Ah, I have just asked my professor, and she told me that I had to put a Zero Voltage at the point where I want to set as controlled current, so that I can use I = 4*I(v_ref) and it worked. Thanks for your help.

@ĐỨCNGUYỄNHUỲNH The moment you're using it with an equal, =, it's internally transformed into a behavioural source. The same is true for G or E sources with vallue=.... This can be verified by viewing the extended netlist. If the relation is linear (as ThePhoton says at the end), you're much better off using F (or H) sources than behavioural ones.

Thanks you, it's worked. By the way, is it possible to use current through other elements as a control current? From wiki, it said that you have to set a Current through voltage source to controlled F element.I set it as 'F1 0 a B1 4', it's worked. I tried to change it into F1 0 a value={4*I(R1)} and then the result is as above.
