== Width Inference ==
Many components also accept the value <code>x</code>.  This value tells the component to chose its width based on the width of the values on its input wires.  For example:

[[File:Bit_width_inference]]

In this example, <code>NOT</code> is explicitly set to 13 bits, while the switch after it is set to <code>x</code> and infers the width from the <code>NOT</code>.  The width bubble on the switch has a darker background to indicate that it is being inferred.

Bit width inference is especially useful when creating custom components, as the <code>Input Pin</code> is one of the components that allows <code>x</code> width.  For example, if we wanted the opposite of a <code>MUX</code> (demultiplexer or <code>DEMUX</code>), we could build a custom component similar to the following:

[[File:Bit_width_demux]]
Description	What you type	What you get
Italic	''Italic text''	Italic text
Bold	'''Bold text'''	Bold text
Bold & italic	'''''Bold & italic text'''''	*Bold & italic text*
