Simulation and Animation
Simulator Cross-Probing
The Open As dialog box is also displayed when you double-click over a block or component
instance in a block diagram, if the instance is described by a HDL text view.
You can choose to open the view using the default view style, or as a block diagram, state
diagram, flow chart or text view. (The default view style is used if the specified view cannot be
rendered.)
These views allow limited editing but fully support the simulation cross-probing and animation
features.
Note
If you set the Always use this view style option in the dialog box, the dialog box is not
displayed and HDS attempts to always render HDL text views using the last selected
style.
You can add simulation probes to the active graphical block diagram view by using the
button in the ModelSim Wave window or by choosing Add Probe from the Debug menu in the
ModelSim Wave, List or Signals windows. Refer to “Adding and Removing Simulation Probes”
on page 411 for more information about using probes on graphical diagrams.
When you have invoked ModelSim from a HDL Designer Series tool, a
button is added to
the ModelSim toolbar and a Cause command to the Debug menu in the simulator Wave
window.
This command can be used to update all currently open animation windows to the simulation
step or event immediately preceding the time marked by the Wave window cursor for the
currently selected signal. If there is no cursor in the Wave window, the simulation time is set to
zero.
If cursor tracking is enabled in a block diagram the values displayed by simulation probes in
these views track the simulation time under the Wave window cursor. If cursor tracking is
enabled in a state diagram and an animation view is displayed, the state machine animation
tracks the cursor.
