<p>Create the AutoContact directly anchored on the Component (terminal). Three cases are manageds:</p><ol type="1">
<li><b>Ordinary (non-punctual) <code>METAL1</code> terminal</b>: an AutoContactTerminal is anchored on the RoutingPad.</li>
<li><b>Punctual <code>METAL1</code> terminal</b>, the access must never be blocked by other routing. To ensure it, we create a fixed AutoSegment (anchored on two AutoContactTerminal) to cover it. The <em>normal</em> AutoContactTerminal is also created.</li>
<li><b>non <code>METAL1</code> terminal</b>, as for the punctual <code>METAL1</code>, a fixed protection is added over the RoutingPad. If we access horizontally a vertical RoutingPad or vertically an horizontal one, an extra AutoContactTerminal is added (to allow is displacement along the RoutingPad).</li>
</ol>
<p>To avoid creating a fixed protection over a RoutingPad multiple times, the RoutingPad and it's associated protection is stored in a static <code>map</code> : <code>__routingPadAutoSegments</code>.</p>
<p>Conversely, because an AutoContactTerminal can only be connected to one segment, each time this function is called a new terminal will be created (or maybe two in case of non-punctual terminals). If only one AutoContact is requested, it is created centered on the RoutingPad. The initial position of AutoContact <em>do not prevent them to move afterwards</em>, even those created on source/target on a non-punctual RoutingPad.</p>
<dl class="section user"><dt>Remark: For clarity we describe the layer management of this function in term</dt><dd>of <code>METAL</code>, but it is the RoutingGauge depth which is actually used.</dd></dl>

<p>The Component <code>rp</code> is a RoutingPad which belongs to a pad cell. This case occurs when we are routing a complete chip. This method build, from the <code>rp</code> a stack of articulated punctual segments and contacts to reach the default H/V routing layers (usually <code>METAL2</code> &amp; <code>METAL3</code>). This may be needed when the pad terminal is in <code>METAL5</code>, for instance.</p>
<p>The returned AutoContactTerminal is anchored on the last punctual segment build.</p>
<p>The GCell into which the AutoContactTerminal is created may be under the pads area. However, it will be right on the border of the GCell. The global router vertexes of GCell under the pad area are marked as blocked so will never be used for routing.</p>

<p>Construct a topology where there at least one global and two <code>METAL3</code> RoutingPad (assumed V).</p>
<p>In this topology, we reuse the <code>METAL3</code> RoutingPad as a feedtrough in the vertical routage. <span class="red">We assume that the most likely relative position</span> <span class="red">of the RoutingPads is to be aligned vertically</span>. Thus:</p><ul>
<li>All RoutingPads are linked two by two trough vertical staircases.</li>
<li>The south-west global wiring is attached to the bottommost RoutingPad (without vertical slack). If a misalignment is detected, then a dogleg is added.</li>
<li>The north-east global wiring is attached to the topmost RoutingPad (without vertical slack).</li>
</ul>
<p>South/west and north/south can be build independantly. Depending on the number of globals, they can consist of:</p><ul>
<li>Nothing (no south nor west).</li>
<li>An sliding AutoContact on the bottommost RoutingPad (west present).</li>
<li>An fixed AutoContact on the bottommost RoutingPad (only south present).</li>
<li>An fixed AutoContact plus a vertical plus a VTee (south &amp; west present).</li>
