Design of Automatic 5 × 5 Dispenser with three kinds of payment modes using Verilog HDL

The Basic idea of this work is to design an Automated Dispenser that can dispense five different kinds of products and supports three types of payment modes of five different costs. The three different payment modes are UPI, CARD and CASH modes. The automated dispenser will provide change based on the product cost, it shows the number of products available as well. The proposed design is verified and implemented using VERILOG HDL and XILINX ISE14.7. We made an effort to calculate the power dissipation of this design using XPA tool in XILINX PlanAhead on 10MHz,100MHz and 500MHz operating frequencies. We used three different LVCMOS IO Standards: LVCMOS18, LVCMOS25, and LVCMOS33. This design has been tested SPARTAN-6, VIRTEX5 and KINTEX-7 FPGA boards. Based on that we have stated the suitable FPGA board for this automated dispenser. This automated dispenser can be an optimal choice for use in supermarkets, shopping malls, and all kinds of departmental stores, etc.
