Verilog Based Automated Retail System

This paper presents to development of an automated retail system that dispenses three products of different prices. It uses Verilog HDL with the Xilinx ISE tool, providing precise control over the circuitry. The vending machine has 24/7 availability, making it a convenient option for users. The system accepts various coins, using a Finite State Machine (FSM) design to increment its internal state accordingly. Once the system reaches the correct state, it dispenses the selected product and returns the change, if applicable. The system also has a stock management feature to monitor inventory levels for each product. The design is tested and debugged using simulation tools to ensure its reliability and efficiency. Finally, we can implement the design into a physical vending machine and test it under realworld conditions. The use of Verilog HDL allows for a high level of control and flexibility in the design of the system, making it possible to create a reliable and efficient automated retail system.
