The Design, Simulation, Verification and Implementation of Vending Machine Based on FPGA

Vending Machines or Vendors are more and more popular in modern society. Depending on the high autonomous level, it can satisfy customers and complete the merchandise process without any human labor input. And there are various vending machines with all different functions available, but basically, they are all controlled and operated by middle to large scales digital circuits. The purpose of this study is to apply the knowledge about the whole process of digital circuit design, meaning coding, simulation, verification, synthesis and implementation to design a general model of vending machine based on FPGA (Field Programmable Gate Array). The vending machine model is written in VHDL (VHSIC Hardware Description Language), and be implemented and tested on a Xilinx Spartan 3E FPGA development board.
