8 To 1 Multiplexer Verilog Array

  1. Introduction


    An 8-to-1 multiplexer is a digital device that selects one of the eight inputs lines to the output line by using three-bit selection line. The block diagram of 8-to-1 Mux is shown in Figure 1. A 2n-to-1 multiplexer needs n bit selection line to select one of the 2n inputs to the output.
    Figure 1. Block diagram of 8-to-1 multiplexer

  2. Truth Table


    Figure 2 shows the truth table of the 8-to-1 multiplexer. I1 to I8 are the input lines, S1 - S3 are the selection lines and O is the output line.

  3. Verilog Module

    Figure 3 shows the Verilog module of the 8-to-1 multiplexer. The 8-bit ports In1 to In8 are input lines of the multiplexer. The Sel port is the 3-bit selection line which is required to select between the eight input lines. 8-bit port Out is the output line of the multiplexer.
