(TD) 3.11 Spacers and Text Font Controls

Text objects can be placed anywhere in a diagram to annotate cycles, edges, or segments. The font and color of each text object can be changed to stress the importance of that particular text object. The fonts also support superscripts, subscripts, and bold and italic attributes so your timing diagrams can use the same names and comments that are commonly used in data books. In this section we will add a Spacer signal to the top of the timing diagram and then add a title using a text object.

Add a Spacer and drag it to the top of the diagram:

•Press the Add Spacer button to insert a spacer into the diagram. If no signals are selected the spacer will be added to the bottom of the diagram.
