Custom Trigger HDL  

Adding many objects to the Advanced Trigger Condition Editor can make the work space cluttered and difficult to read. To keep objects organized while you build your advanced trigger condition, use the shortcut menu and select Arrange All Objects. Alternatively, use the Zoom-Out command to fit more objects into the Advanced Trigger Condition Editor window.
