Note
You should not confuse the default labels XBITS, X_lower, and
X_upper with the probe signal groups xbits, x_lower, and x_upper.
The command
gives probe signal "0" the label CLK and uses a positive polarity as
logical true.
Modifying Label Definitions
The "modify" command retrieves the command used to define a
particular label. Once the definition is returned to the command
line, you can use the command line editing features to modify the
label definition.
Deleting Labels
The "delete" command can be used to delete all labels, or
individual labels, that are not used in any other specification.
The command
deletes the default label "X_upper" from the format specification.
Renaming Labels
The "rename" command allows you to change a label name.
The command
renames the label "CLK" to "clock".
define CLK xbits_bit 0 logic_polarity
positive_true <RETURN>
delete X_upper
<RETURN>
rename CLK to clock <RETURN>
