4 to 1 mux quartus software

When sel is at logic 0 outi 0 and when select is at logic 1 outi 1. The multiplexer mux functions as a multiinput and singleoutput switch. Create a 2 to 1 mux that has a data width of 4 bits. The input data lines are controlled by n selection lines. In this article, we will discuss the designing of 4. The output data lines are controlled by n selection lines. Therefore, you should already be familiar with basic quartus terms and processes. Multisim mux design, mux in multisim can be used in various. You will be creating a simple 2 to1 multiplexer to do this. A logic 1 on the sel line will connect the 4 bit input bus a to the 4 bit output bus x. Using the assign statement to express the logical expression of the circuit. The multiplexer will select either a, b, c, or d based on the select signal sel using the assign statement. I am very new to vhdl and i am trying to code a mux, i am close but need a little help library ieee.

Perform the following steps to implement the threebit wide 5to1 multiplexer. The reader is expected to have access to a computer that has quartus ii software installed. For example, if n 2 then the mux will be of 4 to 1 mux with 4 input, 2 selection line and 1 output as shown below. Please allow a little time for this interactive demonstration to load. In this, m selection lines are required to produce 2m possible output lines consider 2m n. Click next at the bottom of the eda tool settings page 4. Most, if not all of you have never used these software packages. In any case, you have to combine the outputs of the 16 andnand gates to form the complete multiplexer. Thus, a demultiplexer is a 1 ton device where as the multiplexer is an n to1 device. The detailed examples in the tutorial were obtained using the quartus ii version 5. This tutorial assumes that you have successfully designed and simulated a 1 bit 2 1 multiplexer using gates as described in the first quartus tutorial.

It consists of 1 input line, n output lines and m select lines. Modeling styles in vhdl modeling styles in vhdl modeling style means, that how we design our digital ics in electronics. Starting a project with altera quartus ii and creating a system with qsys duration. Program and test the circuit on an altera de2 board. Design a circuit for this mux by hand using and, nand, nor, not, and or only logic gates. View blocks such as and gates, mux s, adders, and registers new in quartus ii 4. Subscribe please leave a comment, like or shareit helps me a lot. You can find the detailed working and schematic representation of a multiplexer here now lets start the coding part. I dont see a multiplexer symbol in the quartus library, unless i open the max ii folder. The general block level diagram of a multiplexer is shown below. The intel quartus prime pro edition software supports the advanced features in intels nextgeneration fpgas and socs with the intel agilex, intel stratix 10, intel arria 10, and intel cyclone 10 gx device families. Sdi 4 x 3g to 12g mux design store for intel fpgas. Multiplexer mux select one input from the multiple inputs and forwarded to output line through selection line. Save the files to the same temporary directory as the quartus prime software installation file.

As with the multiplexer the individual solid state switches are selected by the binary input address. The vhdl code for implementing the 4 bit 2 to 1 multiplexer is shown here. Im trying to build 5 to1 mux using four 2 to1 multiplexers kevin777 mar 7 15 at 9. After downloading the design example, you must prepare the design template. The schematic representation of a 2 to 1 mux is used to structurally build a mux with a 4 bit wide data bus.

Design of 4 to 1 multiplexer using if else statement. A logic 0 on the sel line will connect input bus b to output bus x. Building simple applications with fpga springerlink. I am sure you are aware of with working of a multiplexer. Quartus ii simulator tool supports functional and timing simulation. How to make vhdl testbench for mux 4 to 1 and inputs are 4bits and output is 4bit hi. And to control which input should be selected out of these 4. The device features independent enable inputs ne and common data select inputs s0 and s1. Digital circuit can be r epresent in different ways such as gate level representation, transistor level representation e tc.

The intel quartus prime standard edition software includes extensive support for earlier device families. In this post we are sharing with you the verilog code of different multiplexers such as 2. Click next at the bottom of the new project wizard. Learn more vhdl prog to implement 8to1 mux using 4to1 structural modelling. Note that the signal out is declared as a reg type because it. Create a hardware level schematic using block diagrams of 2 to 1 mux and the seven segment display module. Since you have mentioned only 4x1 mux, so lets proceed to the answer. A mux with 2n input lines have n select lines and is said to be a 2n. Draw and simulate the complete mixedlogic circuit in. For the love of physics walter lewin may 16, 2011 duration. You should see the main quartus ii window similar to figure 1. For example, if n 2 then the demux will be of 1 to 4 mux with 1 input, 2 selection line and 4 output as shown below. And to control which input should be selected out of these 4, we need 2 selection lines. Legrand fuses 18kw motor 140 10 am legrand fuse legrand 390 61 legrand fuse 123 10 legrand bs 3535 115 to 24 2.

The figure below shows the block diagram of a demultiplexer or simply a demux. Posted by kishorechurchil in verilog code for 4 bit mux and test bench tagged. The selection of the input is done using select lines. If you want to use addon software, download the files from the additional software tab. Create new project by going to filenew project wizard 3. This method will let the program decide what to include in the sensitivity list.
