Simulator Command Reference ModelSim EE/PLUS Reference Manual
down | up
The
down | up
command searches for signal transitions or values in the specified
List window. It executes the search on signals currently selected in the window,
starting at the time of the active cursor. A condition to search for may also be
identified by an expression using the -
expr
command option. The active cursor
moves to the found location.
Use this command to move to consecutive transitions or to find the time at which
a signal takes on a particular value, or an expression of multiple signals evaluates
to true. Use the mouse to select the desired signal and click on the desired starting
location using the left mouse button. Then issue the
down | up
command. (The
seetime
command (p366) can initially position the cursor from the command line,
if desired.)
Returns: <number_found> <new_time> <new_delta>
Syntax
down/up
[-window <wname>] [-expr {<expression>}] [-noglitch]
[-value <sig_value>] [<n>]
Arguments
-window <wname>
Use this option to specify an instance of the List window that is not the default. Optional.
Otherwise, the default List window is used. Use the
view
command (p388) to change the
default window.
-expr {<expression>}
The List window will be searched until the expression evaluates to a boolean true condition.
Optional. The expression may involve more than one signal, but is limited to signals that
have been logged in the referenced List window. A signal may be specified either by its full
path or by the shortcut label displayed in the List window.
See "GUI_expression_format" (p236) for the format of the expression. The
expression must be placed within curly braces.
-noglitch
Specifies that delta-width glitches are to be ignored. Optional.
-value <sig_value>
Specify a value of the signal to match. Optional. Must be specified in the same radix that
