Description</A>
</H3>
<P>
Instantiation of an instance. The type of the instance is given by the <code>model</code> parameter. The connexions are made thanks to the <code>connectmap</code> parameters.
<P>
<H3><A NAME="SECTION00032400000000000000">
Parameters</A>
</H3>
<P>
<UL>
<LI><code>Model</code> : Name of the mastercell of the instance to create (mandatory argument)
</LI>
<LI><code>name</code> : Name of the instance (optional)
<BR>
When this argument is not defined, the instance has a name created by default. This argument is usefull when one wants to create a layout as well. Indeed, the placement of the instances is much easier when the conceptor has chosen himself the name f the instances.&lt;/para&gt;
</LI>
<LI><code>connectmap</code> : Connexions in order to make the netlist
<BR></LI>
</UL>
<code>param</code> and <code>map</code> are dictionnaries as shown in the example below.

Errors</A>
</H3>
<P>
Some errors may occur :
<UL>
<LI><code>Error in Inst : the model Model does not exist.</code>
<BR><code>Check CRL_CATA_LIB.</code>
<BR>
Either one has made a mistake in the name of the model, either the environment variable is not correct.
</LI>
<LI><code>Error in Inst : port does not exist in model Model.</code>
<BR>
One port in map is not correct.
</LI>
<LI><code>Error in Inst : one input net is not dimensionned.</code>
<BR>
The size of the output nets is automatically calculated bus the input nets must be dimensionned before being connected.
</LI>
