I want to know what the electrical reference for the op-amplifier is. The output voltage range of a general op-amplifier should be relative to its power supply. But there is actually no defined input power supply for the op-amplifier in Simulink, is the electrical reference the reference ground for the entire system at this time? Will this be a problem in some complex simulation models.

I built a DAB converter that includes an active filter. The op amplifier plays an important role here, but I found that its input end is not dashed. It is confusing.I want to know what the electrical reference for the op-amplifier is. The output voltage range of a general op-amplifier should be relative to its power supply.
