<p>The <b>Spice</b> format was developped at the University of California, Berkeley. This parser/driver consists in a subset of SPICE3 netlist format. (see <a href="http://en.wikipedia.org/wiki/SPICE">http://en.wikipedia.org/wiki/SPICE</a> for more informations).<br />

Stand alone database structure</h1>
|
|
<p>The database consists in several objects:</p><ul>
|
|
<li><a class="el" href="class_s_p_i_c_e_1_1_circuit.html">SPICE::Circuit</a></li>
|
|
<li><a class="el" href="class_s_p_i_c_e_1_1_spice_exception.html">SPICE::SpiceException</a></li>
|
|
<li><a class="el" href="class_s_p_i_c_e_1_1_subckt.html">SPICE::Subckt</a></li>
|
|
<li><a class="el" href="class_s_p_i_c_e_1_1_instance.html">SPICE::Instance</a></li>
|
|
<li><a class="el" href="class_s_p_i_c_e_1_1_mosfet.html">SPICE::Mosfet</a></li>
|
|
<li><a class="el" href="class_s_p_i_c_e_1_1_capacitor.html">SPICE::Capacitor</a></li>
|
|
<li><a class="el" href="class_s_p_i_c_e_1_1_resistor.html">SPICE::Resistor</a></li>
|
|
<li><a class="el" href="class_s_p_i_c_e_1_1_source.html">SPICE::Source</a></li>
|
|
<li><a class="el" href="class_s_p_i_c_e_1_1_voltage.html">SPICE::Voltage</a></li>
|
|
<li><a class="el" href="class_s_p_i_c_e_1_1_current.html">SPICE::Current</a></li>
|
|
</ul>

<h2><a class="anchor" id="spiceParser"></a>
|
|
Using the parser</h2>
|
|
<p>Simply load an Spice netlist file using the static function SPICE::Circuit::readFromFile().</p>
|
|
<h2><a class="anchor" id="spiceDriver"></a>
|
|
Using the driver</h2>
|
|
<p>Using the driver is very simple, user has to create a <a class="el" href="class_s_p_i_c_e_1_1_circuit.html">SPICE::Circuit</a> object and simply add others Spice objects like <a class="el" href="class_s_p_i_c_e_1_1_subckt.html">SPICE::Subckt</a> or <a class="el" href="class_s_p_i_c_e_1_1_instance.html">SPICE::Instance</a> to it. Includes, libraries and parameters can also be added to <a class="el" href="class_s_p_i_c_e_1_1_circuit.html">SPICE::Circuit</a>. Finally use the SPICE::Circuit::writeToFile() method to dump the database to file.</p>

<p>As said is the global presentation, VLSI SAPD project provides C++ libraries and Python modules for each supported format. In this section we present simple code examples to parse and drive a SPICE file using C++ or Python.
