8 To 1 Multiplexer Verilog
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 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.Figure 2. Truth table of 8-to-1 multiplexer 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.Figure 3.

This page of verilog sourcecode covers HDL code for 8 to 1 Multiplexer using verilog. Following is the symbol and truth table of 8 to 1 Multiplexer. 8 To 1 Multiplexer Vhdl a multiplexer (or MUX) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line. A multiplexer of 2n inputs has n select lines, which are used to select which input line to send to the output.
