Objective The objective of this project is to experiment with the design and implementation of synchronous sequential circuits. Project Description Almost all of the real world electronic systems are designed with the help of one or multiple finite state machines. This project considers a finite state machine controller for a “coin to bills converter machine. To help needy children, a generous company has decided to offer a $1 food voucher for every 70 cents dropped into the machine. You are required to design the state machine for the specifications provided below. Specifications The machine accepts only dims (10 cents) and quarters (25 cents). The output $1 food voucher should be dispensed when the total coin amount reaches 70 cents. If the amount exceeds 70 cents, a binary indicator (flag) is triggered. For the project, there should be a lbit input, and 3 bits output. The output reflects 1 bit (out) for voucher (V) dispensing and 1 bits for the change (C). The specifications are as follows: Asynchronous IN Coin Reset Out Voucher|C|Change $1 Out 10 cents IN 0 Enable Coins to Bill converter 0 No No Clk Change 1 25 cents 1 Yes 1 Yes SO S1 Current State SN . The figure illustrates the input and output to the controller. The asynchronous Reset input is to reset the state machine to its IDLE state. As the food voucher is dispensed, the state machine should reset itself to its initial (IDLE) state. There should be 2 outputs denoting the following: 1 bit – Denotes the $1 out, which should be turned ON when the input amount reaches or exceeds 70 cents. 1 bit – Denotes that the change (amount exceeding 70 cents) is to be dispensed. The logic values are listed in the table above. You are to develop the state table and determine the number of bits “N” required for denoting the current state and determining the number of flip-flops). The 'clk' input should be given from the function generator with the following settings: FUNC = SQUA, FREQ=0.5Hz, AMPL = 2.5v, OFFSET = 2.5v .
