This section provides an overview of the circuit description syntax expected by the XSPICE simulator. A general understanding of circuit description syntax will be helpful to you should you encounter problems with your circuit and need to examine the simulator's error messages, or should you wish to develop your own models.

This section will introduce you to the creation of circuit description input files using the Nutmeg user interface. Note that this material is presented in an overview form. Details of circuit description syntax are given later in this chapter and in the previous chapters of this manual.
