A 0Ohm resistor is not much different from a wire link or jumper.
It should have no electrical effect, and probably will not solve your problem by itself.
There are many other aspects of circuit design and board layout that may matter,
so whatever anyone say, there may be other members with different experience,
or opposing opinions.
While connecting digital ground, analog ground and high power ground together in a single point is a sensible practice.
Doing so at the Power connector may cause problems where control signals are connected to power switching components. Especially if there are long or complicated traces between power connector and power semiconductors.
Rather than at the power connector, you may try to connect digital Vss and high current return circuits together,
close to where Gate drive signals are are connected to power semiconductors.
And if this is all around in different places, you may have problems anyway.
Optical isolators, signal transformers, or proper FET driver IC components may help.
As mentioned above, 0Ohm resistor may be used to trick circuit modelling, circuit simulation,
or board layout software by providing different names for parts of network.
It is also used to provide a link that may be removed or replaced to reconfigure a board.
It is used in SMD circuit board production,
since it is a low cost component that can be mounted by the same pick and place machine that is used for other components. And thus can be mounted without manual work.
