# You Are To Design The State Machine And Combinatorial Circuitry For The Lift Control 3683776

This assignment is the simple design assignment. You are given a problem, need to create truth
tables, Karnaugh maps and finally minimum Sum-Of-Products equations
You are designing the control system for a Minimum Viable Product lift. The lift has three floors, 0,
1 and 2. There are push buttons for each floor to summon the lift, and three buttons inside the lift to
designate the desired destination floor for the lift.
Your submission must be typeset, Karnaugh maps can be produced as Tables, or spreadsheet
matrices. NO hand drawn or scanned input will be graded.
Motor Control Outputs
Your control system needs to interface with the motor system for the lift. The motor system takes
two bits of input, and follows the following truth table:
You are to design the state machine and combinatorial circuitry for the lift control system. Your
state machine needs to keep track of the last floor the lift was on, the floors that need to be visited
and the current direction of the lift.
The state is held in the following D flip flop groups:
Last floor visited (Two flip flops)
Next floor to visit (Two flip flops)
Current Direction (Two flip flops)
Floors that need to be visited (Three flip flops)
The meanings of the bits in these flip flops will be as follows: Document Preview:

They are the three floor buttons, one on eachfloor to summon the lift and the three buttons inside the lift. Each button goes high when the button is pressed and reverts back to low when the button is released.ELEC242 1 of 3 2019 Session 2Macquarie University Assignment 1TaskYou are to design the state machine and combinatorial circuitry for the lift control system.
