The <kbd>@pinlist</kbd> is a special token that will be substituted with the name of the wires that
connect to symbol pins, in the order they are created in the symbol. See the

the correct pin ordering in the symbol pins will make netlist generation faster. This is important
for very big components with lot of pins, and <kbd>@pinlist</kbd> is the default when symbol is generated
automatically (<kbd>Symbol -&gt;Make symbol</kbd> menu of <kbd>&lt;Shift&gt;A</kbd> key).
<br>
The <kbd>format</kbd> attribute may contain a <kbd>@spiceprefix</kbd> string immediately preceding
(with no spaces) the <kbd>@name</kbd> attribute.. This will be substituted with
value given in instance (example: <kbd>spiceprefix=X</kbd>) but *ONLY* if
<kbd>Simulation-&gt;Use 'spiceprefix' attribute</kbd> is set.
This allows to create different netlists for simulation (example: all MOS are defined as subcircuits)
or LVS (no device subcircuits).
