Separate grounds in kicad

How do we given different ground in kicad?
like if I have to design a dual high converter, I need to provide different ground to high and low side
then, how do we do it?
best regards

Create 2 GND single in the schematic.

Example : GND1 - for high power ground and GND 2 - for low power ground

Then later while doing copper pour you can decide the side and the type of ground you want to use.

sir,

how do we create 2 grounds?

by selecting gnd1 and gnd2?

 

Yes, Just use the GND1 and GND2 on the schematic editor

Please share the schematic, so I can give a better answer related to your schematic.
