@Tim Edwards I was trying to LVS my design. These resistors caused my LVS to fail. I have deleted the example project blocks already. I'm just wondering whether these resistors should also be deleted from the same user_analog_project. Thanks for the clarification.

Those resistors are metal resistors needed to split a single metal net into two differently named nets. You would need the metal resistor in both the layout and the schematic to make the LVS work.

@Tim Edwards thank you for the information. I apologize but I’m not sure what it means to split a single metal into two differently named nets. What is the application of such a technique?

Precisely for the reason that is shown in your screenshot. Several pins have been tied off to various power rails, but if you connect them directly in the layout or the schematic, then they get shorted, and one of the pins disappears. If you cut the connection with a metal resistor (which is just a normal piece of metal, just identified as a resistor), then the two nets don't get merged. The power supply remains on one side and the pin on the other.

@Tim Edwards thanks once again. I believe I understand now. If I do not wish to short the IO pins to my power/gnd rails, I suppose I can just remove these resistors?
t
Yes.

Thanks @Tim Edwards!
