I written a Verilog code for and gate using two Nand gate Instantiation is used when we want to repeat a particular function/ module for different sets of input. I need help implementing a mux synchronizer on Verilog. Note that the signal out is declared as a reg type because it is used in a procedural block like always. You can find the detailed working and schematic representation of a multiplexer here. Hardware schematic for 2:1 MUX:RTL hardware schematic Behavioral Modeling. Take the output of the 4-to-1 mux and connect it to one input of a 2-to-1 mux. Where is the code for 16 to 1 using 8 to 1. If we dont use a clock, some of values from inputs or calculation algorithms may be delayed so the result may be wrong. All rights reserved. You will need to instantiate the basic (reusable) modules separately, and then select the outputs via F. There are many ways to write simple code in verilog.it depends on requirement some time here I presented different ways to write this code.

It describes the combinational circuit by their functions rather than their gate structures. Embedded hyperlinks in a thesis or research paper. Here I am to help you to get your job done. We have implemented the above barrel shifter in verilog. |5|6| |7|8| Well structurize for each of the gates separately. I am sure you are aware of with working of a Multiplexer. There are many ways you can write a code for 2:1 mux. For example, a 4 bit multiplexer would have N inputs each of 4 bits where each input can be transferred to the output by the use of a select signal. Y is the output and D0, D1 and S being input are written after. In such cases, we have to use the enable input. B. The input signals are D0 and D1. Are you sure you want to create this branch?
