Assigning Signals to Pins Using Drag and Drop

To assign signals to pins with drag and drop, use the following procedure:

1. Select the signals that are to be assigned in the Signal List. Selecting a bus will assign pins to all bus elements.

2. Click the selected signals, and drag them to the Pins List or Device Window.

Pins that are to be assigned are highlighted in yellow. In the Pins List, the signal names are displayed in the Signal column.

When more than one signal is being dragged onto the device, pins are highlighted in horizontal rows. The horizontal row may be toggled to a vertical column by holding down the CTRL key while dragging.

To restrict the assignment to one power bank only, hold down the ALT key while dragging.

Existing assignments are preserved, since signals that already have pins assigned to them are not considered for assignment. To force changes in existing assignments, hold down the SHIFT key while dragging. New assignments are then given independently of the existing assignments. Conflicting assignments will be removed.

3. Drop the dragged signals to perform the assignments.

If too many signals are selected, as many signals as pins available will be assigned.

Assignments using drag and drop may also be performed in the opposite direction, by dragging pins in the Pins List or the Device Window to the Signals List. Signals that are to be assigned to are highlighted in yellow, and holding down the SHIFT key overwrites existing assignments.
