CHAPTER 1

Models and Subcircuits

Resistors, capacitors, inductors, diodes, and transistors are described in Multisim by a model. Other devices are rather described by a subcircuit.

A model is a description of the device by using its defining equations. Thus, a model can be built for any device whose equations are available from a theoretical analysis of its behavior and construction. Diodes and transistors are examples of circuit elements described by a model.

A subcircuit is a smaller circuit which can represent a set of specific properties of a larger circuit. Operational amplifiers and digital circuits such as flip-flops and gates are examples of circuits defined by subcircuits. A subcircuit is the equivalent of a method in object oriented ...
