I made a simple R2R ADC, but in simulation, the SPDT switches I'm using as stand-ins for a digital input are behaving oddly. They don't seem correctly linked to their nets.
On successive reloads, R6P1 has shown 5V, 0V, and some value in between for no apparent reason.
I have seen similar behavior with R5 and R7's simulation. I have tried deleting and rewiring all three switches, but it just keeps failing to simulate a correct value for RxP1 in position A (0V) or B(5V).
Currently it is showing the same net as simultaneously 5V and GND, depending on which resistor I look at.
