/*******************************************************************************
  Test bed for the Mux component

  The "Mux" component has the following characteristics:

    Select   (input)  -- N-bit control signal to select data signal
    Data-In  (input)  -- 2^N 1-bit data signals
    Data-Out (output) -- 1-bit data signal selected by control signals
