Add advanced markers on the schematic load/output to plot bode plot directly. They can be accessed by option PSpice from toolbar > Markers > advanced > db magnitude of voltage, phase magnitude of voltage and others
Below is a random example ckt. showing advanced markers placed on the schematic,
Now you should be able to make gain and phase margin measurments for your design
Also, from the graph you may see that phase is plotted on a different Y-axis. Go to plot > Add Y-axis after plotting the graph for gain, and then plot the phase graph
A DC-C regulator has a feedback voltage divier circuit which used to compare with a reference voltage. Add an AC injection source from the output voltage to the top resistor. Use dB Magnitude Probe to measure the Gain between the two nodes of the AC injection source. Use dB Phase Probe to measure the Phase across the AC injection source
Hi Vignesh,
Try this after running your AC simulation,
