Designing an Elevator Controller Using VHDL

In general, the success of an industrial establishment depends largely on the control strategy of supervision and control operation systems. This project aims to design an elevator controller for a four-storey building, to model an elevator controller that has 4 outputs, two of them (UP, DN) for motor direction and the others (RUN) to turn the motor on or off, while the other one is to close or open the door (Door). The controller has 4 bus inputs (3 down to 0) making a total of 16 inputs and a clock input. CUR_FLR to indicate the current floor (Sensors on the shaft of the elevator), REQ FLR to indicate the requested exit floor (Floor buttons inside the elevator's car), REQ UP and REQ DN to request the elevator's car and indicate the requested direction. There are outputs to run and direct the elevator's motor. The design of The Elevator is undertaken in Altera MAX+plus II software, using VHDL. The process of testing is carried out during modeling the process to ensure that the design is working as expected. Altera MAX+plus II software tool is used to synthesize the VHDL code which helps to compile the design.
