The plug allows to create a <strong>logical</strong> connexion bewteen a <a class="reference external" href="../../hurricane/classHurricane_1_1Net.html">Net</a> of

<p>A plug is somewhat equivalent to an <em>instance terminal</em> in others

|

<p>Therefore, a plug is related to two nets:</p>

<ol class="arabic simple">

<li>The net of the <em>master cell</em> it is linked to. Obviously that

net cannot be changed. You can access the master net with the

|
||||
<li>The net of <code class="docutils literal"><span class="pre">fulladder</span></code> the plug is connected to. This can
|
||||
be set, it is how we build the netlist. To set the net, use
|

the function <code class="docutils literal"><span class="pre">plug.setNet(</span> <span class="pre">net</span> <span class="pre">)</span></code>. It the argument is <code class="docutils literal"><span class="pre">None</span></code>,
|

the plug is <em>disconnected</em>.</li>
|

</ol>
|
||||
<p>To find the plug of an instance associated to a given net in
|

the <em>master cell</em>, use <code class="docutils literal"><span class="pre">instance.getPlug(</span> <span class="pre">masterNet</span> <span class="pre">)</span></code>.
|

The <code class="docutils literal"><span class="pre">masterNet</span></code> argument being an object of class net (not

<p>The <a class="reference external" href="../../crlcore/classCRL_1_1ToolEngine.html">ToolEngine</a> class is the base class for all tools developpeds in

<span class="sc">Coriolis</span>. In the rest of the tutorial we will use the names <code class="docutils literal"><span class="pre">tool</span></code>

|

<p>To run the placer, create the <span class="sc">Etesian</span> engine, then call the <code class="docutils literal"><span class="pre">place()</span></code>

<p>You can configure the placer in two ways:</p>

<ol class="arabic">
|

<li><p class="first">Prior to the creation of the engine, setup an abutment for the cell.
