Use the Pin View pane during debugging to interactively view and modify the current state of the pin driver, active load, comparators, PPMU, and NI-DCPower instrument settings for a single pin at a time in the active instrument session.

Note You must install the NI-DCPower driver to access NI-DCPower-related functionality in the Digital Pattern Editor.

The pane displays by default when you create or open a project. Click the collapse Pin View Pane Collapse Arrows or expand Pin View Pane Expand Arrows arrows or hover over the Pin View Pane icon Pin View Pane Icon when the pane is collapsed to toggle the display of the pane. You can also select Instruments » Pin View or View » Pin View to display the Pin View pane.

Changes you make in the Pin View pane apply only to the currently connected digital pattern instruments. You must manually make changes in the levels and timing documents if you want the changes to take effect the next time you burst a pattern. The pane reflects the changes you make in levels and time sets when you reapply levels and timing values on the instrument.

Note The Pin View pane and System View display a yellow warning icon to indicate measurements that are not up to date when the digital pattern editor is connected to existing instrument sessions and an instrument session owner, typically a test program application, is actively using the instrument session. Click the icon to take control of the instrument and acquire new measurement values in the background. The warning icon returns when the instrument session owner actively uses the instrument sessions again.

Configuring the Pin View Pane

Use the Site drop-down menu to select a site for this operation. Select System to view the system pins in the Pin control. When you remove the checkmark from the Pattern Burst checkbox of a site in the Sites dialog box, rather than disabling it, you can still view the site in the System View and modify pins in the site in the Pin View or System View pane, but bursting the pattern has no effect on the site.

Use the Pin control to select the pin in the pin and channel map for which you want to view or modify settings. Use the tooltip to display the instrument and channel that correspond to the pin. Select System in the Site drop-down menu to view the system pins in the Pin control menu. Click the switch icon , when available, to connect or disconnect the pin.

Use the expander buttons to expand or collapse each section in the pane. The pane dims the sections that are not active. Refer to the Related reference section at the end of this topic for a link to more information about each section.

A green icon Green Icon next to the Drive section indicates that the digital pattern instrument is in digital mode for the current pin when connected. A green icon next to the PPMU or DCPower section indicates that the PPMU or the NI-DCPower instrument is forcing a voltage or a current.

You can drag a document by its tab away from the main workspace window and drop the document without highlighting a docking guide location to detach the document from the main workspace and create a new instance of the application window. All instances of the application window refer to the same project file and share the same state. Using this technique, you can display the Pin View pane in each instance of the application to debug multiple pins at the same time. Selecting View » Reset Workspace in a window in this case closes all the other windows.
