Assessment Guide ITEC615 Fundamentals of Information Technology TP3, 2022 Assessment 2 Assessment Artefact: Logisim circuit & Lab report Weighting [30%] Task Description: You have to build (and test) the following digital logic circuits in the Logisim simulator and write a short report that describes your circuit. The maximum mark that you are able to achieve in AT2 will be determined by the difficulty of the circuit you decide to build (Option 1: Part A only; Option 2: Part A and B). Circuit Options:

OPTION1: Part A only
3 to 8 Decoder	15
Selection Logic	15
Name, labels, layout, file type, LED	5
Total	35
OPTION2: Part A and Part B
Part A as above	35
Lock works properly	5
Count losses	5
Count wins	5
Comparator works correctly	5
Remains locked after n games	5
Total	60

Please note: It may be better to have a fully functional and neatly drawn simple circuit than a complex one that is messily constructed and/or does not function properly. Labelling: You must label each circuit and template that you construct with the Annotation tool and ensure that all the inputs are labelled as instructed in this sheet. Each circuit and template must be labelled with: 1. Name and student ID 2. An appropriate label for each input 3. An appropriate label for each output 4. An appropriate label for the template that describes its function Note: Be careful, before submission, test your circuit if it works as required. Testing: You will need to test various possible combinations for the inputs S1, S2, S3 and S4 and check if the desired output is obtained (for Part A). You do not need to submit your tests. For Part B, you will have to test if the ultimate winning signal is generated, when the desired number of games is won by any player. Requirements: For this assessment you are required to implement a simple dice game, using a digital logic circuit. The game will have two players. For each round, both players will roll a single 4-sided die. The result of each die roll will be used to determine the winner. The winner for a round is decided by the following rules: A win is recorded for a player only if the results of the dice are consecutive numbers. The player with the higher number wins.

• Example 1: Player 1 rolls a 2 and player 2 rolls a 1. The numbers (2 and 1) are consecutive, and player 1 has the higher number (2). Player 1 wins this round.
• Example 2: Player 1 rolls a 3 and player 2 rolls a 4. The numbers (3 and 4) are consecutive, and player 2 has the higher number (4). Player 2 wins this round.
• Example 3: Player 1 rolls a 2 and player 2 rolls a 4. The numbers (2 and 4) are not consecutive and neither player wins. The round is a tie.
• Example 4: Player 1 rolls a 3 and player 2 rolls a 3. The numbers (3 and 3) are not consecutive and neither player wins. The round is a tie.

Note: These are just a couple of examples. There are more cases that result in a win for each player. Your circuit must correctly determine the winner for all cases. For this assessment, the die rolls will be represented by two inputs. Inputs are named as S1 and S2 for the 1^st Player (P1) and S3 and S4 for the 2^nd Player (P2). The table below shows the assessment of bits to each die roll for players P1 and P2 Part A Circuit Option 1: Part A Only (35 marks): The implementation for this part must use only basic logic gates (AND, OR, NOT, NAND, NOR, XOR) with maximum 2 inputs. You are required to implement a circuit in which each player inputs their signal and an output indicates which player wins. The outputs (marked as P1 and P2) will be two LEDs, one which is lit if Player P1 wins, the other which is lit if Player P2 wins. If neither player wins then no output LED should be lit. Part B Circuit Option 2: Part A and Part B (60 marks): For this part, the ultimate winner of the game is the first player who wins n rounds; where n is a number between 1 and 7. Using the same circuit as Part A, add additional circuitry to determine the winner based on the selection of n. For this part only, the more advanced counter and comparator circuits (only those two) from the Logisim circuit library can be used. The number of rounds required to win ranges from 1 to 7 and should be set via a combination of three separate inputs: X1, X2 and X3 (Note: You can combine the 3 inputs into a single 3-bit input). The circuit will have two outputs (marked as P1 and P2) which will be LEDs. The P1 LED is lit if Player P1 is the ultimate winner (first to win n rounds), the other is lit if Player P2 is the ultimate winner (first to win n rounds). Note that the initial values for X1, X2 and X3 are 0,0,0 indicating that the game has not been started. Note: For Part B you may need to add buttons to reset your count of how many games have been played so that you can test it. You may also need to add a clock input (as a button) to ensure that values are only updated when the circuit is stable. You may also need to add another input to indicate whether the game has started or not and use that to ensure that neither P1 nor P2 output LED is lit when the game has not started. Report: Your report (3 5 pages) must contain the following sections:

2. Your details: Name, student number, and email address of group members
4. Circuit Name: The name of the circuit you have selected to build and draw
6. Circuit Function: A brief (100-200 words) description of the functions of each of your circuit describing in your own words how the circuit operates.
8. Circuit diagrams: A diagram of your circuit including all templates and their contents. You must draw this diagram yourself using the Logisim logic simulator. To include a circuit in your report, please take a screen shot of the circuit and paste the screenshot into your report. Copying and pasting from the lecture notes or other sources is NOT permitted.
10. Truth tables: Show all possible inputs and outputs for each component individually. The column headings in your truth table should correspond to the labels on your circuit diagram.
12. References: This is where you will show your evidence of engagement. Your circuit design and report must provide evidence of engagement with this unit\'s learning materials.
14. Checklist: You must submit the assessment checklist. The template is at the bottom of this document.
