Hi,

package is for procedures and functions. (not 100% sure)

If you want to instantiate "genericMultiplexer" (written in genericMultiplexer.vhd),

You have to write in architecture of your "multiplxer.vhd" something like 


genericMultiplexer_i :  ENTITY work.genericMultiplexer( genericMultiplexerArchi )
generic map ( selectorWidth => mySelectorWidth ) -- mySelectorWidth ?
port map ( 
  selector  => selector,
  dataInput => dataInput,
  output    => output 
);

It is enough.

Your package body is empty, and your package is useless. (In my opinion)
