<li><kbd>lvs_format</kbd>: This is the netlisting format attribute that is automatically selected if Xschem is set
to produce a LVS netlist (<kbd>Simulation-&gt;LVS netlist: top level is a subckt</kbd>). This means that a
symbol may have two different attributes for netlisting: <kbd>format</kbd> use dfor spice simulations and
<kbd>lvs_format</kbd> for schematic to layout (LVS) comparison. More in general the xschem command
<kbd>xschem set format my_format</kbd> will instruct xschem to use <kbd>my_format</kbd> as netlisting
rule for components that have this attribute defined. If symbols do not have the <kbd>my_format</kbd>
attribute the default fallback (<kbd>format</kbd> for spice netlist) is used.</li><br>
