I am trying to simulate a more complex circuit (BW limited current source) but on the way I was playing with the basic blocks, and the results don´t seem normal.
What I would expect is that voltage V2 should be 10k times V1, or about +80dB. What I get instead is -390dB. What am I doing wrong?

 

And I will answer myself, the expression for some reason has to containg the voltage source and not the resistor, so I=I(V1).

 

It was almost right.
That's completely correct:

I don't understand that either.
It works okay with a transient simulation, but not with an AC simulation.
Looks like some kind of bug.

It would be interesting to know if other simulators (Multisim etc) show the same effect?

I perceive such insult as a reality.And I try in formulas (expressions) not to use currents through elements.
This is the legacy Spice2, in which the current through the element could be observed only by using a zero voltage source.
Then there will be no such incident.
