The Highlighting option allows you to set persistent colors on designated macros, nets,
or both across the system.
To set a highlight, go to the Logical Object Browser or the Net Object
Browser, select one or more macros and/or components, and click the pencil
icon as shown in the following toolbar.Figure 9-32. Pencil and Eraser
Icons
When you set a highlight, all selected macros, ports, and/or nets in the
design are marked with the selected color. The selected color appears in the
left object browser tree. The following figure shows the left Main Object
Browser with the logical tree displayed. To select both components, click one
component, hold down the Ctrl key and click the other component.

Highlighting Shown in the Object Browser Tree
The color remains until you select one of the two middle eraser icons:
The left eraser icon
removes all highlights.
The right eraser icon
removes highlights only from selected items.
To set the highlights, use the Current
Highlight check box from the Design Settings docking
window. Below this check box are an Auto Rotate check
box, along with eight Highlight check boxes and radio
buttons.
Use the
Highlight check boxes to enable or disable a
highlight. Separate check boxes are provided for macros and nets.
Use the
Highlight radio buttons to designate which
highlight is active.
Note: You cannot disable
the active highlight.

Docking Window
Clicking the colored box next to each check box allows you to select a color
for that macro or net.
The following figure shows an example of the
results when all options under Nets are exposed.Figure 9-35. Example of Exposing
All Nets
If Net Settings is not checked, all nets in
the system, except cross-probe nets, are disabled. All options subordinate to
that option are marked with a gray box to show that the option is not used. If
Show Nets for Highlighted Macros is not checked, all
net options inside the currently highlighted net selections are disabled. To
restore the color of these options, check the individual options. If you check
Show Nets for Highlighted Macros, the individual
settings in the highlight settings area determine whether nets will be
drawn.
Note: If you enable
Auto Rotate and Net under
Auto Rotate, and then uncheck the check box in
the Net color selection, the net color in the Net
view is not consistent with that of the Planner.
The
Consolidate Globals option converts the raw clock display
with globals connected to locals as if the sum of the local nets and the global nets
are the same net. This is for display purposes only.
The bottom three options in
the Design Settings docking window work with groups of macros and ports for
which you consider net lines as a single entity:
Show Interior
Nets for Selected/Highlighted Macros shows lines that
connect two different macros in the group.
Show Input
Nets for Selected/Highlighted Macros shows lines that
connect an output port of an exterior macro to one or more input pins in
the group.
Show Driver
Nets for Selected/Highlighted Macros shows drivers in
the group that connect with an exterior macro.
