See “How can I join two nets together on a Schematic and then on the PCB without creating an ERC and a DRC violation, respectively?

Both of these methods (“virtual short” component; real 0 Ohm resistor component) are used when you want DRC to make sure 2 nets are shorted together at one and only one place. For example, star grounds, the single-point connection between AGND and DGND. They can also help remind us to put the termination resistors at the correct end of a trace. Or connecting only at the 2 “ends” of a planar transformer. microwave filter designers seem to really like the “virtual short” component. “There are a number of advantages to [placing a zero Ohm resistor]. At prototype stage you can experiment with the options, such as a direct short between the two grounds, or a resistor, or an inductor. I commonly see a 10 ohm resistor used for this purpose. Another advantage is simplicity. You already know how to do this one. … It is *
