Chapter 13 Analyzing waveforms
330
waveforms during simulation and wish to reconfigure the
x-axis settings (as explained below), you must wait until
the simulation run has finished.
The following table shows how to enable the functions
that change the x-axis domain.
Pausing a simulation and viewing waveforms
You can pause a simulation to analyze waveforms before
the simulation is finished. After you pause the simulation,
you can either resume the simulation or end it.
To pause a simulation
1 From PSpice’s Simulation menu, choose Pause.
2 In the Probe window, view the waveforms generated
before you paused the simulation.
