In the graphics display, the selected item is highlighted accordingly.
