The symbol "/" is commonly used to designate an inverted logic signal, "#" is another candidate. But unfortunately, it's not compatible with high level languages. In the present schematic "reset" and "/reset" are different signals. I suggest "nreset" as a HDL compatible signal name.

So what u say is I can use, for example, one label RST and on other wire /RST and in harware I will see a not gate, am I right?

You won't "see" a not gate without placing a symbol in the schematic.

"RST" and "/RST" are upto us,notation.As FvM said for better understanding and standardized notation it should be "nRST" or "RST_n". 

They are just label name.That doesn't mean "not gate" will be automatically produced because of this name..You need to give specifically "NOT" gate in your schematic and then for understanding you can give those types of labels.
