摘 要 本论文介绍了应用FPGA芯片和硬件描述语言(VHDL)设计微波炉控制器系统的方法。论文模块化设计思想和状态图描述方法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 微波炉控制器系统是一个实用型的系统，系统不仅操作简单而且烹调效果好，可以按固定程序一些家常菜，采取分时、分火力加热，。以下几个模块：输入模块、控制模块显示模块。输入模块按键扫描和键盘译码控制模块包括状态转换控制、数据装载、烹饪计时、温度控制、音效提示等显示模块涉及到显示译码和指示灯的闪烁。 经过需求分析，设计，，并利用FPGA实现相应的功能，经过波形仿真、下载调试，验证了设计方案的可行性及实现方法的有效性，基本实现了系统的要求。关键词：FPGA；VHDL；微波炉；状态图；定时器 Abstract This paper introduces the method that applying FPGA chip and VHDL to design the control system of microwave ovens. The system uses VHDL to fulfill the function of each bottom module and the design of the top layer is completed via graphic entering. This paper mainly illustrates the idea of module design and description method of state chart and that their application in VHDL and simulation results in the develop system of Quartus II. Microwave controller system is a utility-type system that includes not only the function of simple operation, but also good effect of cook. According to fixed routine, you can cook some homely dish via taking different time and different level firepower to heat, and this can not only save time, but also save energy. It mainly includes a couple of modules as follows: input module, control module and display module. Input module fulfills key-press scanning and keyboard decoding, control module includes status switching control, data loading, cook time, temperature control, sound effect tip and so on, display module comes down to display coding decipher and the flashing of indicator light. Through the analysis of requirement, detailed function design, coding, module connection, using FPGA to fulfill relevant function. Through waveform simulation, download debugging, it verifies the feasibility of the design and the effectiveness of realization method and basically fulfill the requirement of the system. Keywords: FPGA, VHDL, Microwave oven, Status chart, timer目 录 1. 绪论 1 1.1. 任务的提出 1 1.2. 课题的内容和要求 1 1.3. 设计的目的和意义 2 2. 关键技术简介 3 2.1. FPGA简介 3 2.2. VHDL语言概述 3 2.3. Quartus II 开发系统简介 5 3. 系统总体设计
