As a representative of commercial machinery automation vending ,the vending machine business is widely used in public places ,has bought great convenience to peoples lives. This paper describes the software design and hardware design based on FPGA vending machine controller, the vending machine controller module consists mainly of eight modules: shopping module, price module, coin module, timing module, price comparison module, reset module, shopping display module and digital display module. After parity processing module for selected commodity prices and the amount of investment comparison, the corresponding change information delivery through LED lights and the digital display module display. This design using VHDL hardware description language programming to describe the basic function of eight modules. Performed on the Quartus II software platform for design, compilation, integration, optimization, simulation and ultimately the resulting object files downloaded to the target FPGA chip. Completing the realization of the function of the vending machine in the ZY11EDA13BE experimental system. Coin, shopping request through the switch, keyboard and the other operations. Through digital tube and light display system running result, which can
