BRACU authority finally decides to get a vending machine designed by its CSE

students. The authority gives the students the following specifications for the

vending machine:

a$.$ Only $20,50,100$ tk notes are allowed to cash in$.$

Now, design a Mealy FSM to buy a product worth $60$tk$.$

Deliverables:

State diagram of the FSM

Copy and paste the Verilog code

Output timing diagram if $100$ tk is inserted in the idle state. $($You must

show and explain the "purchase" and "cash$\_$return" variable$).$

Now suppose your machine can dispense two items at once and the item that is

purchased is also recorded. After a month of use, the university observes that

students mostly buy KitKats and a bottle of Pepsi. The authorities are concerned

about the health of the students. So they ask you to make the vending machine

smarter. Your task is to design an FSM that will detect whether a combination

of KitKat and Pepsi has been purchased more than $3$ times. If it has, your FSM

will output $1$ in the $4^{th}$ cycle.

You have two sensor data as input, one that detects KitKat and one that detects

Pepsi.

Deliverables:

State Diagram

Copy$-$paste the code

A screenshot of the waveform showing when the output is $1$

You will submit one single pdf that contains the deliverables of both questions.

Rename this pdf as your Name$\_$ID$.$pdf$.$ You will also the $.$v Verilog files that you

use in Quartus for both tasks after zipping them into one file. You can google

how to zip using WinRar or any other similar software.

ft first Don't Use Chat$-$GPT$.$

Use Quartus Software to solve this question.

You will submit one single pdf that contains the delverables of both part of questions.

You will also the v Verilog files that you

use in Quartus for both tasks after zipping them into one file and send them in this m'aill isratratul $07$

$[$this is actually one question but it has $2$ parts $(1,,),$ so Don't take misinformation regarding the number of

questions.$]$
