84 Chapter 5—The Timing and Simulator Tools
Here are the components of the Timing window:
Displaying Signals in the Timing Window
Adding a Signal Trace
To add one or more signal traces to the Timing window,
Select any number of named signals in the schematic.
Click the Add to Timing tool ( ) or select the Add to Timing command
in the Simulation menu.
Removing a Signal Trace
To remove a trace from the Timing window,
Time Scale
Area
Located just below the Timing window’s title bar, the time scale is
used to establish the absolute timing of value changes in the trace
area. The scale is dependent upon the timing resolution (set using
the < and > buttons in the Simulator Palette). The time scale is also
used to set insertion points and selection intervals for use in editing
functions.
Trace Area This area displays simulation results and allows editing of
waveforms. Waveforms can only be modified in the future, i.e., at
times greater than the current simulation time.
Label Area Displays the list of signal names corresponding to the timing traces
at right. Traces can be repositioned by dragging them vertically in
this area. In addition, a pop–up trace menu can be displayed by
right–clicking in this area.
Horizontal
Scroll Bar
This allows you to display time to the right or left of the present
viewing area. The horizontal scroll bar is available when the
simulation is stopped, but disabled when the simulation is running.
Vertical Scroll
Bar
This will display the signal labels and their corresponding traces
above or below the ones presently displayed.
