Expressions
The Expressions Dialog has a Breakpoints list, a Name field, a
reference File designator menu, a reference Scope field, a Trigger
field, an Expression field, and five action buttons.
Breakpoints
Displays the names of all expressions that have been entered and
indicates if the expression is being used for searching in the currently
active breakpoint group.
• Use the Breakpoint icon to select among the defined breakpoint
groups. Note that the breakpoint group associated with any open
window is not affected by toggling the group displayed in this
dialog.
• To display values in all fields associated with the expression,
select an expression name in the Breakpoints List. All fields of the
dialog display values associated with this expression.
• To enable searching on an expression, click left on the toggle to
the left of the expression name.
• To display expressions in the Waveform or Register Window, drag
and drop the expression name from this area to the window.
Name
Lists the name of the expression. Use Name to name or rename the
expression. Names can include any combination of alphanumeric
characters and underscores, but they must not begin with a number.
Use of short names is advised. When the expression completes a
search in the Waveform Window, the expression name is displayed
above the C1 cursor.
