Hi to everyone,
I'm an electronic engineering student, I'm trying to simulate the model in the object in transient analysis but, even if I downloaded the model you published as answer to previuos discussions, I'm still getting the problem "Node U1:U4_N24227 is floating and connected to current source G:U1:_U4_G4". I'm just trying with a DC signal. Can you help me? Maybe there is a mistake in my circuit or a problem in the model. The circuit is the following.
The simulation report is this one:
