In this project, we are doing VHDL implementation of model of Vending Machine. A vending machine is an automated machine that provides items to consumers after coin is inserted into the machine. Simple vending machine using state machines in VHDL. A state machine, is a model of behavior composed of a finite number of states, transitions between those states, and actions.It is like a "flow graph" where we can see how the logic runs when certain conditions are met. Our work is implement model of Vending Machine on VHDL with specific define case. In project we are implementing digital circuit on VHDL using Xilinx ISE IDE. This is only language and software based project. We are not going to implement this model on any programmable device such as FPGA and CPLD.
