Example $2$

Circuit Design Using Modular Approach

The Project: Use Quartus II to design the following circuit:

$W\frac{?}{b}=ar(A)\frac{B}{b}ar(C)D+AB\frac{C}{b}ar(D)+\frac{A}{b}ar(B)\frac{C}{b}ar(D)\frac{+}{b}ar(A)BCD$

The Procedures:

Analyze the original design problem

Break up the problem into smaller design problems: $W=x+Y,$ where

$x\frac{?}{b}=ar\frac{A}{b}ar(BC)D+AB\frac{C}{b}ar(D),$ this is the Example $1$

$Y=\frac{A}{b}ar(B)\frac{C}{b}ar(D)\frac{+}{b}ar(ABCD),$ this is the Project $1$

Use Quartus II to modify the Boolean X project inside folder Example $1$:

a$.$ Remove all pins.

b$.$ Create a Block $($chip$)$ Symbol for this sub$-$circuit.

c$.$ Save and compile the project.

Use Quartus II to modify the Bgolean$\_$Y $.$ project insider folder Project $1$:

a$.$ Remove all pins.

b$.$ Create a Block $($chip$)$ Symbol for this sub$-$circuit.

c$.$ Save and compile the project.

Inside the EET $230L$ folder, create a folder called, Example $2.$

Inside the Example $2,$ use Quartus II to create a folder and a project called, Bqolean W;

In the Boglean W folder, follow the procedures of Quartus II Tutorial II to combine the two sub$-$

circuits; import all necessary files.

Save the project, then, compile the project.

Complete a timing analysis.

Assign the pins PIN$\_$G$4($SW$3)$ to A$,$ PIN$\_$H$6($SW$2)$ to B$,$ PIN$\_$H$5($SW$1)$ to C$,$ PIN$\_$J$6($SW$0)$ to D;

and assign PIN$\_$J$3($LED $2)$ to W$.$

Save and compile the project.

Download your design to a DEO board.

Use the truth table to provide the inputs, and verify the output.

Requirements: After a successful testing, demo your project to your instructor.
