![]() ![]() In turn, actual power management can be achieved. ![]() One can sort out the requirement of a particular block in the device. With this, managing the power and timing of the device becomes flexible. An advantage of this approach is that one can know the flow of signals from input to output. Design in this paper shows a brief RTL schematic of a fully functional vending machine using mealy finite state machine (FSM). For the proposed design, reduced power consumption of 33.59 mW and a reduced gate delay of 1.024 ns at a frequency of 5 MHz are estimated. As a result, we get a readable RTL schematic of a vending machine that accepts three currencies and operates on three different products. Subsequent steps include optimization techniques, deriving Boolean expressions, and describing the design (behavioral modeling) using Verilog HDL in Xilinx VIVADO and Xilinx ISE. Modeling the machine is done using the finite state machine technique, which uses a list of its states. ![]() ![]() The proposed design shows minimum power consumption for a good range of frequencies. In this paper, we demonstrate a register-transfer level schematic of a vending machine that facilitates understanding of the actual design and precise circuit analysis. ![]()
