This Package contains the basic components of the SPICE3 models. The first letter of the
name of the component shows the SPICE name, e.g., R_Resistor: R is the SPICE-name of the component
resistor which is used in SPICE-Netlists.

Ground of an electrical circuit. The potential at the ground node is zero. Every electrical circuit has to contain at least one ground object.
SPICE does not have an element for the ground node (mass). In SPICE netlists the ground is specified by the node number 0. This Modelica SPICE library demands to describe the ground node by this ground element.

The linear voltage-controlled voltage source is a TwoPort. The right port voltage at pin p2 (=p2.v) is controlled by the left port voltage at pin p1 (=p1.v) via
p2.v = p1.v * gain.
The left port current is zero. Any voltage gain can be chosen.

The linear current-controlled voltage source is a TwoPort. The "right" port voltage at pin 2 (=p2.v) is controlled by the "left" port current at pin p1(=p1.i) via
p2.v = p1.i * transResistance.
The controlling port voltage is zero. Any transResistance can be chosen.

The voltage source VNAM has the two nodes NV+ and NV-:

On this way the current, that flows through the voltage source VNAM, flows through the CCV.
