A demultiplexer is a circuit that places the value of a single data input onto multiple data outputs. The demultiplexer circuit can also be implemented using a decodercircuit. Here we are going to work with 1-to-4 demultiplexer. A 1-to-4 demultiplexer consists of 1. one input data line, 2. four outputs, and 3. two control lines to make selections. ...
There are various styles of writing Verilog code in behavioral modeling for this circuit. 1. case statements 2. assignment statements 3. if-else statements Here we will be elaborating on the first two. Along the way, we would also emphasize some common design errors.
The basic building block in Verilog HDL is a module, analogous to the ‘function’ in C. The module declaration is made as follows: For starters, moduleis a keyword. It is followed by an identifier. Identifier=name of the module. After naming the module, in a pair of parentheses, we specify: 1. the direction of a port as input, output or inout. 2. Po...
First of all, we initiate by module and port declaration following the same syntax. We assign identifier as Demultiplexer_1_to_4_assign, input as A, din and output as Y. We also set up the size and type of the port, which can only be either input, outputs, or inout. Then we assign the output as the logical and operation of the select lines and data...
Simulation log relating to our truth table. We can observe that din is always 1; all combinations of A are made, the output can be verified easily. For example- A = 0, A = 0, see that the waveform of Y is high. Thanks for reading! If you have any queries, let us know in the comments section below!
