I'm creating a DAC using R-string topology. The problem is that when I connect the resistors together to form the R-string, a marker appears over the metal1 at the PLUS and MINUS terminals on the rppolywo-resistors. Except at the connection to GND and VDD. I believe this is the cause of my LVS problems as well. If I highlight the nets between two resistors, all the resistors in the string start flashing. I don't understand this, because I can't see any fault in this layout.
