R1909_Mega328 IN THE SUBCIRCUIT

In example 286, if I replace the controller subcircuit with its mega328 primitive and load the firmware, the OLED works but the C0 (A0) input does not support analog values. With UNO_LS it works ok and on T1709 (Reference-version) it fails too with the primitive component.

Tell me something please.

I think you should connect a 5V input to A+.

It is well connected because it works, let's not lose the focus of this post, please: That with the subcircuits (mine and simulide's) everything works but with the primitive component (mega328 or PB) it does not.

??? I can't see anything connected to your mega328's A+ pin.

Exactly.

Correct, A+ is the AVcc pin that is used to assign the voltage in the ADC converters, not the VCC that by default is connected to 5v in simulide.
