public class Decoder
extends GenericRtlibObject

Decoder - decode an n-input value into 1 1-out-2**n code (active high). For example, the truth-table for a 3-bit decoder would be: 000 0000 0001 001 0000 0010 010 0000 0100 011 0000 1000 ... 111 1000 0000 Signals are expected to be SignalStdLogicVector objects.
