介绍了应用FPGA芯片和硬件描述语言(VHDL)设计微波炉控制器系统的方法。系统使用VHDL编程实现各底层模块的功能，顶层的设计采用图形输入完成。论文主要阐述模块化设计的思想和状态图的描述方法，以及他们在硬件描述语言中的应用，并展示了其在Quartus II 开发系统下的仿真结果。-This paper introduces the application of FPGA chip and the hardware descr iption language (VHDL) method for controller system design of microwave oven. The system uses the VHDL programming functions of the underlying module, the design by the graphic input complete. This thesis mainly discusses the idea of modular design and state diagram describing method, and their application of hardware descr iption language, and show it in the Quartus II development system under the simulation results.
