Run
button to resume the run that you interrupted. VSIM will hit
the breakpoint, as shown by an arrow in the VSIM Source window and by a message
in the Main window. Also note that the parameters and variables within the function
are displayed in the VSIM Variables window.

Click the
Step
button to single-step through the simulation. Notice that the values
change in the VSIM Variables window. You can keep clicking

Now let’s take a look at the simulation in the Wave window.
In the Wave window, you
can use cursors to:
•
probe for values
- Signal
values update whenever you
move the cursor.
•
find signal transition times
-
Click a signal edge, the cursor
displays the time.
•
measure time intervals
- Time
is displayed between two cursors.
