Migrating doc from Sphinx towards Pelican. * Change: In documentation, now generate the overall documentation using Pelican instead of Sphinx. This allows to have an unified approach between the coriolis.lip6.fr website and the local documentation. So we keep using "only" two doc generators: doxygen & Pelican.

above that limit you would need to use hierarchy and manually build a floorplan.
<span class="sc">Alliance</span> is entirely written in C.</p>
<p><span class="sc">Coriolis</span> was started in the year 2000 as a replacement for the place &amp; route stage
of <span class="sc">Alliance</span>. As such it is able to handle standard cells block (flat) of at least 150K
gates. It was later extended to support analog design re-implementing the methodology
introduced by the <span class="sc">cian</span> team of <span class="sc">lip6</span> / <span class="sc">su</span> in <span class="sc">cairo</span> / <span class="sc">cairo+</span>. The tools have
been designed from the ground up to support digital only, analog only or mixed circuits.
<span class="sc">Coriolis</span> is written in a mix of C++ and <span class="sc">Python</span>.</p>

<p>The <span class="sc">Coriolis</span> toolchain is build upon the <span class="sc">Hurricane</span> database.</p>
<ul class="simple">
<li><strong>Tool Integration.</strong> To better manages the challenges arising in the
increasingly bigger designs, the various tools have to work together
as a whole, in a tight integration at runtime. The <span class="sc">Hurricane</span> database
has been develop to address this problem and as a results, all <span class="sc">Coriolis</span>
tools are built upon it and can communicate through that core database.</li>
<li><strong>Deterministic.</strong> The database and the tools are completely deterministics.
Two runs in <em>exactly</em> the same context gives the same result.</li>
<li><strong>C++ &amp; Python.</strong> The <span class="sc">Hurricane</span> database and all tools are fully exported
in <span class="sc">Python</span> providing a seamless integration. The whole toolchain is build
as a mix of C++ for computational intensive part and <span class="sc">Python</span> scripts for
everything else. There is not even a binary, the main program <em>is</em> a
<span class="sc">Python</span> script and can be rewritten in any way you like.</li>
<li><strong>Graphic Interface.</strong> <span class="sc">Hurricane</span> also come with a graphical interface
allowing to display, explore or check your design. The graphic interface
can be extended (in C++) do display any custom overlay.</li>
<li><strong>Symbolic Layout.</strong> For digital part of the designs, we use a symbolic
layer approach. Note that <span class="sc">Coriolis</span> can make digital designs using real
technology, but it's a largely untested feature yet.</li>
<li><strong>Analog Design.</strong> A complete user-guided methodology for designing analog
circuits is available. It is fully integrated in all the tools and will
allow mixed design in the near future.</li>

<p><span class="sc">Alliance</span> / <span class="sc">Coriolis</span> tools, at the time being, are not suitable for deep submicron
technological nodes (below 130nm / 180nm).</p>
<p>For portability across foundries, technological nodes and freedom from fondries <span class="sc">nda</span>,
<span class="sc">Alliance</span> / <span class="sc">Coriolis</span> rely on <em>portable</em> layout (or <em>scalable</em> layout, or <em>symbolic</em> layout).
To produce a valid <span class="sc">gds</span> file, you would need to use the <span class="cb">s2r</span> translation tool which
needs a configuration file suited for the target technology, and <em>that</em> file is under
<span class="sc">nda</span>. So, either should be written by you, or given to you through services like
