DOOR SECURITY SYSTEM A simple security system for two doors consists of a card reader and a keypad. Card Reader Combinational Logic - To Door 1 To Door 2 To Alarm Keypad A person may open a particular door if he or she has a card containing the corresponding code and enters an authorized keypad code for that card. The outputs from the card reader are as follows: No card inserted Valid code for door 1 Valid code for door 2 Invalid card code AB 1 1 0 0 1 0 0 To unlock a door, a person must hold down the proper keys on the keypad and, then, insert the card in the reader. The authorized keypad codes for door 1 are 101 and 110, and the authorized keypad codes for door 2 are 100 and 011. If the card has an invalid code or if the wrong keypad code is entered, the alarm will ring when the card is inserted. If the correct keypad code is entered the corresponding door will be unlocked when the card is inserted. Design the logic circuit for this simple security system using 4 x 1 Multiplexers. Your circuit's inputs will consist of a card code A and B, and a keypad code C, D, and E. The circuit will have three outputs X, Y, and Z. If X or Y is equal 1. door 1 or door 2 will be opened; if Z is equal 1, the alarm sound. Design Procedure : 1. Draw a truth table for your proposed design. 2. Find simplified Boolean function for the output of this circuit (X, Y, and Z) by using Karnaugh map. 3. Draw a schematic diagram for the design. 4. Write HDL code to implement your proposed circuit and determine the output waveform (timing diagram) Report: 1. Your report which show all your design steps and thinking process. 2. Your report should include a fully labeled and correctly drawn schematic diagram of your circuit as it was tested. 3. Your reports will be done on a word processor (for single-spaced, 12-point text) and is to summarize the problem being solved, the major design decisions you made in solving the problem, and the problems you encountered and how they were resolved in completing the design. 4. Your Report should include the following subsections. Title Page o Title of your project Your design team: Name(s), e-mail addresses, o Lab Sections of you and your project partner(s) and Date Project Abstract Brief summary of the problem you are trying to solve (1-2 paragraphs). Table of Contents Design Part In this section you should provide step-by-step instructions on how to design your project. This section should include your simplifications, schematics, block diagrams and circuit HDL coding Design Review - Conclusion A summary of your experiences throughout the project what you leamed, what mistakes you might have made in planning, approach, etc.} What were the most important aspects of the project for you? Where did you spend most of your time? Design Constraints: Try to minimize the number of gates required
