Dynamic Highlighting

By default, the software highlights objects automatically when you move your cursor over the object. This behavior is called dynamic highlighting and helps you by identifying

■Which object you will select when you press the left mouse button

■Which object will be affected by a direct manipulation command

■Which object will be affected by a command when infix is turned on

To highlight an object dynamically, do the following:

Move the cursor over the object.

The object is highlighted with a dashed line.

Note: You can turn off dynamic highlighting. Also, when a Cadence® SKILL language enterfunction is executed, the dynamic highlighting of the objects in the schematic window is turned off.

Using the Mouse to Select Objects
