VHDL Finite State Machine Based Elevator Controller

Abstract:

This paper analyzes the versatility of VHDL FSM coding and its presentation of various outputs. The analysis is based on the elevator controller project. The elevator controller was chosen because it serves as a typical digital controller system which boasts of numerous outputs like motor, lights, floor numbers, fire alarm, overweight ,beep ,direction arrows and others .Although not all outputs mentioned here are shown in the project codes but the few shown can illustrate how versatile is the VHDL FSM output representation. Other outputs can easily be added according to requirements.
