Assignment - Lift Controller 1. Aims • To work in a group to produce a digital design. To design a simple system using VHDL. • To use a modular approach to design a simple LIFT CONTROLLER. • To simulate the design using testbenches. • To implement and fully test the design on the DE0-nano board. To document the design, simulation, and testing in the form of a joint report. • To demonstrate the functionality of the final design. 2. Functional Requirements and Constraints • A lift calling and control system is to be designed. • A bespoke hardware interface using the DE0-nano board FPGA is to be designed. This interface is to use appropriate voltage levels suitable for the DE0-nano and should consist of the following: • a lift controller capable of moving personnel between four floors; call buttons (up/down) and LEDs at each floor¹ • • . doors open, doors closing and doors closed LEDs in the lift carriage floor select buttons inside the carriage a "bar graph" showing the position of the lift and the motion of the lift an emergency stop button which stops the lift at the nearest floor and opens the doors. • VHDL code and appropriate hardware is to be developed to control the lift, including a suitable algorithm to decide the motion of the lift carriage and which floor(s) it stops at. Suitable delays are to be implemented so as to represent the relative delays in a 'real' system. Enhancements to the design will attract extra marks. Additional hardware may be constructed on a breadboard if necessary. this will be different at the top and bottom floors * depending on your design there may be sufficient hardware on the DEO-nano board Assignment - Lift Controller 1.
