The linear current-controlled current source is a TwoPort. The "right" port current at pin 2 (=p2.i) is controlled by the "left" port current at pin p1(=p1.i) via
p2.i = p1.i * gain.
The controlling port voltage is zero. Any current gain can be chosen.
The corresponding SPICE description
Fname N+ N- VNAM VALUE
is translated to Modelica:
    Fname -> Spice3.Basic.F_CCC Fname
    (Fname is the name of the Modelica instance)
    N+ -> p2.i
    N- -> n2.i  
The voltage source VNAM has the two nodes NV+ and NV-:
VNAM NV+ NV- VALUE_V
The current through VNAM hast to be led through the CCC.
Therefore VNAM has to be disconnected and an additional
node NV_AD has to be added.
    NV_AD -> p1.i
    NV- -> n1.i
On this way the current, that flows through the voltage source VNAM, flows through the CCC.
VALUE -> gain
