Everyone knows how important it is to separate different types of GND in the project.
For example I have GNDD for my MCU and digital sensors and GNDPWR for power part and I wont to connect it to power connector whith two pins
In this case I will have only one net with the name of the first connected GND
And it’s very inconvenient to trace PCB this way
How should i connect GND and GENPWR to have two different nets?
Use a net tie (NetTie) symbol and footprint.
There are special symbol and footprints to take care of this with the current toolset. (I think these might eventually be handled natively in KiCAD, but until then this is the method.) As @eelik mentions you want to use a net tie. I did an internet search and here is the first video search result (doing exactly what you want with separated grounds):
I don’t know John’s Basement, but I might have to look through his other videos… This one was pretty good IMHO. (Though, I was disappointed that he was using netlist files to send information from EEschema to PCBNew, you can send from the schematic directly to the pcb now.)
Be careful when splitting ground. It is not really a magical tool that automatically makes your circuit better. It can actually negatively impact it if you make a mistake. A golden rule is that you can not bridge the gab between your grounds with anything (not a trace and most components should not bridge the gab either). This is because you can easily make a slot antenna by providing a path for high frequency currents over the thing that bridges the gab.
Just to reply to this. Split ground’s aren’t really recommended anymore (unless they are at different potentials).
Long gone are the days of a D-GND and an A-GND, what is key is the return currents and placement to manage this
