5 VHDL Implementation of a 2-to-1 MUX A multplater is a circuit that selects between several inputs and forwards it to a single culput. In general, a 2"-L-I MUX
has 2 Inputs with n selectars. A schematic diagram ala 2-to-I muliplexer is given below.

According to the above schematic, the 3-10-I multiplever outputs the input signal A wten the selector signal is equal to
O otherwise Gutputs the input signal B. In this cah, you will implement this 2-10-1 multiplexer in VIDL using structural
and behavioral styles. In the structural modeling of the 2-ID-I muluplecer in VHDL the multiplexer la implemented
using AND, OR OF NOT ples only. More specifically, the structural description of the malüplexer literally realizes its
boolean funcdon. Describe the boolean function in VIDL using AND, OR O NOT gates only. Use the folosing entity
declaration for your VIDL. description of the 2-10-1 muldplexer

Once completed, you will describe the architecture of the 2-to-laulupler using behavioral style. In the behavioral
description, you desroribe de behavior of your target circuit and the synthesis tool arvates a gate-led Layout of your de-
sign. Use a single VIIDL, seled assignment only and the entity declaration below to implement a behavioral descripcion
of the 2-to-1 malaplexer (ree the previous VIIDL assignment for more details).
