Viewing waveforms
329
5 From the PSpice menu, choose Run to start the
simulation.
One Probe window is displayed in monitor mode.
6 Do one of the following to select the waveforms to be
monitored:
• From PSpice’s Trace menu, choose Add, and enter
one or more trace expressions.
• From Capture’s PSpice menu, point to Markers,
then choose and place one or more markers.
The Probe window monitors the waveforms for as
long as the most recent data section is being written.
After that data section is finished, the window
changes to manual mode. To see the full set of runs,
you must update the display by using the Add Trace
command under the Trace menu.
Configuring update intervals
You can define the frequency at which PSpice updates the
waveform display as follows:
• At fixed time intervals (every n sec)
• According to the percentage of simulation completed
(every n %), where n is user-defined
The default setting (Auto) updates traces each time PSpice
gets new data from a simulation.
To change the update interval
1 From the Tools menu, choose Options.
2 In the Auto-Update Interval frame, choose the interval
type (sec or %), then type the interval in the text box.
Interacting with waveform analysis during
simulation
The functions that change the x-axis domain (that set a
new x-axis variable) can not be accessed while the
simulation is running. If you have enabled the display of
