<h2>Diffusion MOS transistor extractor (<a href="/about/drc_ref_global.xml#dmos3">dmos3</a> and <a href="/about/drc_ref_global.xml#dmos4">dmos4</a>)</h2>
<p>
DMOS devices are basically identical to MOS devices, but for those source and drain are
separated. This is often the case for diffusion MOS transistory, hence this name.
</p>
<p>
DMOS and MOS devices share the same device class. DMOS devices are configured
such that source and drain cannot be swapped. The netlist compare will report
source/drain swapping as errors for such devices.
</p>
<p>
DMOS transistors are recognized by their gate ("G" input), source ("S" input) and drain ("D" input)
regions. Source and drain needs to be separated from the gate shape. The touching edges of gate and
source/drain regions define the width of the device, the perpendicular dimension the gate length.
The terminal output layers for DMOS devices are the same than for MOS devices: "tS" for source,
"tD" for drain, "tG" for gate, "tB" for bulk (4-terminal version).
