<h4>Description<a class="headerlink" href="#description" title="Permalink to this headline">¶</a></h4>
|
||
<p><em>Stratus</em> is a set of <em>Python</em> methods/functions dedicated to
|
||
procedural generation purposes. From a user point of view, <em>Stratus</em> is
|
||
a circuit’s description language that allows <em>Python</em> programming flow
|
||
control, variable use, and specialized functions in order to handle vlsi
|
||
objects.</p>
|
||
<p>Based upon the <em>Hurricane</em> data structures, the <em>Stratus</em> language gives
|
||
the user the ability to describe netlist and layout views.</p>

||
<div class="section" id="configuration">
|
||
<h4>Configuration<a class="headerlink" href="#configuration" title="Permalink to this headline">¶</a></h4>
|
||
<p>A configuration file can be used to direct the generation process of
|
||
Stratus. With this file, the user can choose the output format (vst,
|
||
vhdl...), the simulator (asimut, ghdl...), the standard cell library...
|
||
This configuration file named <code class="docutils literal"><span class="pre">.st_config.py</span></code> must be placed either in
|
||
the HOME directory or in the current directory. This file contains a set
|
||
of variables used in the process generation of Stratus, as for example :</p>
|
||
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="nb">format</span> <span class="o">=</span> <span class="s1">'vhdl'</span>
|
||
<span class="n">simulator</span> <span class="o">=</span> <span class="s1">'ghdl'</span>
|
||
</pre></div>
|
||
</div>
|
||
<p>The default configuration of Stratus uses the Alliance CAD system, ie
|
||
<code class="docutils literal"><span class="pre">'vst'</span></code> as <code class="docutils literal"><span class="pre">format</span></code> and <code class="docutils literal"><span class="pre">'asimut'</span></code> as <code class="docutils literal"><span class="pre">simulator</span></code>.</p>

<h4>Description of a cell<a class="headerlink" href="#description-of-a-cell" title="Permalink to this headline">¶</a></h4>
|
||
<p>A cell is a hierachical structural description of a circuit in terms
|
||
of ports (I/Os), signals (nets) and instances.</p>
|
||
<p>The description of a cell is done by creating a new class, derivating

<ul class="simple">

has to be instantiated. The different methods described before have to

<p>Then different methods are provided :</p>

<ul class="simple">

<li>no argument : creation of a netlist file</li>

<li>Method <code class="docutils literal"><span class="pre">Testbench</span></code> : Creates the testbench of the cell using the

of the <code class="docutils literal"><span class="pre">format</span></code> variable given in the configuration file</li>

<h4>Description<a class="headerlink" href="#id151" title="Permalink to this headline">¶</a></h4>
|
||
<p>This method is a method of net. The net which this method is applied
|
||
to is the command of the shifter, it’s the one which defines the number
|
||
of bits to shift. The net given as parameter is the input net. The other
|
||
arguments set the different patameters. The method returns a net : the
|
||
output net.
|
||
Note that it is possible to change the generator instanciated with the
|
||
<code class="docutils literal"><span class="pre">SetShift</span></code> method.</p>
