Device models are composed of three formulations:
<ul><li>static,
<li>AC small-signal, and
<li>large-signal.</ul>
Each model formulation is described by its own set of equations and
variables.


<H2 align=left>Setting initial conditions</H2>

Two procedures are provided by <i>SPICE</i>Lib to specify the 
initial conditions: 
<ul><li>the <b>IC symbols</b> (see Table 2), and 
<li>the <b>IC property</b> of capacitors and inductors. </ul>
The IC property allows the user to associate the initial condition with a device,
while the IC1 and IC2 pseudocomponents allow the association to be with a node or node
pair.<br><br>

<TD>IC1</TD>
<TD>A one-pin symbol that allows you to set the initial condition on a net
for both small-signal and transient bias points.</TD></TR>

<TD>IC2</TD>
<TD>A two-pin symbol that allows you to set initial condition between two nets.</TD></TR>
