<p><span class="sc">Alliance</span> is a complete toolchain for <span class="sc">vlsi</span> design. It provides a <span class="sc">vhdl</span> compiler
|
||
|
|
and simulator, logic synthetiser, automatic place & route and portable <span class="sc">cmos</span>
|
||
|
|
library. It has been in used in research projects such as the 875K transistors
|
||
|
|
<span class="sc">StaCS</span> superscalar microprocessor or the 400K transistors <span class="sc">ieee</span> gigabit <span class="sc">hsl</span>
|
||
|
|
router. It has been actively developped during the 1990-2000 years and is maintained
|
||
|
|
since. It's practical limit for one standard cell block (flat) is about 10K gates,
|
||
|
|
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 & 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>

<h3><a class="toc-backref" href="#id3">Design Flow</a></h3>

<p>We are also upgrading the complete design flow by replacing <span class="sc">Alliance</span> obsoleting
|

tools by more advanced <span class="sc">foss</span> alternatives:</p>

<h2><a class="toc-backref" href="#id4">Design & Features of <span class="sc">Coriolis</span></a></h2>
|
||
|
|
<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++ & 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
