Hardware Lab 4: EEE/CSE 120 Design Project

Fall 2016

Background: The Scoring in Screwball

There is a game called Screwball.  Every time a ball is put in play, either player 1 scores a point or player 2 scores a point.  A winner is declared when one player is ahead by 2 points.  Starting with a score of 0:0 for P1 vs. P2, a game might progress as follows:

0:1       1:1       2:1       3:1 (P1 Wins!)

The Application: The Win Announcer

Your task is to develop a synchronous sequential machine that uses information about which player scores a point at each stage of a game to indicate BOTH when a player wins and which player wins.  Your design should include one reset input to initialize your WIN ANNOUNCER (this may be a synchronous or asynchronous input as you desire).  The outputs from your design should indicate BOTH when a win has occurred and which player is the winner.

All information to complete this design may not be specified.  Write down and report any assumptions that you make in your design.

Be sure to use debounced “logic switches” for driving the clock input to the flip-flops.

Deliverables

You are to design two CONCEPTUALLY different finite-state synchronous machines. A design which differs only by the type of flip flop used (e.g., J-K vs. D)or number of states is not considered conceptually different.

First, you will need to implement both designs using Logisimand demonstrate to the CSE/EEE 120 simulation TA’s in GWC 185 that both designs work correctly by the software due date (See Table 1 below). You will need to sign up at the front desk in GWC 273 for a time slot at which you will demonstrate your design to a TA in GWC 185. You also need to sign up for a simulation demonstration time slot on the Pink sheets.

You may demo this by either 1) opening your file using the computer reserved by the TA on duty or 2) asking the TA to test your circuit on your laptop.  You will need to bring with you a printout of your report template into which you’ve cut/pasted your Logisim circuits. It makes most sense to complete the lab template and print it before you go and demonstrate the designs to the TA. You must have your design simulation working before asking the TA to test it because you will be given only one chance to prove that it works.You must also be able to defend your design; the TA’s will be asking questions to make sure that your design is your own original work.  Upon completion of your simulation demonstration, the TA’s will sign and apply a grade to your report template.  You also need to include these simulations into your lab report template.

Second, you will need to implement ONE design using the TTL parts you used in earlier lab work and demonstrate to only a CSE/EEE 120 hardware TA that your circuit works correctly. You must complete this demo by the due date (See Table 1 below).  You will need to separately sign up at the front desk in GWC 273 for a time slot during which to build your hardware demo. After reviewing the simulation TA’s signature on your Logisim schematic printout, the hardware TA’s will test your design and stamp the design pages of your completed report template.  You must be able to explain why your circuit responds the way it does to a given input data stream. You must have your report template completed and bring it with you to your in-lab hardware demonstration. Your completed report template will be collected by the hardware TA at the conclusion of your demonstration.

You must use the design project template for your report.

Lab project make-ups will be allowed ONLY with written permission from your instructor.

You may discuss this project with each other; however, you must provide an individual report.  In addition:

• You must go to the GWC 185 individually to demonstrate your simulation of both designs AND (Write up the Lab Report BEFORE you come to the hardware lab).
• You must go to the hardware lab individually to build one circuit in order to have your individual report count.

Grading Policy

The grade will be allocated as follows:

30% Design Simulation With Logisim

• 15% for the design of the first circuit and demonstration.
• 15% for the design of the second circuit and demonstration.

70% Build One Design in the Hardware Lab and Lab Report

• 30% demonstration of one design in the hardware lab.
• 11% for documentation in the report of how the first circuit performs the application.
• 11% for documentation in the report of how the second circuit performs the application.
• 5% for establishing reasonable criteria for picking one design as the “best” design.  (The one design you build in the hardware lab does not need to be the “best” design.)
• 8% for picking a preferred, “best” design.
• 5% for following template guidelines.

5% (Extra Credit) Completed Self‑Assessment Worksheet

5% (Extra Credit) for signing up for a Hardware Demonstration time slot on a Monday, Tuesday or Wednesday. 10% extra credit for signing up for the SW Demonstration time on the first 2 days of the week (You must perform it on that day to get the extra credit)

LAB MANAGER’S RULES FOR PERFORMANCE

1. You will only be allowed to do the project during the assigned times.  If you miss the calendar dates, you will not be allowed to do the lab project unless you have a WRITTEN NOTE signed by your course professor.
2. Hardware Demo: You must have your lab report completed before you start the lab demo since you will need to give it to the lab TA at the completion of the demo.  (Having your report finished will help you complete the lab project in the allotted time.)  You will not be allowed to do any practice runs of the lab project inside of GWC-273.  You must be ready to complete the entire lab project when you come into GWC-273.  However, outside of GWC-273 you may consult with anyone you wish to obtain help in designing the lab project.
3. Hardware Demo: You will have ONLY 2 HOURS to complete the lab project in GWC‑273.  You must work alone with no lab partners to assist you.  No friends, relatives or tutors may be with you.  You may bring any textbooks, notes, reference books, lab notes, lab experiments, and lab reports into the GWC-273 lab area.  You will definitely need your PIN-OUT diagrams of the IC chips.  You will not be allowed to take any breaks from your 2-hour shift except for restroom and water.  (Sorry: but you cannot bring in your own breadboards and IC chips because that would give you an unfair advantage over other students in the GWC-273 lab.)
4. Notice: Make sure you do the project ONLY during the hours in which any EEE/CSE 120 Hardware Lab TA is on duty inside of GWC-273.  Only these TAs can assist, monitor and check-off your project.  TAs in other courses are not permitted to assist you do the lab project.
5. You will be able to use any of the IC’s we have in the lab for completing your project.  Check in the lab if you are not sure which IC’s are available.  Be aware that in GWC 273 we DO NOT have the following IC’s available:7421, 7430, 74133, 74174, 74375.
6. Hardware Lab TA’s on duty will assist you ONLY if there is broken lab equipment.  Hardware Lab TA’s will NOT assist you with troubleshooting or debugging your project lab design circuit.

Notice: If you are thinking of omitting this lab project from your schedule, be reminded that parts of this lab project may show up on the final exam for this course!

You can only design your circuit with the ICs that are available in GWC 273 lab:

74LS00

74LS02

74LS04

74LS05

74LS08

74LS32

74LS74

74LS86

74LS112

74LS126

Anything outside of those ICs, we do not have for the student to build their project lab inside of GWC 273 lab.

Students in their SW design can only use the ICs that we have in stock inside of GWC 273 lab
