Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
In modelcards, that are typical for SPICE3, the so called technology parameters are stored. These parameters are usually set for more than one semiconductor device in a circuit, e.g., the temperature of a whole electrical circuit.
