Description

SECTION: 8L

Rules:
1. You need to submit the code, the compilation report, and the simulation report with a brief description of each of the problems.
2. Prepare your assignment in a doc file. For each of the problems, paste the code in the doc file (Not screenshot, copy-paste the code), add screenshots (full screen) of the compilation and simulation report and give a brief description of how your timing diagrams manifest expected outputs. The explanation can either be typed or scanned. Next, export the doc as pdf as StudentID_LabAssignment2_CSE460.pdf.

Problem 1: (marks: 8)
An FSM has an input w and an output z. The machine has to generate z = 1 when the following patterns in w are detected: 1010; otherwise, z = 0. The machine should reset when (Reset = 0).
Requirements:
A. What type of FSM method should be used?
B. Draw the state diagram,
D. Write the Verilog code
E. Run simulations, and verify your answer (timing diagram with the clock’s period = 50ns) with respect to the timing diagram chart in Table 1.
Table 1
Problem 2: (marks: 12)
You have to design a vending machine for a 15 Tk product. User’s money, returned money by the machine, and product bought condition is represented as mny (2-bit input), chg (output), and buy (1-bit output).
The vending machine can only accept inputs: no money (mny = 00), Tk 10 (mny = 01), and Tk 20 (mny = 10). If no money is inserted into the machine, it will immediately return the user’s money back. Once an acceptable input is more than or equal to 20 Tk, the machine immediately generates an output (buy=1), goes back to the initial state, and gives back the change (if required).
Requirements:
A. Draw the state diagram.
D. Write the Verilog code.
E. Run the simulation, and verify your answer (timing diagram with the clock’s period = 50ns) with respect to the timing diagram chart in Table 2.
