Use the Connections section on the Pin Map Tab to specify mappings among pins, sites, instruments, and instrument channels. You can right-click any item in the section you want to edit and use the context menu to complete common tasks.

Choose one of the following options to add a connection to the pin map file:

  • Click <Add Connections Here> to display the Connections pane, and click the button of the connection type you want to add.
  • Right-click <Add Connections Here> and select the connection type you want to add from the context menu.

The Pin Map Editor automatically adds the connection to the Connections section. Select a connection in the Connections section to display the Connections pane, where you can edit the attributes of the connection.

You can also cut, copy, and paste instruments, or add comments in the Connections pane. Use the Comment button to specify a comment for the selected connection. Comments display beneath the connection they modify.

The Digital Pattern Editor supports the following connection types:

  • Connection — Specifies a direct connection between a DUT pin in a specific site and an instrument channel for one or more sites.
  • System Connection — Specifies a direct connection between a system pin and an instrument channel.
  • Multiplexed Connection — Specifies a multiplexed connection between the same DUT pin on multiple sites and a single instrument channel. Multiplexed connections are not natively supported in the Digital Pattern Editor.
  • Relay Connection — Specifies a connection between a site relay and a relay driver module control line for one or more sites.
  • System Relay Connection — Specifies a direct connection between a system relay and a control line of a relay drive module.

Connections Table

Select the top-level Connections section to display the Connections table, which includes a row for every possible connection that can be made with the available pins, relays, and sites. Use the View Connections for control to filter the view by pin categories, such as by all pins and relays, DUT pins and site relays by site, and system pins and relays.

The Connections table includes the following sortable columns:

  • Pin — Specifies the name of a device pin to connect to an instrument channel or the name of a relay to connect to a control line on a relay driver module.

    Refer to the specifications document for your digital pattern instrument for more information about the number of channels you can connect for each digital pattern instrument. You do not have to connect every pin in the pin map, but you might receive a warning for unconnected pins. Pin names take precedence over channel names if names are duplicated.

    Note  

    Currently, the Digital Pattern Editor does not support using system pins in patterns.

  • Site — Indicates the test site to which the connection for a particular row applies. After selecting an instrument or relay driver module for the row, you can enter a comma-separated list of site numbers to allow multiple sites to share the connection.
  • Instrument — Specifies the name of the instrument or relay driver module to connect. Select <Disconnect> to remove the association between the pin and the instrument or the relay and the relay driver module.
  • Channel — Specifies an instrument channel number to assign to the pin or a control line on a relay driver module to assign to the relay.
  • Multiplexer — If applicable, specifies the multiplexer required to create the route. Multiplexers are not natively supported in the Digital Pattern Editor.
  • Route — If applicable, specifies the multiplexer route required to connect the pin and site to the instrument and channel. Multiplexer routes are not natively supported in the Digital Pattern Editor.
