Interactive Window
The individual options are separated by commas, and the entire
button definition is terminated with a semicolon.
Selection Substitution
A button definition may contain a command that includes a $*. When
you execute the button, this special string is replaced with the
currently selected text. For example, the button definition file may
specify the command $display($*) to select a signal and click the
button. If you select top.m0.a then click the button, the command
$display(top.m0.a) is sent to the simulator.
Note:
To help distinguish between normal buttons and the buttons that
have selection substitution, it is recommended that all special
buttons have a special foreground color. The default button file
shipped with this product sets the foreground color to khaki for
emphasis.
