VHDL语言编程简单实例若干，适合于初学者(VHDL language programming simple example, suitable for beginners)

用三个按键控制pwm输出 key0控制是选着显示/改变频率或占空比 key1控制增加 key2控制减少 数码管显示频率或占空比 频率单位默认Hz（500-20KHz） 占空比范围（0.1-0.9）(Control PWM output with three keys Key0 controls display/change frequency or duty cycle optionally Key1 controls the increase Key2 controls are reduced Digital tube display frequency or duty ratio Frequency unit default Hz (500-20khz) Duty cycle range (0.1-0.9))

说明：  VHDL语言100例详解。详细讲解了用VHDL语言进行数字电路和数字系统设计的知识。用100个实例，不仅进行基础的门电路设计，而且还有较为复杂的数字系统设计。这些实例可以直接被调用。(VHDL Elaborates on 100 cases. Detailed account of VHDL for digital circuits and digital systems design knowledge. With 100 examples, not only for infrastructure gate design, but also more complex digital system design. These examples can be called.)

fpga的按键程序，实现按键和led的对应点亮。(The key program of FPGA realizes the corresponding lighting between keys and led.)

sdram FPGA verilog设计  有源码有设计文档

说明：  sd卡读写，仿真模型，testbanch测试文件(sdcard read write and sdcard model)
