Jan 20, 2020 · In this article, we’ll write the Verilog code for the simplest multiplexer, i.e. a 2:1 MUX. Comparing 2:1 with 2^n: 1 (as mentioned before) we get n = 1, which is the number of select lines (input variables = 2, select lines = 1, output signal = 1).
A multiplexer (MUX) is a combinational circuit that connects any one input line (out of multiple N lines) to the single output line based on its control input signal (or selection lines) Usually, for ‘n’ selection lines, there are N = 2^n input lines. Nomenclature: N:1 denotes it has ‘N’ input lines and one output line.
Sep 19, 2024 · Verilog HDL code of 2:1 MUX. Design. // define a module for the design. module mux2_1(in1, in2, select, out); // define input port. input in1, in2, select; // define the output port. output out; // assign one of the inputs to the output based upon select line input. assign out = select ? in2 : in1; endmodule :mux2_1. Testbench. module test;
Apr 2, 2023 · 2X1 Multiplexer Verilog Code. Let's start with basic 2X1 MUX in gate level modeling. It has two inputs, one select line and one output. The boolean expression for 2X1 is given as $$Y = \overline S .I0 + S.I2$$ For this, we require two AND gate, one OR gate and one NOT gate.
Apr 15, 2024 · In this detailed walkthrough, we’ll dissect the Verilog implementation of a 2:1 multiplexer, exploring each aspect of the code and providing a comprehensive explanation of its functionality. Run on EDA Playground
Jan 5, 2023 · The boolean logic equation for a 2-to-1 multiplexer is. (A. ˉS)+ (B. S) where A is the first input and B is the second input. embed module mux2to1(sel, i1, i0, f); input i0, i1, sel; output f; wire nsel, w1, w2; not(nsel, sel); and(w1, i0, nsel); and(w2, i1, sel); or(f, w1, w2); endmodule.
Jan 22, 2017 · Verilog Code for 2×1 Mux. module mux2x1(out,a,b,s); input a,b,s; wire and_1,and_2,s_c; output out; not (s_c,s); and (and_1,a,s_c); and (and_2,b,s); or (out,and_1,and_2); endmodule. In a hierarchical design, all we need is to design a small block and construct a big block using these small blocks.
Feb 13, 2024 · This Verilog module implements various logic gates using 2x1 multiplexers (MUX). Each MUX takes two inputs and selects one of them based on the control input. Here’s a breakdown of the gates...
Sep 9, 2023 · In this tutorial, we've learned about the working principle of a 2x1 multiplexer, created Verilog code for the multiplexer, developed a testbench to verify i...
Feb 19, 2023 · Multiplexers, or MUXes, are fundamental components of digital circuits that allow selecting one of several input signals and forwarding it to a single output. In this post, we'll explain how to design multiplexers in Verilog and SystemVerilog, and provide examples to help you get started.
