Add Simulation Monitor Form

Signal Name specifies the names of the nets you want to monitor. You can add net names by selecting a wire, pin, or instance in the schematic or by typing the signal names. Use a space to separate multiple signal names. The following rules apply:

■If the name is not a valid name in the database, the signal is not monitored and a warning is issued.

■The system concatenates relative signal names to the scope of the design, which results in a fully scoped name being passed to the simulation database connection. For example, specifying clock results in the name current_scopeclock.

■You can specify signal names from child scopes by typing the partial scope. For example, specifying I3/clock results in the name + current_scopeI3/clock.

■Signal names preceded by a slash ( / ) do not have the scope attached. This lets you probe signals outside of the current scope. For example,

/top/I3/I4/reset results in /top/I3/I4/reset.

■The system displays in bus format the state of any signal name made up of multiple bits. The default bus radix is hexadecimal.

Format specifies how the monitor appears and which simulation information the monitor displays. The possible choices are

<state>

<time>:<state> <name>=<state>

<name>=<time>:<state>

Type specifies the type of simulation monitor.

monitor continuously displays the state of the signal and updates the display every time the current simulation time of the window changes.

display shows the state of the signal only until the command ends. When the command ends, all simulation monitors are deleted.

Bus Expansion specifies howSignal Name is interpreted.

off (default) places a monitor for each terminal name that you specify in the Signal Name field. When selected, the system resets the signal name of the pin to the full text of the name that generates the current member name.

on generates the terminal name for each bus name (specified as individual vectors) in the order specified in theSignal Name field. For example, for the nameA<0:1>, the system generates the labels A<0> and A<1>.

Placement specifies the mode you use to place monitors.

single (default) requires you to point and click to identify a monitor location.

multiple prompts you to point and click to specify the first and second monitor locations.

The system uses the distance between these two points to automatically place any remaining monitors.

Auto Placement automatically places the specified signal monitors near a pin figure that connects to a matching net name.

Add Symbol Label Form

Label specifies the label name. The system fills in this field automatically, depending on the option you select from the Label Choice cyclic field.

Font Height specifies the height of the text in user units.

Label Choice contains a list of valid label types.

Font Style specifies the font the system uses to display the label.

Label Type specifies how the system displays the label in the design. normalLabel displays the label as a text string.

NLPLabel interprets the label according to netlisting rules and displays the result.

ILLabel interprets the label as a SKILL expression and displays the result.

Justification specifies the position of the cursor with respect to the text.

Rotate turns the note text counterclockwise in 90-degree increments around the reference point.

Add Symbol Shape Form – Arc

Shape specifies a shape you can add to your design. The Add Symbol Shape form expands and contracts depending on which Shape option you select.
