Device Window
The Device Window displays a graphical representation of the physical device. You can close it and open it with the menu item View > Windows > Device, or with the 
button on the View Toolbar.
You can select and filter any set of components within the Device Window. To view individual components in the Device Window, press Ctrl+Alt, and left-click on the component. The Filter PCB Nets button 
allows you to filter out PCB nets in the Device view, useful when unravelling.
| Note | |
|
PCB signals are filtered only if they are on the signal list. PCB nets still show up in the Signals list, even though they are turned off in the Device Window. |

You can also change the active FPGA by double-clicking directly from the Device Window (or from the Project Window).
You can view the Top, Bottom, or Both Sides of a device. To switch between the views, select from the View > Device menu options, Top View, Bottom View, or Both Sides View.
To rotate the view of a device and its layout, click View > Device > Rotate View, or right-click on the device, and select the required rotation (possible values are 0, 90, 180, and 270 degrees).
Right-click in the Device Window and select Rotate View by PCB Layout to switch to a PADS view format. When an active device can be rotated on the board, this option allows you to rotate the view of the entire board in the device window. When the Rotate View by PCB Layout option is turned off, the device window displays the FPGA and its layout with the same rotation established in a PADS.
To enable the display of differential pins, choose View > Device > Show Differential Pairs option from the menu. The differential pairs are then connected with red lines (by default).
