A. Design a combinational circuit that generates the 9's complement of a BCD digit. Develop and simulate a data flow model (don't use the behavioral model for this component) of a circuit that generates the 9's complement. B. Design a combinational circuit that describes the quadruple 2X1 multiplexer using a behavioral model. Develop and simulate a behavioral model (don't use the data flow model for this component). C. Design a combinational circuit for BCD adder. See Figure 4.14 of the textbook for the whole design of the BCD adder. Develop and simulate a data flow model (don't use the behavioral model for this component) for the BCD adder. D. Integrate the whole components of the system by developing and simulating a structural model of Figure 1. In your design, make sure that (1) the BCD adder should be described as a data flow model in a separate module, (2) the 9's complementor should be described as data flow model in a separate module, and (3) the quadruple 2X1 multiplexer be described as a behavioral model in a separate module. Finally, all the system components are to be instantiated in a top-level module using a structural model.

Question
use verilog to solve this

Transcribed Image Text:This project is to be done individually. 1) You need to submit your codes. 2) Write a report for
your results by providing the code and the simulation results of every component as well as the
whole system.
NOTE:
The grading of the project will be via discussion.
This project should be implemented in Verilog HDL using Quartus software
DO NOT:
Give/receive code or proofs to/from other students
Use Google to find solutions for assignment
DO:
Meet with other students to discuss the project (it is best not to take any notes during such meetings, and
to re-work project on your own)
Use online resources (e.g. Wikipedia) to understand the concepts needed to solve the project
In this project, you need to implement a BCD adder-subtractor circuit shown in Figure 1. You
need to build the system components separately using Verilog HDL. Then, you have to integrate
the different system components to build the whole system. Each of the system components,
as well as, the whole system should be verified using simulation.

Transcribed Image Text:A. Design a combinational circuit that generates the 9's complement of a BCD digit.
Develop and simulate a data flow model (don't use the behavioral model for this
component) of a circuit that generates the 9's complement.
B. Design a combinational circuit that describes the quadruple 2X1 multiplexer using a
behavioral model. Develop and simulate a behavioral model (don't use the data flow
model for this component).
C. Design a combinational circuit for BCD adder. See Figure 4.14 of the textbook for the
whole design of the BCD adder. Develop and simulate a data flow model (don't use the
behavioral model for this component) for the BCD adder.
D. Integrate the whole components of the system by developing and simulating a
structural model of Figure 1. In your design, make sure that (1) the BCD adder should be
described as a data flow model in a separate module, (2) the 9's complementor should
be described as data flow model in a separate module, and (3) the quadruple 2X1
multiplexer be described as a behavioral model in a separate module. Finally, all the
system components are to be instantiated in a top-level module using a structural
model.
