Syntax
2x1_MUX {[Subcircuit-label-n] [label-n]}
# where, the Subcircuit labels are D1, D0, S and Y
# All Subcircuit labels are mandatory
# Order is arbitrary
Example
2x1_MUX D1 A D0 B S C Y D
# (D1 and D0 - Data inputs), S-Select input,
# Y-Output, Order of the Subciruit labels doesn't matter
This block selects one from the two Data inputs based on the logic level at the Select line/Select input and passes to the output, while the other Data input which isn't selected, doesn't influence the output.
