【正文】 y. 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, pilation, 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 be observed more clearly the vending machine operation. Keywords: vending machine controller。 VHDL III 目 錄 第 1 章 緒論 .................................................................................................................. 1 自動(dòng)售貨機(jī)的起源
