Lab LogicWork

Goal:

The purpose of this project is to create Finite State Machine (FSM) which can detect a certain eight-digit binary sequence in a continuous serial binary input stream. When the correct sequence is detected, the single output signal should be a logical true value, in all other cases it should be a logical false. This project is designed to allow a gradual transition from strictly combinational circuits to a simple sequential circuit.

Problem Statement: The “Gottcha Anti-Theft” Machine

There are many anti-theft devices on the market that attempt to foil a would-be robber from starting your car and driving off with it. One popular item has a keypad like a touch-tone telephone. In order to start your car, you must key in a secret four-digit decimal code, such as ‘3719’. It only “remembers” the most recent four digits you have keyed in. Thus, the sequence ‘3723719’ will let you start your car.

For simplicity here we use a code based on a sequence of eight bits, and use two push buttons to enter a sequence serially (as shown in Fig. 1). Each press of a button enters the corresponding digit. As you key in the bits in sequence, the device outputs E = 0 until the most recent eight bits agree with a built-in secret code byte. Then E switches to 1.

There are 2 questions for this lab. Use this 11011001 for secret key. This is require to use LogicWorks version 5, I have full version if you don’t have it. Please follow the instruction very carefully this worth a lot of points!
