It is used to write a module for 4x1 mux. A short summary of this paper.

Digital Electronics Laboratory

Module contains stimulus to check functionality of the design and is primarily used for functional verification using simulation tools.

. In this IC the op is the same as the ip. An example of a 4-bit adder is shown below which accepts two binary numbers through the signals a and b which are both 4-bits wide. Gate level modeling is used to implement the lowest-level modules in a design such as multiplexers full-adder.

4x1 multiplexer Full adder Single Port RAM. The best example of a 4X1 multiplexer is IC 74153. A multiplexer is a simple circuit that connects one of many inputs to an output.

A digital multiplexer is. Since an adder is a combinational circuit it can be modeled in Verilog using a continuous assignment with assign or an always block with a sensitivity list that comprises of all inputs. In this case D3 is transmitted to the output and qD0.

If the control input is changed to AB 11 all gates are disabled except the bottom AND gate. Multiplexing means transmitting a large number of information units over a smaller number of channels or lines. The design of this using 4X1 multiplexer is shown in the following logic diagram.

The gate-level circuit diagram of 4x1 mux is shown below. Hence the design is instantiated and called d0 inside the testbench module. One OR gate only used to collect inputs.

NOT gates as a selector to connect inputs to output. The output of DIFFERENCE is similar to the output SUM in the full adder circuit however the BARROW op is not similar to the full adders carry output however it is inverted as well as complimented like A B A -B A twos complement of B.
